Chapter 1 Outline of the Project

1.1 Background to the Project

The Republic of Guinea extends over an area of 245,857 km² and has an approximate population of 10 million1. The capital city Conakry has been achieving economic development with its mainstay industries that utilize the harbor facilities as the physical distribution base, i.e., trading, food processing, building material processing, and distribution industries. As the economy has developed, the approximate population has increased from 110 thousand in 1960 to two million in 2010 (estimated).

However, the development of urban infrastructure has not caught up with this rapid increase in the population of Conakry City. Some urban problems such as traffic congestion and deterioration of living environments are frequently occurring. The population is increasing also in the surrounding area of Conakry City. Therefore, an integrated urban development plan for the city and its environs is needed.

Consequently, geospatial information to be used as the basis for infrastructure development plan is required to conduct well-planned urban development to deal with the urban problems described above. Although there are 1/50,000-scale National Base Maps created in 1951 for Conakry City, they have not been updated for about 60 years. There are also 1/10,000 maps created in 2010 by the National Observatory of the Republic of Guinea, however, they have low accuracy and do not have elevation data and therefore are not appropriate for the urban infrastructure development plan, in the same way as the 1/50,000 National Base Maps.

Against such a backdrop, the Guinean government requested the Japanese government to create large-scale topographic maps over an approximate area of 500 km² including Conakry City and its surrounding area in order to create geospatial information that will serve as the basis for infrastructure development plans.

In response, the Japan International Cooperation Agency (JICA) dispatched a study team for establishing a detailed plan in February 2012, discussed with the National Geographic Institute (Institut Geographique National: IGN) of the Ministry of Public Works and Transport, an implementing organization of the Guinean national government, regarding creation of topographic maps of Conakry City and its surrounding area and technology transfer related to it, and signed a Record of Discussion (R/D) as of February 24 th, 2012. This Project was implemented according to the above R/D.

1.2 Objectives and Basic Policies of the Project

This Project is aimed at: Creating 1/5,000-scale digital topographic maps and orthophotos of an area of ca. 520.79 km2

including Conakry City and its surrounding area; and Transferring the technologies for basic surveying and maintenance/updating of the digital

topographic maps. The Project Team set forth the basic policies shown in Figure 1-1 and carried out the tasks required

to implement this Project.

1.3 Project Implementation Period

This Project is implemented in a period from September 27th, 2012 to August 26th, 2016. The work in Guinea was initially planned to be implemented in September 2014 but was postponed

to April 2016 for the sake of safety due to an outbreak of Ebola hemorrhagic fever in the country. Consequently, the project completion date was changed from the one planned at the start of the project (the project was originally scheduled for completion on October 22nd, 2014 at the project start).

1.4 Counterpart

The counterpart (C/P) organization of this Project is the National Geographic Institute (Institut Geographique National: IGN). IGN is situated in the Ministry of Public Works (Ministère des Travaux Publics: MTP) and is responsible for managing and updating measurement outputs for the entire land of Guinea.

The development of geospatial information in Guinea dates back to 1914 when France created 1/200,000 topographic maps (an area of 50,000 km2) for the sake of railroad construction. Up to the beginning of the 1980s, topographic maps were developed with assistance from the Governments of France and Japan. However, political instability resulted in economic and financial deterioration and decrease of assistance from the international community, forcing IGN to stop its activities of geospatial information development, which had ceased for a long time since then.

IGN requested the Ministry of Public Works and Transport for organizational enhancement, i.e., increase of personnel and purchase of equipment. Whereas our preliminary study in February 2012 confirmed 23 staff members at IGN, the number of staff had increased to 36, with an addition of 13, as of June 2016 as shown in Table 1-1. At the start of this Project in November 2012, the IGN office did not have any office furniture or machines such as computers. However, as part of the Guinean Government’s assistance to this Project, the superannuated office was relocated in October 2013, and all the 13 office rooms came to be equipped with office desks, air-conditioners, and computers. The IGN personnel who did not use to have an adequate working environment returned to the office, significantly increasing the time for communication that can be used for meetings and discussions. Since materials and equipment for surveying and topographic mapping were introduced in this Project (see Table 3-2 for details), the operation environment of C/P is gradually improving.

1.5 Establishment of Joint Coordinating Committee

In this Project, a Joint Coordinating Committee (JCC) consisting of members of relevant authorities with usage needs was established to promote utilization of geospatial information. During the implementation period of this Project, JCC had meetings three times, on December 13th, 2012, November 21st, 2013, and May 10th, 2016 to exchange opinions and had discussions on how to supply geospatial information, appropriate information disclosure for Guinea, and how to utilize geospatial information. For details of JCC, see Section 4.2, "Joint Coordinating Committee."

1.9 Results of the Project

This Project created 1/5,000-scale digital topographic maps and orthophotos of an area of ca. 520.79 km2 including Conakry City and its surrounding area. It also transferred to the C/P personnel the technology required to appropriately maintain and update the geospatial information including topographic maps that have been created. Furthermore, activities were carried out to promote utilization of geospatial information, such as development of an environment and wide-ranging advertising for promotion and sale of geospatial information. The Project Team carried out activities according to the basic policies set forth at the project start as shown in Table 1-8.

Before the start of this Project, Guinea had only topographic maps created more than 30 years ago. Therefore, a vicious circle existed: The topographic maps were too old to be used; No budget was allocated because they were not used; The maps were not updated because of lack of budget, equipment, and technology; and the maps became more obsolete. The outputs of this Project will provide an opportunity for generating a virtuous circle. IGN, the C/P in this Project, must recognize the completion of this Project not as a goal but as a start and permanently update geospatial information, maintain and develop technologies that have been transferred, and promote utilization of geospatial information.

Table 1-8 Results of the Project

Basic policies that have been set forth Results

Creating topographic maps that will serve as the standard for Guinea

The Project Team created topographic maps that will serve as the standard for Guinea in collaboration with the C/P, using the items in the legend of the 1/5,000-scale topographic maps provided in the "Survey International Specifications (for Base Maps)” (Japan International Cooperation Agency, December 2006) to be referenced in geospatial information development projects implemented by JICA and the “Standard Map Symbols and Standard Classification of Measurement of Digital Topographic Map Data in Public Surveys” (published by the Ministry of Land, Infrastructure, Transport and Tourism of Japan) to be referenced in Japan, based on experience and knowledge acquired in similar projects implemented by the Project Team in various countries.

Realizing an environment that facilitates sharing of topographic information for everyone

The Project Team held JCC meetings and gave seminars to inform the relevant authorities of the supply method, selling prices, and examples of utilization for geospatial information created in this Project. Furthermore, the seminars were advertised on TV and in newspapers to inform the Guinean people of this Project and geospatial information. At the seminars on utilization, a simple map of Conakry City was given away free of charge to the participants and a special sale of the "Simple Map of Conakry City" and "1/5,000 Topographic Map Booklet (A3 Size)" was conducted as a means for creating an environment for promotion.


Final Report

17

Basic policies that have been set forth Results

Transferring the basic technologies for ensuring prolonged use of topographic maps

The Project Team transferred basic technologies for creating and updating data using open-source GIS software that can be used by anyone with a focus on allowing the C/P to update on its own the geospatial information created in this Project.

Carrying out the fieldwork in consideration of regional characteristics

The Project Team planned and implemented the fieldwork in a period other than the rainy season to avoid risks. Although the security became unstable due to an election of the National Assembly during the project implementation period, the Project Team shared safety information with the Japanese Embassy in Guinea and the JICA Senegal office and implemented this Project without accident.

Coordinating between JCC members carefully

JCC meetings were held at the beginning, middle, and end of this Project to discuss the objectives and progress of this Project and how to utilize the geospatial information in Guinea from now on and share the ideas of the JCC members.

(2) Map Symbols Regulation

For creation of a map symbols regulation, the Project Team prepared its proposal on the map symbols regulation using the items in the legend of the 1/5,000-scale topographic maps provided in the “Survey International Specifications (for Base Maps)” (Japan International Cooperation Agency, December 2006) and the “Standard Map Symbols and Standard Classification of Measurement of Digital Topographic Map Data in Public Surveys” published by the Ministry of Land, Infrastructure, Transport and Tourism of Japan and based on the case study on the map projects of equal scales implemented in the African countries (such as Mauritania and Burundi). Then, the Project Team discussed with the C/P to modify the proposal into standard specifications with the contents appropriate for the conditions in Guinea (including segmentation of mangrove vegetation) and received an amended draft (Figure 2-4) from the C/P. Next, the Project Team discussed matters that needed to be clarified in the draft with the C/P and finalized the map symbols regulation (Figure 2-5). The map symbols regulation is attached at the end of this Report.

2.2.2 Collection and Sorting of Existing Materials [Work in Guinea]

The Project Team collected the following materials and information related to this Project such as existing topographic maps and leveling results of existing benchmarks.

(1) Existing Benchmarks

The Project Team collected copies of leveling results of existing benchmarks. Eighteen benchmarks were selected for their relevance to the work in this Project from all the existing benchmarks, and the Project Team confirmed the locations of them in the presence of the personnel of the C/P and used twelve of them for control point survey and leveling.

(2) Existing Topographic Maps

The Project Team confirmed the scales, numbers, creation dates, and creating organizations of topographic maps created in the period between the late 1920's and the 1980's as shown in Table 2-5. These topographic maps were used as basic data for work area details check, aerial photography plan, and field verification.

The Project Team also borrowed from the C/P the 1/5,000 and 1/10,000-scale simple topographic maps created by the National Geographic Institute (Institut Geographique National France: IGN France) in the 1980's. The 1/10,000-scale simple topographic maps, which were found to indicate the names of major roads, were used as supplementary materials for road names, etc. in field verification.

2.2.3 Control Point Survey [Work in Guinea]

(1) Outline of Work

The control point survey is carried out to establish relationships between points in the photographs and the coordinates on the ground in aerial triangulation or digital plotting operation. The survey refers to installing points (control points) on the ground and observing the points that have been installed to acquire accurate coordinates of them.

In this Project, 24 control points were surveyed according to the schedule shown in Table 2-6. The work was carried out by four teams, each consisting of a C/P survey engineer, assistant survey engineer, interpreter, and driver. Since this work was also part of technology transfer efforts, two project members accompanied each of the teams as required and provided guidance and supervision on the work procedures.

The outputs prepared in this work are aerial marker details registers, control point survey results, a control point network map and an accuracy control sheet.

(2) Reconnaissance, Point Selection, and Installation

The work teams conducted field reconnaissance and selected control points. Specifically, the approximate positions of the selected control points on the plan map were identified in the field using handy GPS receivers. A control point was established at locations where an object could be easily interpreted on an aerial photograph.

As a control point is used as a reference point for horizontal positioning in the aerial triangulation, the position of its center was marked with a nail or a pin. As it was also used as a reference point in the surveys in subsequent stages of the work, it was reinforced by a concrete cast around it for prolonged use.

(3) GNSS Observation (Static Positioning)

The work teams established a GNSS observation network consisting of a total of 24 control points including a stationary point required for the aerial photography (No. 15) and implemented the GNSS observation (static positioning). The observation was carried out by four teams simultaneously at four control points using less than the baseline length x 5 ppm as the standard for the observation accuracy.

(4) Long Baseline Interferometry and Analysis

To establish the origin of control points in Guinea, the work teams carried out long baseline interferometry (GNSS observation) on two of the control points (No. 2 and No. 18) continuously for 48 hours (from 10:00, November 29th to 10:00, December 1st, 2012).

Long baseline analysis was carried out using the data obtained from the above-mentioned observation and the data of the IGS (International GNSS Service) points in neighboring countries to determine the latitudes and longitudes of the control points in the World Geodetic System (WGS).

(2) Selection of Benchmarks

The Project Team created a leveling route plan map shown in Figure 2-10. Benchmarks (BMs) required for the implementation of the aerial triangulation as reference points of elevation were selected at approximately every 3 km along the leveling routes on this map.

The positions of the BMs were, in principle, at locations where the objects could be clearly interpreted on aerial photographs and marked with paint on the ground.

BM registers were prepared and used as reference materials in the aerial triangulation.

Photo 2-9 Existing National Benchmarks

(3) Leveling Observation

After confirming the accuracy of the elevation values of the existing BMs by conducting inspection leveling between the existing national BMs, the Project Team implemented simple leveling along each leveling route. Leveling observation was started from the existing national benchmarks as reference points and elevation values were provided at the control points (GNSS observation points). The accuracy of the simple leveling was 5 cm √S (where S is the distance between two observation points) according to the Survey International specifications of JICA.

(5) Quality Control of the Aerial Photographs

Immediately after the aerial photography, the images were printed (in the form of Rush Prints) and the printouts were inspected for quality control. Specifically, the printouts were inspected for halation, cloud, mist and shadow cover, overlap ratio and complete acquisition of all the images in the entire photography area. A second round of photography was conducted in certain areas for which the photographs did not meet the specifications. Finally, complete acquisition of all the images in the entire photography area was achieved. 2.2.6 Aerial Triangulation [Work in Japan]

(1) Outline of Work

Aerial triangulation refers to measuring coordinates of pass points2, tie points3, control points, etc. on the photographs using a stereo plotter and conducting adjustment calculation by integrating control point survey results and positional information of principal points on the photographs in order to determine the output values of the positional information of principal points on the photographs and the horizontal positions and elevations of pass points, tie points, etc.

The Project Team implemented aerial triangulation based on digital aerial photograph data acquired in the aerial photography and GNSS/IMU data according to the workflow shown in Figure 2-13.

4) Automatic observation of pass points and tie points

Automatic observation of pass points and tie points was conducted using the image matching technology of digital photogrammetry.

5) Inspection of control points, pass points and tie points

Automatic observation was conducted using the generation parameter which was appropriately set for the photography area, followed by visual inspection.

6) Adjustment calculation Block-by-block adjustment calculation was conducted using the Bundle adjustment4. After the calculation, residual errors of the control points were checked. If a problem existed, the work in Item 4) was repeated. Finally, we ensured that the results were within the permissible range specified in the relevant operation criteria in the Survey International specifications of JICA. At the same time, we checked that there was no parallax between the models or courses using stereoscopic views.

(3) Summary of Aerial Triangulation Results

The exterior orientation element5 data required for the subsequent digital plotting (coordinates: Px, Py and Pz, and angles of rotation: omega, phi and kappa) were calculated and verified. Furthermore, the exterior orientation element data were expanded into an aerial triangulation orientation map.

Tie point measurements and adjustment calculations were prepared as the outputs of the aerial triangulation. 2.2.7 Creation of Orthophotos [Work in Japan]

An orthophoto is created by acquiring an aerial photograph with central projection and processing it with orthogonal projection to correct distortions using elevation information.

Based on the specifications shown in Table 2-14, the Project Team created orthophotos by creating stereo models from the data of digital aerial photograph images and the aerial triangulation outputs, creating DEMs with 20 m grid spacing, and correcting distortions in the digital aerial photos.

2) Preparation of the Map Symbols Regulation for Field Verification Since the map symbols regulation was not finalized as of March 2012 at the start of the field

verification, the project members prepared in Japan a draft map symbols regulation to be used for the field verification.

3) Formation of Work Teams Three project members and 13 C/P personnel were divided into seven work teams (two teams

of project members and five teams of C/P personnel). One of the formed seven teams was assigned to the vegetation survey work. Until the completion of the vegetation survey, the remaining six teams surveyed the topography and planimetric features. After the completion of the vegetation survey, all the seven teams continued the survey on the topography and planimetric features.

One C/P personnel other than the field verification workers took charge of digitizing the annotation data.

(3) Implementation of Vegetation Survey

1) Preparation of the Draft Handbook on Interpretation Keys The handbook on interpretation keys was prepared to achieve accurate and uniform photo

interpretation by the photo interpreters and operators in the subsequent digital plotting. Each photo interpretation key was selected from the items in the “Map Symbols Regulation (draft)” and “vegetation” was included in the subjects of the interpretation.

The subjects were selected from the items in the “Map Symbols Regulation (draft)” and included “forest,” “scrub,” “afforested area,” “open and felled forests,” “wooded savanna (shrubs on grassland),” “cropland (ordinary fields)” “wetland cropland,” “cropland (rice paddies),” “green areas,” “mangrove forests 1,” “mangrove forests 2,” “rocky land,” “sandy land,” “laterite land” and “plantation.” Segmentation of mangrove was conducted because mangrove is important in characterizing the Guinean vegetation. As there was no “tropical rain forest,” “savanna,” “pasture land” or “baobab forest” in the area for creating topographic maps, they were excluded from the subjects of the preparation of the handbooks on interpretation keys.

2) On-site Verification of Interpretation Keys and Completion of the Handbook

The field verification teams compared vegetation to be used as interpretation keys and orthophotos in the field to check how each of the vegetation types is represented in the orthophotos. The field verification teams recorded the characteristics of each vegetation type in the reconnaissance report, took photographs of the vegetation types in the field and incorporated the data obtained in the reconnaissance in the handbooks.

3) Photo Interpretation The handbook of interpretation keys was used in photo interpretation of the vegetation.

Different types of vegetation coexist in dense mangrove forests (in the central and northwestern parts of the study area), areas where there are many plantations (east of the central part) and lateritic mountainous terrains (in the northeast), in particular. Therefore, the interpretation of these areas was implemented with care.

Figure 2-18 Example of a Photo Interpretation Sheet (on an area with many plantations)

(4) Implementation of Survey of Topography and Features

1) Collection of Information from the Relevant Materials The administrative boundaries, operational statuses of railway lines, topography and

planimetric features, and names of roads were checked and recorded using the 1/50,000 and 1/10,000-scale topographic maps borrowed from the C/P.

2) Preparation of the Map Symbols for Field Verification

Based on the draft map symbols regulation prepared by the project members in advance, the C/P personnel and the project members discussed what needs to be clarified or verified and necessity of additional items and created the map symbols regulation for field verification to be used as basic data for the field verification work.

3) Survey of Topography and Features (On-site Verification)

The field verification was conducted on all the topography and planimetric features which could not be interpreted by the operators in the photo interpretation and the plotting. For public facilities and landmark buildings, the exact locations as well as the names (annotation information) were verified.

GPS-enabled digital cameras and handy GPS receivers were used effectively in the verification. If the C/P personnel had any data requiring clarification or verification, they consulted a Japanese engineer on the matter when they marked the data acquired in the verification. All the verified matters were marked on the field verification sheets by completion of the field verification.

4) Recording and Digitization of Annotations The locations of the annotations collected in the on-site verification and from the reference

materials were described clearly on the field verification sheets. The details and codes of the annotations were entered in the data sheets. One C/P personnel used this information to digitize the annotation data (in the office). Symbols were used in principle in built-up urban areas while annotations were used mainly in the suburbs. In principle, no feature was to be represented by both a symbol and an annotation.

The digitized annotation data was carefully checked by all the field verification team members for entry errors and omissions.

(5) Compilation of the Field Verification Results

During the period of field verification, the C/P personnel and the project members collaborated to mark the results of field verification on two designated data marking days every week. Finally, the field verification outputs were prepared as shown in Table 2-16.

2.2.9 Digital Plotting and Digital Compilation [Work in Japan]

(1) Outline of Work

The Project Team implemented the digital plotting and digital compilation work according to the workflow shown in Figure 2-20. CAD software was used for the digital plotting and digital compilation work.

(2) Digital Plotting

Digital plotting refers to creating stereo models from the results acquired in aerial photography and aerial triangulation using a stereo plotter, acquiring coordinates of topography and planimetric features, and creating digital plotting data.

The data were obtained on the shapes and locations of planimetric features as graphic data using the results of the field verification as reference and the digital plotting data (of the 520.79 km2 area) were created with those data. For each graphic data, the Project Team classified and entered the attribute information such as planimetric features by class (feature type) and data type according to the data measurement items and standards for the plotting set forth in the map symbols regulation.

(3) Digital Compilation

Digital compilation refers to creating digital compilation data by connecting the line data, creating polygon (plane) data, and carrying out data cleaning on the digital plotting data, including removal of unnecessary data, in accordance with the results of the field verification, etc. and by adding data on the administrative boundaries and annotations to the digital plotting data. During this process, edge matching of planimetric features on adjacent map sheets is confirmed.

The matters to be clarified or verified (for omissions and errors) in the results of the field verification identified in the digital plotting/compilation were entered in a “matter-to-be-clarified/verified” layer created in the digital compilation data as text data and the data in the layer were used in the field completion as reference material.

2) Formation of Work Teams

Three project members and 15 C/P personnel were divided into eight work teams to carry out this work. As the work progressed, some of the work teams were assigned to acquire uncollected materials or check the positions of transmission lines as described later.


Final Report

55

3) Collection of Relevant Materials

Materials regarding the positions of administrative boundaries, aqueducts, etc. shown in Table 2-18 were collected via the C/P from the relevant authorities.

The railway information and other materials collected in the field verification were rechecked by the C/P. The points to be corrected, as well as the field completion results, were incorporated in the digital compilation process after field completion.

Table 2-18 Collected Information

Information Collection results Information on national borders and administrative boundaries

The administrative boundary data for the Conakry Special Zone, Kindia Region (administrative boundaries [prefectural and commune boundaries] of Dubréka and Coyah Prefectures) was prepared based on the “Administrative Boundary Data” acquired from the National Statistical Institute and existing topographic maps. The prepared administrative boundary data was checked and approved by IGN.

Positional information for aqueducts

The positional data acquired from SEG (Société des Eaux de Guinée) with regard to the aqueducts extending from Kindia was checked by the C/P and excluded from use because there is doubt in accuracy.

Positional information of transmission lines

The Electricity of Guinea (Electricité de Guinée: EDG) confirmed that, in Guinea, there are high-voltage lines of 60 kV and 110 kV and low-voltage lines of 20 kV (see Figure 2-24). (There is also an installation plan for 225 kV high-voltage transmission lines, which were not covered in this Study). The map of the middle-voltage transmission line network was acquired from EDG and used as material for on-site verification work. Since most of the pylons and high-voltage transmission lines were identified in the photo interpretation, only obscure points were checked in the subsequent verification work.

(3) Field Completion Work

1) Explanation of Work Procedure On the first day of the field completion work, all the C/P personnel who would carry out this

work were briefed about the work details based on the work manual prepared by the project members in Japan. After explanation, the Project Team worked with the IGN personnel in the field on a trial basis in an effort to deepen the understanding of the work details.

2) Check of Field Completion Details (Creation of Verification List)

The field verification results (field verification sheets) and field completion maps were compared to check that the field verification results had been reflected and that there were no errors (typos) in plotting results, annotations, etc. If there was any problem such as an error or omission, a correction instruction for it was written on the field completion sheet.

Photo 2-18 Preparation for the Field Completion Work

3) Field Completion Work

The matters to be clarified or verified were clarified and verified at approx. 1,400 points (93 maps) in the field. The target planimetric features were checked for the positions, ranges, forms, names, and classifications (code numbers) based on the verification list prepared by areas corresponding to map sheets. The verification results were written on the field completion maps with comments while referring to the Map Symbols Regulation.

4) On-site Verification Work on Transmission Lines (High and Middle-voltage Lines)

The middle-voltage lines were checked with regard to accurate positions of the transmission lines based on a network map obtained from EDG. Although there were considerably more middle-voltage transmission lines than on the network map due to changes through time, all the lines were verified. However, it was difficult to conduct verification in the central area of Conakry City because all the middle-voltage transmission lines were buried underground. Therefore, the Project Team obtained approval of the C/P and acquired an underground installation plan for new middle-voltage transmission lines to be buried and conducted the

verification based on this material. The high-voltage transmission lines were verified on-site with regard to positions of

transmission lines and pylons based on the results of interview survey at EDG and photo interpretation by operators of digital plotting and digital compilation.

(4) Marking of the Field Completion Results

In principle, the results of field completion were marked in the field. However, the C/P personnel and the project members marked the results of the field completion on two designated data marking days every week, while discussing matters that were difficult to evaluate. Finally, the field completion outputs were prepared as shown in Table 2-19.

completion was used to conduct symbolization.

Figure 2-27 Map Symbolization

2.2.13 Digital Data Structurization and Creation of Data Files [Work in Japan]

Using the topographic map data created in the digital compilation after field completion, the Project Team conducted the structurization of digital data to create data usable for GIS based on the settings determined in the Discussion on Specifications (number and details of layers to be grouped during CAD data format conversion). Furthermore, the GIS data created in the structurization was converted to create data files in the "Shape-file format," a data format with a structure that is user-friendly and highly versatile.

2.2.14 Preparation of Booklets, etc.

Based on topographic map data created in this work, the Project Team prepared booklets and simple maps listed in Table 1-6.

2.3 Proposal on Creation and Update of Topographic Maps

The collaboration between the Project Team and the C/P created new digital topographic maps and orthophotos for Guinea after about 30 years. Although the project is complete, the C/P must serve as an organization that manages and maintains geospatial information by updating these topographic maps whenever possible and keep them in an excellent condition.

Update of topographic maps needs technologies (personnel), materials and equipment, and budgets and must be conducted on a planned basis. The Project Team proposes to the C/P to establish a plan for


Final Report

62

updating topographic maps as soon as possible. The major items to be considered in establishing a plan are described below.

Update cycle

The update cycle must be determined while keeping the balance between securing of budget and personnel and statuses of changes in the mapping area. For example, the Geographical Survey Institute of Japan updates the basic map information, the fundamental information on planimetric features such as roads and rivers, four times every year (January, April, July, and October). Furthermore, it handles digital topographic maps differently: The geospatial information is updated promptly (whenever required) upon occurrence of a wide-area change in the topography and planimetric features or construction of highways, national roads/bypasses, railways, and large buildings. However, the update procedure requires considerable cost and labor. Considering the status quo of Guinea and the capacity and financial conditions of the C/P, it seems appropriate in Guinea to update geospatial information once every three or four years as a guideline and conduct partial update in relation to significantly changed parts.

For example, a case shown in Figure 2-28 may be subject to partial update. Figure 2-28 shows images of the same points (area around the three-way junction on National Roads 1 and 3) in 2012 and 2016, showing a significant change in the road shape. At the time of technology transfer described later, the Project Team provided a lecture and training on the update method to be used for such a change in a planimetric feature.

December 2012 (aerial photograph taken in

this Project) March 2016 (Google Earth image)

Figure 2-28 Example of Change in a Road (Area around the Three-way Junction on National Roads 1 and 3)

Update targets Update targets must be determined in advance because necessary materials and equipment,

budget, and personnel differ depending on what is to be updated. An area without a topographic change is expected to be updated relatively easily because only flat-plane planimetric features need


Final Report

63

to be updated. If a topographic change such as excavation is involved, however, the elevation information must also be updated. If it is difficult to update all the information every time, different update cycles may be specified for different update targets.

System of update The departments in charge of the work processes for update, such as securing of budgets, update

procedure, and notification to users, must be determined in advance to ensure smooth progress of the work processes upon arrival of the due date for update. In particular, securing of budgets is extremely important and requires time, the departments in charge must have a meeting at least one year before the due date for update to check the details of update work and necessary materials and equipment, estimate the budgets, and consult with MTP, the upper organization. Furthermore, the departments in charge of the update process must coordinate the daily duties of the personnel to be engaged in this process to allow sufficient time for the update process during the period for it.

Update method If the update cycle is every several years, the personnel in charge may be transferred in the

meantime. Therefore, the update method must be recorded in documents in detail based on the technology transfer contents and work manuals prepared in this project in order to maintain the capacity despite transfer of personnel. The data to be used for the update process can be satellite images and field survey results but must be considered each time according to the scales of the budget and update process.

Notification to users It is desirable to inform in advance the users of two of the above items, the update cycle and the

update target, as a “plan for providing geospatial information. ” This procedure can both motivate the C/P to periodically update the geospatial information and assure the users that the information currently used by them will be updated appropriately. Consequently, this procedure is expected to further promote the availability and utilization of the geospatial information.

3.2 Technology Transfer Contents

3.2.1 Control Point Survey and Simple Leveling

(2) Evaluation of Technology Transfer

Before the implementation of this Project, the Project Team estimated that the C/P personnel could use only fundamental-level technologies because they had lacked experience in basic work procedures such as those for using the equipment to be used in this Project. However, the participants, in general, have understood the transferred technologies well, partly because the technology transfer concerned the survey equipment used in the C/P's area of specialty, despite some difference in the level of understanding among the personnel.

All the participants successfully learned the technologies selected as key points for technology transfer as well as how to operate handy GPS receivers and GPS-enabled digital cameras. The Project Team appreciates the fact that the control point survey/simple leveling was completed within the planned work period (of 60 days).

This technology transfer served also as the human resources development based on the recognition of the types of engineers, “leader-type, craftsman-type, and young members.” The C/P has a well-balanced composition of these types of personnel. In this organization, therefore, knowledge and technologies learned in the technology transfer are expected to be disseminated and inherited.

3.2.2 Field Verification

(1) Details

The technologies used in the series of work in preparation for survey, field verification, and marking of verification results were transferred through lecture and practice.

This technology transfer was implemented with a focus on the issues listed below and in a phased manner in the order of “Lecture on the purposes of and activities in field verification, trial verification with all the participants, trial verification in tentative teams, and actual process for creating topographic maps in the field (March to April 2013).” After the start of the field verification, the project members provided the participants with OJT by accompanying different teams every day and providing them with advice on the verification method and work procedures in an effort to brush up their technologies.

[Key Points in Technology Transfer on Field Verification] To understand the purpose of the work, role and necessity of field verification in the overall

workflow and the items (map symbols) to be verified To acquire the ability to interpret photographs and the capacity to match objects on the ground

with those on the photos To learn how to mark locations, shapes, names, etc. of planimetric features on the photos To understand the importance of quality control (process control and inspection/verification of

unverified items, code mismatches, edge matching between map sheets, erroneous entries and missing letters)

To understand operation methods for GPS-enabled digital cameras and handy GPS receivers (review of technology transfer contents in control point survey and application of them to field verification)


In the early stage of the field verification, there was inconsistency in the work procedures and photo interpretation (object matching) between different teams, slow progress of the work and cases of interpretation errors and misunderstanding. However, the participants were able to solve these problems in a short period of time because they had experience as survey engineers, which they had acquired in their work, and instruction and advice provided by the accompanying project members.

One participant was unable to attend the technology transfer because of sickness. However, his place was immediately filled by another person. Therefore, the work continued smoothly without a hitch. The Project Team considered that the C/P personnel who participated in the technology transfer in the field verification understood its contents sufficiently. They continued to implement the verification activities without taking extra breaks on hot days. The Project Team highly appreciated such dedication to the work shown by the participants.

(1) Details

The technologies used in the series of work including preparation, field completion, and marking of field completion results were transferred through lecture and practice.

This technology transfer was implemented with a focus on the issues listed below and in a phased manner in the order of “Lecture on the purposes of and activities in field completion, trial completion with all the participants, and actual process for creating topographic maps in the field (November to December 2013).” In the lecture, the creation of an “accuracy control sheet” was introduced as a technology control method currently used in Japan. After the start of the field completion, the project members provided the participants with OJT by accompanying different teams every day and providing them with advice on the completion method and work procedures in an effort to brush up their technologies.

The implementation of the technology transfer through a lecture and OJT in stages is considered to have led to the improvement of understanding of the field completion among all the participants. Many C/P personnel also participated in the technology transfer in the field verification so that few interpretation errors and erroneous entries were observed.

The technology transfer of field completion is considered to have been completed upon achievement of the objective because the participants conducted the marking activities without problems and had high understanding about the explanation of the accuracy control sheet.

Almost all the participants participated in the entire technology transfer without fail. They continued to implement the completion activities without taking extra breaks on hot days. The Project Team highly appreciated such dedication to the work shown by the participants.

The technologies related to “outline of creating topographic maps,” “basics of GIS,” and “partial revision of topographic map data” shown in Table 3-4 were transferred in three stages in December 2013, July 2014, and May 2016 through lecture and practice.

Before technology transfer, a questionnaire was sent out to the participants to identify their status quo. The questionnaire included questions on their knowledge and skills such as “professional career, understanding of creation of topographic maps, understanding of survey criteria (such as reference ellipsoid, map projection, and scale) and experience of computers and GIS.” The details of the lecture were arranged in view of the result of this questionnaire based on the policies of technology transfer.

1) Outline of creating topographic maps

The Project Team delivered lectures on the entire workflow for creation of topographic maps in terms of a common workflow, work procedure in each of the processes, and contents of data to be created. Lectures were also given on the fields in which the created data can be utilized. In particular, explanation was focused on “why this stage is required” for each process.

This subject was covered every time the technology transfer was conducted in December 2013, July 2014, and May 2016 to provide the participants with opportunities for review.

2) Basics of GIS

GIS, which is used to handle geospatial data, is an essential tool for the C/P because the geospatial data to be created from the topographic map data offers high expectations for utilization in the future. Therefore, the basic concepts and application examples of GIS were explained.

Concerning the mutual use of geospatial data, the Project Team explained that the C/P personnel would play a leading role in the future regarding topographic maps and GIS because there would be higher demand for maps and necessity for GIS when the information was shared with the relevant authorities and private companies such as the electricity and water service that needed maps.

3) Installation and basic operation practice for open-source GIS software “QGIS”

After understanding the outline of GIS, the participants deepened their understanding through practice by actually using GIS software. Using the topographic map data created in this Project and various information, explanation was given on how to create and process data and use it with GIS.

The software used in this practice was QGIS, open-source software without limitations on use due to licensing, etc. Three desktop PCs purchased in this Project were used by three teams into which the participants were divided (laptop PCs were used if any of them malfunctioned).

(b) Revision method using devices such as handy GPS receivers

Apart from a method using image data, another method that the C/P can employ immediately is to update topographic maps according to the result of field survey on changes using handy GPS receivers.

Therefore, the Project Team provided practice on updating topographic map data, assuming a situation of “construction of a new building in front of the IGN office.”

(1) Finding coordinates of corners of the building using handy GPS receivers (2) Loading the data into the GIS software (3) Overlapping the data with the map data and revising it

Although the coordinates found using the handy GPS receivers were not accurate enough to

be applied to the 1/5,000 map data, they were used in the explanation and practice to show one of the ways to utilize equipment and materials currently owned by the C/P.

(c) Plane-table survey In July 2014, the Project Team provided explanation and practice on plane-table survey

equipment to six C/P personnel at the C/P project office. The plane-table survey is a long-used basic technology for creating maps but is now used

less often because of technological innovation that promoted the use of digital equipment. In Japan, however, this is a technology that must be learned by anyone who wants to become a professional surveyor.

In this Project, technology transfer on the plane-table survey was conducted with an aim of transferring a basic technology for creating maps and learning one of the methods to be used for partial revision.

Brief lecture was provided on the workflow including a survey plan, field verification, observation, calculation process, and creation of topographic maps. Then, the Project Team explained that the topographic survey conducted to create topographic maps used to be plane-table survey but has been replaced with photographic survey by now. Furthermore, the Project Team explained the names and operations of the plane-table survey equipment (plane table, tripod, alidade, plumbing arm, plum bob, and surveying pin) that were used in the past and also showed how to use these devices specifically.

Photo 3-8 Explanation Given by Project Members Indoors on Plane-survey Equipment

The practice was conducted in three teams on three dummy control points installed on the premises of IGN to achieve a goal of creating a map of the IGN premises by plane-table survey. The participants assembled a plane table and a tripod, set them on a dummy control point, made them level using an air bubble in an alidade, matched the point on the plane table with the ground control point using a plumbing arm, and aligned it to the other control point using the alidade.

One team consisted of an observer, a poleman (person who set a pole on the object), and a person who measured distances using a measuring tape and plotted house corners, fence ends, and gateposts on paper on the plane table according to distances and directions. Then, these points are connected with lines to create a topographic map. The Project Team demonstrated how to handle equipment, explained the division of roles among the surveyors, and provided hands-on practice for half a day.

(d) Map symbolization and creation of map layouts Just after data is loaded, data is expressed only as one of the single symbols of line, point,

and plane. Therefore, the Project Team provided explanation and practice on two methods to realize expression as a topographic map: (1) expressing with symbols the data according to code numbers assigned to data (map symbolization) and (2) expressing numbers and characters contained in data as attribute values. Then, a map layout was created while displaying legends, a bearing mark, and other elements.

During the practice on map symbolization, the Project Team did not specify any specific symbols but each of the teams was allowed to use any symbols of its choice so that the participants could learn from experience that symbols were defined on software. A map layout was also created by each of the teams. Figure 3-8, Figure 3-9, and Figure 3-10 show the maps created by each of the teams. Although each of the teams used different colors, the maps show that all the teams successfully completed map symbolization and created map layouts based on the explanation that they were given.

(e) How to operate the plotter The Project Team provided explanation and practice on how to use the large plotter

introduced in this Project. The contents of this process are as follows: (1) Power-on (2) Operating the menu screen (3) Setting paper (4) Connecting the plotter to a PC (5) Printing sample data (PDF)

First, the project members explained and demonstrated the operations and then the

participants tried out the above items (1) through (5), with half of them taking turns each time. During this time, the participants conducted the operations while explaining to other participants what they were about to do (for example, set paper) and, for this purpose, which function they would select in the menu screen. Meanwhile, the project members observed how the participants conducted the operations to check their level of understanding. They did not ask the project members any particular question but completed the series of operations while consulting with each other.

(f) Printing of maps There are two ways to print a created map: (1) printing it directly from the GIS software

and (2) converting it into PDF format first and then printing it. Since the method to print a map in PDF format was demonstrated during the explanation

on how to operate the plotter, this practice session provided explanation and practice on how to print a map directly from the GIS software.

Photo 3-12 Practice (Printing a Map)


During the technology transfer conducted indoors, the project members explained and showed actual operations using a projector to all the participants. Throughout the explanation by the project members, all the participants seriously watched the images projected on the screen and took notes without uttering a word. The participants made such serious efforts in the technology transfer that, when they did not understand anything in the explanation, they immediately asked a question to request for further explanation.

To check the understanding of this technology transfer, the Project Team gave a check test about creation of topographic maps and GIS (total of 25 true-or-false questions) shown below on the final day. The check test was taken by five of the seven participants of the technology transfer (two of them were absent because of family circumstances).

[Check test] 1. No plan or preparation is needed to create topographic maps.

2. Map symbols are not needed to create topographic maps.

3. If only 1/5,000-scale maps are available, maps of other scales are not needed.

4. The order of operations for creating topographic maps is as follows: Plan => Control point survey and leveling => Aerial photography => Field verification => Digital plotting => Aerial triangulation => Digital compilation => Field completion => Digital compilation after field completion => Map symbolization => Completion of topographic maps.

5. DSM (Model de surface numérique) and DEM (Model de terrain numérique) mean the same thing and do not have any difference.

6. Field verification is not needed for the areas under trees because they are not visible in photographs.

7. Mapping compilation is conducted based on the Map Symbols Regulation and field verification results.

8. Field completion is not needed if no problem or unclear point is encountered in the mapping work.

9. Structurization is the processing needed to create data for GIS.

10. You need to collect various information in collaboration with other agencies in order to promote utilization of maps and GIS.

11. In GIS, you can handle various information that cannot be handled in analog, paper-based maps.

12. In GIS, you can combine maps and attribute information to change colors and search for information.

13. The shp file consists of several files but two of them are important.

14. The map projection setting used for the road layer of Conakry City was WGS84/UTM28 S.

15. In GIS, you can display in a label the attribute information stored in a graphic form.

16. When you load raster data into GIS, it is displayed. Therefore, you can proceed with the work without setting the map projection method.

17. One control point is sufficient for georeference of raster data.

18. A tfw file that comes with tif data is not necessary and therefore you delete it.

19. There are three types of vector data: points, lines and polygons.

20. You connect lines without using the Snap function.

21. IGN is an organization that manages geospatial information of Guinea but need not update maps after they have been created.

22. No map is needed to develop infrastructures (such as roads, railways, water service, and electricity).

23. You need not share with other persons the technologies and knowledge that you learned on your own.

24. The original topographic map (GIS) data must be stored away properly and must not be directly used.

25. The GIS data is required for urban planning.


Final Report

The scores of this check test out of 100 points (four points each for one question) were 92 for two

persons and 84, 80, and 68 for one person each. This result shows that the participants understood most of the contents of the lecture. Supplementary explanation was provided about wrong answers in the check test and matters related to them in order to clear up the participants’ misunderstandings.

The practice of GIS operations was proceeded with while checking step-by-step the understanding and acquisition of basic operations as required until, finally, all the participants were observed to achieve the specified objective of this practice.

Although the plane-table survey is a basic technology for creating maps, the Project Team was initially afraid that the C/P personnel might not be interested in it because this survey method is used less often now. However, they were able to realize that, as the work progressed, the shapes of houses, fences, and gates were drawn one after another and began to form the appearance of a map. Therefore, they became better motivated and more interested in the practice as the work progressed. The electrical power conditions in Guinea are not so good. If more digital equipment begins to be used and more electrical power (such as batteries) is needed, there may be circumstances in which the C/P personnel may need to depend on this analog method.

The Project Team highly appreciates the participants’ attitude to learn with willingness in this technology transfer. Some of the participants spontaneously reviewed during recess what had been learned and even wanted to extend the practice time beyond the initially planned end. Despite the environment in which there was no electricity, they said that they wanted to continue practicing spontaneously in the future.

As the evaluation of this lecture and practice, the Project Team admires the participants’ high motivation and good results of the check test and hopes that they will continue to have the same high motivation in pursuing the acquisition of technology in the future.

3.3 Proposal on Technology Transfer

The Project Team transferred the technologies for basic surveying and creation/revision of the digital topographic maps in order to allow the C/P itself to maintain and update the digital topographic maps created in this Project. Since the objectives specified for each of the technologies to be transferred were achieved as described above, the Project Team considers that the C/P mostly acquired the target capacities. However, the technologies transferred in this Project are only basic ones. When the C/P actually updates digital topographic maps after completion of this Project, it is expected to encounter various problems and difficulties. Furthermore, any technology or knowledge will be forgotten sooner or later unless the C/P personnel keep daily contact with it and use it continuously. It is one of the Project Team's concerns that they do not have opportunities to immediately use in their work duties many of the technologies that have been transferred in this Project. Furthermore, the C/P must consider not only brushing up the technologies of its personnel who participated in the current technology transfer but also providing training to new personnel to be assigned to this organization.

To address these issues, first the C/P personnel who participated in the current technology transfer must examine and consistently make the efforts required to maintain and improve their technical capabilities.

Specifically, for example, they can hold technical study meetings or research paper reading meetings (conducting case study on latest examples in other countries) and carry out activities for sharing new knowledge and experience that they have acquired. Alternatively, all of the C/P personnel can meet, for example, once a year and conduct the same practice as in the technology transfer to prevent forgetting the acquired technologies.

The Project Team confirmed through the technology transfer the C/P has a strong enthusiasm to acquire the technologies. These activities will provide good opportunities to maintain their enthusiasm and brush up the knowledge and skills that they acquired in this Project. It is expected that they will become trainers and the C/P itself will continue to improve its technologies and develop human resources in the future.

The social infrastructures of Guinea are not sufficient by any means. There are difficulties that the C/P cannot overcome by itself, such as unstable supply of electricity that is required to update the digital data that has been created in this Project. However, the project members told the C/P personnel time and time again that it is exceedingly important for the C/P to brush up the acquired technologies by itself to maintain and improve them for the sake of sustainable development in the future. The project members hope that the C/P personnel will remember this point in carrying out the work duties in the future.

Chapter 4 Promotion of Utilization

4.1 Activities for Promotion of Utilization

To promote utilization of geospatial information such as topographic maps, orthophotos, and GIS data created in this Project, it is necessary to make efforts from two aspects: (1) developing various environments for supplying them smoothly and appropriately and (2) improving name recognition among users and eliciting the needs of users. Based on this approach, this Project held JCC meetings and seminars on utilization as shown in Figure 4-1.

Figure 4-1 Activities for Promotion of Utilization

4.2 Joint Coordinating Committee (JCC)

To develop an environment for supplying geospatial information such as topographic maps created in this Project, the Joint Coordinating Committee (JCC) discussed and decided on specific supply methods and selling prices based on the exchange of opinions on appropriate supply policies and utilization methods for Guinea.

The member organizations of JCC were selected according to the project instruction. However, the Survey Association, initially assumed as a candidate, was excluded because no actual activity was observed. Furthermore, the Ministry of Land Urban Planning and Construction was selected as a member according to a request from the C/P.

The following facts were revealed from the opinions of the meeting members: None of the organizations is using geospatial

information (or there is no geospatial information available).

Even if they are provided with digital geospatial information, they do not have hardware or software to browse, print and utilize it.

There is more need for printout (paper) maps than for digital maps (because of the ease of use).

IGN has no plan to create enough printout (paper) maps to distribute to the JCC member organizations.

If geospatial information is provided to them in the

form of PDF files, they cannot print the data in them, because they do not have required hardware.

(5) Future Activities of JCC

The first JCC meeting revealed that the member organizations did not have materials and equipment required for the use of digital topographic maps. The immediate task until computers have been installed in the departments requiring the geospatial information in these organizations will be provision of sufficient paper maps, in the form of either printed maps, printout maps, etc. to them.

In response, the Project Team decided to urge the C/P continuously to respond to users’ needs by: Establishing contact points (telephone number and e-mail address); Distributing copies of the 1/5,000-scale topographic map booklet (A3-sized) which is to

be created in this Project to the JCC member organizations and participants of the seminar on utilization;

Developing a system which enables printout of geospatial information with the PCs and plotters;

Securing budget for appropriate maintenance of the equipment and purchase of consumables such as ink and paper; and

Implementing activities to inform the institutions concerned of the usefulness of digital geospatial information and solicit them to use it instead of paper maps

Table 4-4 shows the major topics of opinion exchange and information and opinions provided by the meeting members.

Table 4-4 Topics and Information/Opinions of the Second JCC Meeting

Topic Information/Opinions

Matters of concern about

supply of geospatial

information

Until the beginning of 1990, IGN had Administrative and Finance Service (SAF), which sold and provided geospatial information. Later, SAF was dissolved due to financial difficulties and outdated topographic maps. Gradually, the map supply service was abolished.

There is a concern about delay in promotion of geospatial information because of limited name recognition of IGN.

Although the supply of paper-based maps requires plotter ink, paper, and electricity, no budget is available at present for purchasing consumables and fuel for generators. Since there is budget only for personnel costs, IGN is supplied with computers, air conditioners and other equipment as actual goods depending on the budget situation of the Ministry of Public Works and Transport.

An appropriate method of supply from IGN to users must be examined. When to distribute data must be examined (e.g. at the completion of the Project)

so that the geospatial information will be used by many relevant authorities.

Price of topographic

maps

The approximate annual sale of maps by IGN is 0 to 5. The study team had an interview with the Director-General who answered, “Few people purchase maps because they are outdated. They are only rarely purchased by mineral exploration companies. Since we have no stock, we ask a special shop to copy maps on A0 sheets and sell them.”

The selling price per map is GNF 175,000 (JPY 2,625), which is more expensive than in other countries.

Whether the current selling price is appropriate must be examined. There is a concern that expensive geospatial information may get in the way of

utilization promotion.

Topic Information/Opinions

Matters of concern about

licensing of geospatial

information

IGN has no experience of handling digital geospatial information so that it does not know appropriate handling and management methods.

The supply of GIS data has risks of illegal copying and data tampering. If we hesitate to supply data in fear of illegal copying, the geospatial information

may be less utilized. Setting too high a price of data may result in circulation of illegal copies. The

measures for preventing illegal copying must be examined. How digital data should be supplied to users must be examined.

The meeting discussed mainly the selling prices and supply methods of geospatial information. Since the meeting was held about two years later than initially scheduled, first the subjects of discussion at the previous meeting were informed before the discussion began on the topics this time. The following shows the items approved in the discussion.

Not printing or selling paper-based maps

The past JCC meetings revealed the following three facts: (1) The demand for paper -based maps is approximately five maps per year; (2) It is difficult for IGN to secure plotter ink, A0 paper, and electricity at all times to supply paper-based maps; and (3) The sales system of IGN


Final Report

100

has not been developed yet. Many issues must be solved to print topographic maps on a plotter. There is a concern that, if IGN announces that it can supply paper-based maps, it may not be able to supply a sufficient number of maps, falling short of users' expectations and losing their trust. Therefore, JCC decided not to start a service to print topographic maps but to supply the outputs of this Project, Simple Map of Conakry City, 1/5,000 Topographic Map Booklet (A3 Size), and digital data.

Deciding where to supply

Geospatial information shall be supplied basically at the IGN office. A person who wants to purchase the geospatial information shall send an e-mail or make a phone call directly to the director of IGN to determine the date and time for receiving it. The Simple Map of Conakry City shall be sold also at the bookstores.

Although the price of PDF Topographic Maps (supplied in DVD) has been set, the Project Team recommended the C/P to supply them free of charge, if possible, to promote widespread use of GIS data. To allow the C/P to give away the map data free of charge, the Project Team provided the C/P with 30 DVDs that contain a set of PDF Topographic Maps.

The prices of GIS data and orthophotos were set according to the ratios of mapping ranges that were calculated for each map sheet as shown in Table 4-9. To facilitate understanding by purchasers at a glance, the Project Team provided the C/P with an index map printed on a vinyl cloth 1 m by 1.5 m to display the ratios of mapping ranges as shown in Figure 4-2.

Supply of geospatial information data in operations between government organizations

The geospatial information data shall be supplied to government organizations according to the regulations and customs for operations between the government agencies. Generally, a government agency (director) shall submit an official request to the Director-General of IGN and then the two parties shall discuss the supply method, shouldering of costs, etc.

Supply methods for GIS data and orthophotos

A person who wants to purchase GIS data and orthophotos is required to submit a purchase application to IGN. On the application, the purchaser must agree to comply with the copyright and usage conditions specified therein for the geospatial information. Furthermore, a purchaser who wants to use the geospatial information for secondary usage must submit an application for such usage. IGN will then issue a secondary-usage license to the purchaser. No application needs to be submitted for other geospatial information than the GIS data and orthophotos.

(6) Promotion of Utilization of Paper-based Topographic Maps

Most of the Guinean government agencies including JCC member organizations do not use geospatial information in their daily operations. In the local public bodies such as Dubréka and Coyah Prefectures, in particular, it is difficult to use digital data because only a few computers have been introduced and the electrical power conditions are poor.

Under such circumstances, the meeting members discussed the utilization of topographic maps and made the proposals listed in Table 4-10.


Final Report

103

Table 4-10 Proposals on Utilization of Paper-based Topographic Maps

Purpose of utilization Utilization method

Population management

The geospatial information is required for a national census. The population of each block can be estimated based on the number of houses that can be counted on the maps. If investigators who work in the field carry the maps, omissions can be avoided in the investigation.

Wastes

Illegal disposal of waste is posing a problem. Garbage collection is not sufficiently conducted, either. We can mark the points where illegal disposal is found on the maps and focus on cleaning the problematic areas. Furthermore, geospatial information is useful in enforcing regulation on illegal disposal, planning the placement of trash bins (containers), selecting the garbage collecting routes for garbage trucks, etc.

Security Demonstrators march frequently near the Conakry Airport. We can mark on the maps the areas where marches occur and locations of crimes to select priority security areas.

Tax collection The display of houses on the maps may be utilized for tax collection. Alternatively, it may be utilized for collection of public utility charges.

Illegal road occupation

It is often observed that the external walls of buildings are built in a way to occupy roads illegally. At present, such walls are marked with color sprays. If illegal walls are marked on the maps, awareness activities for planned removal of them can be carried out.

Master plans

The geospatial information can be utilized to plan infrastructures and make master plans for land development and water services, etc. However, there is not yet geospatial information for the entire Coyah and Dubréka areas so that new geospatial information must be created depending on the areas to be developed.

Residence indication

Except in the central area of Conakry City, there is no address in Guinea. The geospatial information can be used to determine addresses and plan the placement of residence indication plates. We can mark the locations of existing residence indication plates on the maps, which can then be used as registers for management.


Final Report

104

Purpose of utilization Utilization method

Measures for mitigating traffic

congestion

There is chronic traffic congestion toward the Kaloum area (business and government office area in the peninsula) in the morning and in a reverse direction to the above in the evening. We can mark the congestion areas on the maps to identify the status quo of congestion and utilize the maps to examine the measures to alleviate the congestion. For the shifting of the central lane (change of the number of lanes depending on the time zone) in the rush hours in the morning and evening, too, we can mark the status quo on the maps to examine the countermeasures.

Requests to JICA (Project Team)

The JCC members made the following requests to the JICA Project Team, which promised to report them to the JICA headquarters. The Project Team was requested to: Provide the GIS technical training provided to IGN also to the JCC members. In

particular, they want training on how to handle and use digital geospatial information because they have little experience in using it (Consensus of all the JCC members).

Examine the introduction of computers and hard disks because such equipment is needed to use digital geospatial information (Request from Conakry City and Coyah and Dubréka Prefectures).

Distribute the 1/5,000 Topographic Map Booklet (Full Size) not only to IGN, Conakry City, and Coyah and Dubréka Prefectures but also to other JCC members (Request from MATD and MUHC).

Create new topographic maps for the entire land of Guinea for the sake of national land development and progress of Guinea, considering that more than 60 years have passed since the creation of the existing national map of Guinea (Request from IGN).

Consider creating geospatial information for the areas out of the mapping range in this Project because Conakry City is expanding (Request from MP and MUHC).

As disorderly land usage is expanding not only in Conakry City but also in provincial cities, geospatial information must also be created for them (Request from MATD).

JICA has been contributing to the geospatial information development of Guinea. They hope that JICA will continue to provide technical assistance to Guinea (Request from IGN).

4.4 Smooth Supply of Geospatial Information

The following materials were prepared to allow the C/P to provide the geospatial information smoothly.

Guide to Acquisition of Geospatial Information

The Project Team prepared a guide that summarizes the acquisition information for the geospatial information to be supplied, such as the types, prices, index map, place and time of reception, and procedure from reception to supply. This guide is provided at the end of this Report.

Figure 4-9 Guide to Acquisition of Geospatial Information (Part)

Durable index map A person who wants to purchase GIS data or orthophotos needs to find a desired map number

in the index map. Since the index map will be used extremely frequently, the Project Team prepared a durable and water-resistant index map printed on a vinyl cloth (one meter in height by 1.5 meters in length) to prevent deterioration of it. This map can be folded and carried and repeatedly marked with a marker and erased and is useful during discussions.

4.5 Proposals on Utilization

The Study Team will submit to the C/P and its supervising authorities the proposals listed below for the establishment of the “National Geographic Information Database Available to a Variety of Institutions” based on the problems identified through discussion in the JCC meetings.

Proposals on Supply of Geospatial Information Proposal 1 - Construction and simplification of a system for supplying

geospatial information Proposal 2 - Ensuring of transparent sales and inventory control Proposal 3 - Security measures

Proposals on Utilization Proposal 4 - Fostering of technical advisors for promoting geospatial

information Proposal 5 - Active public relations Proposal 6 - Transition to digital maps


Final Report

118

(1) Proposals on Supply of Geospatial Information

Proposal 1 - Construction and simplification of a system for supplying geospatial information IGN does not have a section for customer relations nor a main telephone number or main

e-mail address. At present, the mobile telephone number and e-mail address of the Director-General of IGN are used as the contact points for inquiries on the geospatial information. If the Director-General is absent on a business trip or on vacation, however, the customer will not be able to contact IGN. At the earliest possible date, IGN must have a main telephone number and a main e-mail address in order to construct a system in which an inquiry can also be answered by the secretary or Deputy Director-General.

For supply of geospatial information, IGN should avoid supplying paper-based maps as much as possible because expensive consumables such as printers and plotters will be required. Instead, it should supply maps in electronic media (DVD) to simplify the workflow and reduce the costs. We recommend simplifying the selling procedure using a prescribed purchase application or secondary usage license to ensure quick response to customers.

Proposal 2 - Ensuring of transparent sales and inventory control

IGN says that the income earned by selling the geospatial information will be used for maintenance and management. The Project Team proposes that IGN, when selling the geospatial information, should be sure to issue a receipt, enter the sale in the sale management sheet, and record the inventory status in order to enable sharing of the sales and inventory status among the IGN officers.

Proposal 3 - Security measures

Since the current IGN office does not have any lock at the entrance, anyone can go directly to the doorway of any room. All the rooms are locked but no security guard is assigned. Although the electricity supply is gradually becoming more constant, the electric power is down in many of the hours. Since none of the rooms is dust-proof or moisture-proof, they constitute an inappropriate environment for storing computers and hard disks that are susceptible to dust, high temperatures, and humidities. However, this situation cannot be easily improved because of insufficient budgets. The following methods are proposed to store data appropriately even under such circumstances.

(1) Storage of the original data in a lockable cabinet Store the original data (GIS data) in a locked cabinet or safe at all times. Install the cabinet in a well-ventilated place away from direct sunlight.

(2) Creating backup data from original data Create backup data on a reliable storage medium. Store the original data in a cabinet and use the backup data for daily operations.

(3) Periodical virus scan Periodically scan the computer with anti-virus software to prevent infection by viruses.


Final Report

119

(4) Periodical checkup of hard disks Periodically check the hard disks with diagnosis software to prevent corruption of data.

(2) Proposals on Utilization

Proposal 4 - Fostering of technical advisors for promoting geospatial information In Guinea, digital geospatial information is utilized only by a limited number of government

agencies. IGN must carry out positive promotional activities toward various agencies so that many agencies utilize the geospatial information in their daily operations and projects to make improvements and enhance the efficiency of business activities. Additionally, the Project Team proposes that engineers who can be instructors should be fostered in IGN so that inquiries and consultations from users can be answered.

The instructors must acquire not only GIS-related skills but also instruction skills with which they can plan training programs and stimulate interest of participants in consideration of their circumstances as well as bidirectional communication skills with which they can encourage the participants to receive training spontaneously. If IGN has difficulty in fostering instructors in-house, it should also consider requesting the international organizations and donors for technology transfer for fostering instructors.

Proposal 5 - Active public relations

IGN and the Ministry of Public Works and Transport, the upper organization of IGN, do not have a media that can be utilized in public relations such as a website or newsletter. The Project Team proposes that IGN should extensively advertise the activities of IGN and use of the geospatial information by positively participating in the events (exhibitions and seminars) hosted by government agencies and international organizations to exhibit topographic maps and conduct free distribution and sale of the Topographic Map PDF and the Simple Map of Conakry City. IGN can minimize the costs by participating in events hosted by public agencies. Furthermore, it can utilize the index map (printed on vinyl cloth with rings for wall hooks) provided by the Project Team.

Proposal 6 - Transition to digital maps

The Project Team proposes that IGN should not only carry out Proposal 5 but also open its own website to construct a system for distributing digital geospatial information. The availability of Topographic Map PDF for browsing and downloading will promote utilization of geospatial information.

Furthermore, IGN should scan and archive the past materials of geospatial information such as the existing topographic maps (scale: 1/50,000), organize the owned information and supply it directly or via the website.
