BASIS AND OBJECTIVE OF CO-OPERATION

• co-operation agreement of 28.11.2002 between the Estonian National Land Board and Statistics Estonia– administration and publishing of spatial data

– presenting the relevant statistical data on maps over the Internet

• significant is that in presenting mapped statistical information in an interactive form over the Internet, Statistics Estonia may use the relevant system developed by another state agency, the Land Board


• In the framework of co-operation contract (non-monetary) in joint management (administering) of spatial data Statistics Estonia has an opportunity

– to use web map server of Land Board

– to create interactive map applications on the web map server

• While creating map applications the following maps are used as background maps

– Map of administrative and settlement divison (borders) of Estonia

– Estonian Base Map 1:50 000

– Estonian Basic Map 1:10 000

– orthophotos (black-and-white and coloured) 1:10 000, 1:2 000

THE AIM OF TESTING

• To analyse by comparison of geographical location and address which buildings (objects) in the other data sources are located on CM

• On basis of which data sources it is possible to complement the CM (to add objects (buildings) from BM, from SP (enterprises and social organisations)

• Comparison of geographical location of buildings based on co-ordinates and using the 10m buffer as well as the comparison based on the exact addresses of buildings using also the type of building, the name of owner, the code of cadastral unit, the numer of dossier of BR

• Cooperation with LM - the dissemination of CM to LM (cities and rural municipalities) on the basis of temporary licence agreement


Why are we making this test ?

Two reasons:

• To provide for Censuses an updated and complete digital map on the building level (for planning, for field works, for output)

• For the current statistics, to link the statistical objects with the map for location-based analysis of statistical indicators (incl. point-based analysis)

Thus:

• The need to improve and update digital CM using digital information from other data sources without conducting expensive field works

• The developed BR will be linked to BM, all objects in BR will be linked to the polygon of building on the BM and the respective co-ordinates will also be saved in BR, consequently, CM can be improved on the basis of BR

• The updating of BM by the Land Board will be carried out every five years

• The updating of information on roads by the National Road Administration - road register is updated every year only for state roads based on Base Map (1 : 50 000) with graphical interface but for local roads there is no register and no graphical interface at the moment


Comparable data sources of Census Maps and of other institutions

Data sources in Statistics Estonia

1. IT Department GIS section

Basis : Census Map of the 2000 Population and Housing Census (buildings are connected with the list of inhabitants)

In urban areas – co-ordinates of centroids of buildings and exact addresses for residential buildings (name of settlement, name of street, number of house); field works – 1999

In rural areas – centroids of residental buildings in the farm and unique reference numbers of farms within the village and in addition (name of farm, name of owner); field works 1998 – 1999

Updating :• Version improved by enumerators - 1st quarter of 2000• Version of updated centroids – 4th quarter of 2002 Urban areas by Regio Ltd Rural areas by Estonian Mapping Centre Ltd


2. Enterprise Statistics Division

Statistical profile

• Economic units (EcU) :

Addresses - data received in 1st q 2003

in urban areas – exact address;

in rural areas – address on the settlement level

Name and economic activity of economic unit - data received in 3rd q 2003

3. Population and Social Statistics Division

Data received from (this information has not yet been analysed) :

• Ministry of Education – the list of schools with addresses - 3rd q 2003

• Ministry of Social Affairs – the lists of social welfare institutions, shelters, children’s homes and hospitals with addresses - 3rd q 2003 (data about 2002)


Comparable data sources of other institutions

• Ministry of the Environment

Land Board - Basic Map (BM) of Estonia (1:10 000)

- polygon (co-ordinates) of building and address (in towns – exact address; in rural areas – address on the settlement level, in some cases with the name of farm) Field works 1995-1996; data received in 2nd q 2003

• Ministry of Economic Affairs and Communications

Building Register (BR) – addresses of buildings (partly with numbers of farms) and type of building and name of owner; data received in 1st q 2003

Supporting systems and legal acts (as at 2003 2nd q)• State Dwelling and Building Register and the Register of Constructions are transformed in to the one register and renamed as Building Register starting from 01.01.2004• The draft of the regulation on the System of Address Data will enter into force on 01.01.2004 and the address databases should conform to the regulation by 01.07.2004 • The draft of the System of State Databases Act will enter into force on 01.01.2004• The new version of the Personal Data Protection Act will enter into force on 01.10.2003


Problems - Which types of buildings are preserved and updated on CM ?

• Information from different data sources originates from different time periods (CM and BM, SP, ministries) • In rural areas the exact address of building is missing, usually the address is available only on the settlement level (BR, BM, SP)• Information is not complete (BR, BM)• Different data sources use different classifications (CM, BM, BR) for the differentiation of residential, social and outbuildings • For rural areas, perhaps it is necessary to change the background map (Estonian Base Map 1:50 000) of CM into the new background map (Estonian Basic Map 1:10 000)• The making of town maps and their updating is not regulated by Land Board• The use of CM by the LM is problematic due to shortage of software and qualified staff, the map scale is not good for multipurpose use, the map information is not updated, not linked to registers, the address standard is missing• The formation of Census Address File (CAF): to specify the new structure, to estimate the quality of the existing CAF, the high precision of geo-coding for co-ordinate address, to find co-operation partners, to work out the methodology of updating, timetable, info-technological environment taking into account the international experiences


Results of comparison

• CM&BM: If the geographical location of building is the same then we can add the address from BM to the CM DB• CM&BR: If the building is on the CM then we can add the type of building to CM DB. In the future when the BR includes the co-ordinates of buildings we can add the new buildings into the CM • CM&SP: If the building is on CM we can add the additional information about enterprises into CM • CM&LM: About 1/3 of LM is using the CM and about 20% have made proposals for the updating of CM such as :

- to link CM to cadastral map (1:10 000); to update information on roads and other background information; to improve and update information in BR; to co-operate with LM in the updating of CM based on regular checking of information or regular provision of information on LM; to establish regular updating procedure via BR based on common web-based interface for all municipalities, some towns have also proposed to update the maps themselves


Comparison of CM with Estonian Basic Map (BM)

Comparison of geographical location of buildings:

Which buildings shown on BM are on CM ?

Number of buildings : CM – 27 555

Number of buildings : BM – 47 907

Of which : 13 576 - centroid of CM is inside the polygon of building on BM

34 331 - centroid of CM is not inside the polygon of building on BM

Of which: 5 603 - building on BM is inside of the 10 m buffer of the

centroid of building on CM

28 728 – building on BM is outside of polygon and buffer of

building on CM

• Which buildings shown on BM are on CM ? Comparison by type of building• Which centroids of buildings on CM are on BM ? Comparison by type of building• Centroids of CM and building on BM coincideComparison of addresses• Comparison of CM with Building Register (BR)• Which buildings from BR are on the CM Comparison of addresses• Which buildings on CM are in BR ?Comparison of addresses• Comparison of CM with Statistical Profile (SP)• Objects of Statistical Profile and buildings on CM Comparison of addresses


• Use Estonian Topographic Database (ETDB) from Estonian National Land Board (ENLB) for updating Census Maps • Use of Building Register (BR) from Ministry of Economic Affairs and Communications (MEAC) for updating maps and attribute data • Use of Population Register (PR) from Ministry of Internal Affairs (MIA) for updating data of inhabitants• Use co-operation with local governments and private companies for updating maps and attribute data• Testing the linkage of maps and registers in urban and rural areas

THE FUTURE DEVELOPMENTS OF CENSUS MAPS – CO-OPERATION in 2006


NEW TESTING PHASE - 2006TESTING AREAS:

• HARJU county– VIIMSI and RAE rural municipalities

• JÕGEVA county– JÕGEVA city– TORMA rural municipality– KASEPÄÄ rural municipality

DATA SOURCES:– DIGITAL CENSUS MAPS 2000 (SE)– ESTONIAN TOPOGRAPHIC DATABASE 2006 (ENLB)– BUILDING REGISTER 2006 (MEAC)

TESTING PERIOD: June – November 2006RESULTS: December 2006


PROBLEMS IN TESTING IN 2006The aim of testing:• matching the residential buildings from Census maps with residential buildings on ETDB (only 80% of real estates are included)Problems in urban areas:• in the ETDB there are not addresses for all buildingsProblems in rural areas:• different scales (CM – 1:50 000; ETDB – 1: 10 000)• CM has only centroids of farms not shapes of buildings and due to the different scale there will be the shift in the co-ordinatesLinkage with BR:• there is ongoing process of linking buildings from BR to buildings in ETDB (without this link is not possible to link buildings from Census maps)
