MAIN OBJECTIVES
Provide the local partner with a GIS
product that …
… is able to provide a precise measurement of
interesting targets
… is easy to use and update regularly
… is fully developed with OS technology to ensure
future sustainability
… can be replicated in other main similar
neighboring environments
… can be highly customized and
eventually translated in local languages
… can be linked with existing data/procedures

GIS / GPS TRAINING
On site training in Somaliland
Remote training in Kenya

FIELD TRAINING
![Page 8: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/8.jpg)
GIS FIELD DATA COLLECTION
Easy-to-fill field forms for information data collection
![Page 9: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/9.jpg)
FIELD DATA COLLECTION
Getting information of sample vegetation plots in the Wire Hill Forest
High precision geometric data collection with differential GPS of Gabiley buildings
![Page 10: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/10.jpg)
The implemented extensions (WIRE FOREST and SOMALILAND) support users during the whole workflow from the loading of field collected points, data entry, labelling and
merge procedures in order to have only one final vector layer
GPS collected points (3D)
GPS collected points (2D)
Note that all the implemented tools can beaccessed by dedicated menu or by toolbar.
DATA MANAGEMENT WORKFLOW
GPS collected points (2D)
Derive Polygons

The merge tool allows the user to easily merge collected data among them by mantaininga predefined attribute table schema and make easier the data entry procedure

• NavTableForms is a “library to build navigable and validatedJava forms for gvSIG, ala Navtable”.
• It allows the implementation of user-friendly custom formsbased on NavTable but with further functionalities, such asvalidation rules and domain values.
ABOUT NAVTABLE FORMS
HOW TO USE NAVTABLEFORMS?
1. Definition of the data model2. Definition of the field form3. Design of the ‘sketch’ form with Pencil4. Design of the form with Abeille Forms Designer5. Implementation of the gvSIG extension
![Page 13: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/13.jpg)
An open-source GUI prototyping tool that's available for ALL platforms.
DESIGN OF THE ‘SKETCH’ FORM WITH PENCIL
http://pencil.evolus.vn/
This tool is very useful in order to represent graphically and then share
quickly a prototype/sketch of the form.

DESIGN OF THE FORM WITH ABEILLE FORMS DESIGNER
![Page 15: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/15.jpg)
IMPLEMENTATION OF THE GVSIG EXTENSION
![Page 16: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/16.jpg)
THE FORM IN ACTION
![Page 17: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/17.jpg)
Building ID and area are automatically calculated.
Data entry is made easier through dropdown lists or
checkbox
THE FORM IN ACTION
checkbox
Photo file can be selected and an automatic hyperlink is
activated
NavTable standard tools are available also in this tool
![Page 18: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/18.jpg)
The number of editable tree species is automatically limited according to the
entered value in “No. of tree species”
THE FORM IN ACTION
The list of species that can be entered, depends on the “Forest area” selected value
![Page 19: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/19.jpg)
THE FORM IN ACTION
As previously, also the tag “Family 1” and “Family 2”
become editable according to the entered value in “No.
of families”
Total number of persons is automatically calculated for
each family
![Page 20: gvSIG applications in East Africa:Kenya and Somaliland](https://reader034.vdocuments.net/reader034/viewer/2022052619/55507765b4c905cc0f8b516a/html5/thumbnails/20.jpg)
Allowed values in dropdown lists can easily be modified by editing the file “.domain” files with any text editor software
HOW TO MODIFY THE VALUES IN DROPDOWN LISTS

30 field survey days
Almost 800 polygons created (± 20% total)
SURVEY : RESULTS AND CONSTRAINTS
SOMALILAND
(± 20% total)
Few survey duringtraining on the job
Survey teams change
No previous experience on survey
