To complete the two maps we used data collected from the field, including GPS files of points and tracks, two drawings made by community members of their community land, notes, and photographs. Additionally, we used DigitalGlobe’s satellite imagery to digitize relevant land features.
Specifically, the final step can be broken down into the following activities:
- Review of data collected through fieldwork
- Selection and purchase of relevant satellite imagery: DigitalGlobe
- Digitization of natural features identified by the communities
- Design of the two maps using QuantumGIS
These were also the final activities of the training process that we offered to Kenya Land Alliance and Namati on how to collect and manage community land data.
Natural resources and amenities that were either gathered in the field or digitized in post-processing and included on the maps were: rivers, brooks and streams; forests; swamps; ocean; sand dunes; grazing areas; farm lands; village locations; schools; hospitals and dispensaries; mosques and churches; water points; roads; air strip; hotels; bridges; and cattle dips.
Finally, maps that resemble Topo Sheets in Kenya were designed. We chose this style because it offers a sense of familiarity to the citizens and government agencies to whom they will be presented.
To simply indicate the amount of data gathered by our field teams, we compared it to openly available OpenStreetMap data in the area.
Number of points in OSM: 6
Number of points collected during fieldwork: 126
Length of rivers in OSM: 91 km
Length of rivers digitized: 381 km
Length of roads in OSM: 103 km
Length of roads digitized: 110 km
Areas in OSM: 17 km2
Areas digitized: 590 km2
Images below compare what was first input into the mapping process – community’s drawings of their land – and what was the final output of the process – final georeferenced maps.
