Database

CETRAD maintains a comprehensive database of geospatial data for Kenya and for target areas of the NCCR North-South and ESAPP Programmes in Tanzania. This database contains thematically structured datasets at regional, national and International levels; and also contains spatial datasets in ArcInfo coverage and geodatabase data formats. The regional database holds datasets for Laikipia, Mwingi, Makueni, Baringo and Kajiado with varying densities of coverage. More districts will continue to be covered with time.

Currently, the database contains themes such as:

• Infrastructure and social services (road network, railways, health facilities, educational facilities, etc);
• Administration and politics (Administrative boundaries to sub-location level, constituency and wards boundaries, etc);
• Ecology (forests, lakes, rivers, land-cover, land use, wetlands, conservation areas);
• Socio-economic and human settlement data (population density and distribution, land-ownership, land use, property boundaries, towns and trading centres, etc);
• Topography: (Contours, DTM and Topographic maps [1:50'000, 1:100000, 1:250000] and satellite images), among many more

The Database has over 95% coverage of completely geo-referenced topographic maps at 1:100,000 and over 65% coverage of geo-referenced 1:50,000 topographic maps.
