GIS and satellite remote sensing are integrated parts of CDE's research and development approach, from basic support with field maps, satellite images and GPS surveys for participatory field-based approaches, to modelling and visualisation of various spatial dynamics, to the development of customised tools for spatial data management.

The geoprocessing unit offers a complete set of customised consulting and implementation services to assist governments, NGOs and private organisations in data acquisition, geographic information management, and capacity building.

Comprehensive GIS and Earth Observation Projects have been realised in East Africa, the Horn of Africa, Southeast Asia, and Central Asia.

The unit consists of a team of geographers and environmental scientists with expertise in GIS, remote sensing, database management and cartography.
