The Food and Agriculture Organization of the United Nations (FAO) with the collaboration of the International Institute for Applied Systems Analysis (IIASA), has developed a system that enables rational land-use planning on the basis of an inventory of land resources and evaluation of biophysical limitations and potentials. This is referred to as the Agro-ecological Zones (AEZ) methodology.

This raster layer represents the Digital Elevation Model (DEM) of the CORB-Contributing area, in the reference scale of 1/200 000. It was created by converting raw SRTM data into a finalized raster layer for the CORB-Contributing area with 90m pixel resolution. This dataset is part of the GIS Database for the Environment Protection and Sustainable Management of the Okavango River Basin project (EPSMO). Detailed information on the database can be found in the “GIS Database for the EPSMO Project” document produced by Luis Veríssimo (FAO consultant) in July 2009, and here available for download.

This raster layer represents the slope model of the CORB-Contributing area, in the reference scale of 1/200 000. The creation of this layer was achieved by interpolating the DTM raster layer. Units are organized by degrees. This dataset is part of the GIS Database for the Environment Protection and Sustainable Management of the Okavango River Basin project (EPSMO). Detailed information on the database can be found in the “GIS Database for the EPSMO Project” document produced by Luis Veríssimo (FAO consultant) in July 2009, and here available for download.

This raster layer represents the aspect model of the CORB-Contributing area, in the reference scale of 1/200 000. Aspect is the direction that a slope faces. It identifies the steepest downslope direction at a location on a surface. Source: The creation of this layer was achieved by interpolating the DTM raster layer.
