The FGGD terrain slope map is a global raster datalayer with a resolution of 5 arc-minutes. Each pixel contains a terrain slope class value for the pixel area. The data are from U.S. Geological Survey, 1993, GTOPO 30, as reported in FAO and IIASA, 2000, Global agro-ecological zones, and FAO and IIASA, 2007, Mapping biophysical factors that influence agricultural production and rural vulnerability, by H. von Velthuizen et al.

The FGGD terrain slope constraints map is a global raster datalayer with a resolution of 5 arc-minutes. Each pixel contains a class value for the degree to which terrain slope constrains agricultural production potential in the pixel area. The data are from FAO and IIASA, 2000, Global agro-ecological zones, as reported in FAO and IIASA, 2007, Mapping biophysical factors that influence agricultural production and rural vulnerability, by H. von Velthuizen et al.

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 slope model within the Okavango Basin. Source: Data generated under the GIS EPSMO program (base:OB_DTM). 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.
