This raster layer (90m resolution) identifies stream segments in the CORB-Contributing area. Each segment has a specific grid code, which will be fundamental in later modelling of the hydrological network. Source: This layer was created by computations of the Flow Direction and Stream Segmentation raster grids. 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 vector layer (polygon) - reference scale 1/200 000 - also identifies the catchment area for each stream segment in the CORB-Contributing area. The value for each polygon corresponds to the value carried by the stream segment that drains that area, defined in the Stream Segmentation grid. Source: This layer was created by converting the Catchment Grid raster layer into vector format. 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 vector layer (line) – reference scale 1/200 000 – is a drainage network model of the CORB-Contributing area. In the attributes table, each drainage line is linked to the micro catchment in which it resides. The creation of this layer was achieved by converting the Steam Segmentation grid layer into vector layer. This dataset is part of the GIS Database for the Environment Protection and Sustainable Management of the Okavango River Basin project (EPSMO).

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. This dataset is part of the GIS Database for the Environment Protection and Sustainable Management of the Okavango River Basin project (EPSMO).
