This vector layer (polygon) – reference scale 1/200 000 – is an aggregated sub-basin delineation of the CORB-Contributing area,incorporating basins of the main tributaries only. It was created by aggregation of the sub basin units from the Sub Basins Level III. 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.

Delineation of aquifer systems in Angola, that share geographical overlapping with the Okavango Basin. Source: Generated for the EPSMO project based on hydrogeological map of Angola provided by Direccao de Geologia e Minas at 1/1000000.

This raster layer (90m resolution) represents streams in the CORB-Contributing area. This layer was created by interpolating the Flow Accumulation raster. All cells in the input Flow Accumulation grid that have values greater than a defined threshold have a value of “1” for Stream Definition. 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 infered sub-surface 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 filtering the Drainage Network model with the Surface Drainage Network model. 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 layer represents the political administration level 2 boundaries (level of Commune, and Constituency) in Angola and Namibia, that share geographical overlapping with the Okavango Basin.

This raster layer (90m resolution) represents the flow accumulation in the CORB-Contributing area. This raster was created by interpolating the Flow Direction raster grid to discern the accumulated number of cells with flow direction upstream of a cell, for each cell in the input grid.
