Integrated spatial layers for delineating grazing units in central Borana zone of southern Ethiopia

Database derived by summing up three information layers, namely topographic features, vegetation cover and its dry-out dynamics. Three number codes were adopted to sum up values on a pixel basis and the place value of the number in the code is used to interpret individual pixel behavior. With four categories of topographic ruggedness index, four categories of vegetation greenness index and five categories of vegetation dry-out dynamics, we came up with a thematic layer with 80 classes. In this database, spatial layer is oriented towards topographic features. Resource users can combine these thematic classes to come up with the number of rangelands management units that suits their purposes.
