ProGreen Suitability Analysis
In support of the World Bank's ProGreen program, the GOST team are developing rudimentary tools and processes for generating site suitability maps based on open geospatial layers. The goal is to provide rough guides to task teams for future investigations for suitable project locations.
The process involves identification of ~10 foundational geospatial layers, and determining each layer's contribution to identifying suitable sites. This requires applying weights to values in each dataset, according to the specific investigation of interest. In the first example, we will be looking into questions of reforestation, but this methodology could be applied to other land projects such as ...
