Methodology

The algorithm used to produce this dataset first identifies the clusters of geographic cells with the largest population counts within the region. It then assigns a point to each cluster, and uses these points to generate catchment areas for each of these settlements. The catchment area generation algorithm assigns each block of land to the "closest" settlement. In this context, "closest" refers to the shortest walking time between two points, taking into account land cover, topography, etc.
