Settlment data surfaces GeoTIFF

The data were developed using computer vision techniques to classify blocks of optical satellite data as settled (containing buildings) or not. Proportional allocation was used to distribute population data from subnational census data to the settlement extents. The data are distributed as GeoTIFF files. The Settlement GeoTIFF represents settlement extents and has a value of 1 where buildings were detected in the imagery. It is possible for buildings to be detected in pixels but no population values assigned in cases where the census data show a unit as uninhabited.
