• output/maps: Maps of geographical regions at an individual level, as well as with subregions in geojson format.
• output/compressed_maps: Compressed version of output/maps. Smaller in size, optimized for web loading, and to be used only for visual representation. DO NOT USE THIS FOR ANALYSIS.
• output/maps/warnings.txt: Since Map Data and Hierarchy Data were obtained from different source, there are some mismatches. Some regions have maps but are not in LGD, and vice-versa. Those regions are listed here.
