Sub-national level administrative areas

This post documents an interesting source for sub-national level administrative areas, such as city-level shapefiles. This could be particularly useful when you are trying to downscale gridded data to city-level.

The database is GADM (Database of Global Administrative Areas). It provides maps and spatial data for all countries and their sub-divisions. You can browse our maps or download the data to make your own maps.

See an example of spatial data for China. Level-0, 1, 2, 3 stands for county level, province level, city level, and county level I guess. But you should double check that.

See the data package for more information in data format.
