GADM is a spatial database of administrative areas, i.e., countries and subdivisions. We provide the GADM data as Linked Data, using the NeoGeo vocabulary. Our data includes links to existing spatial datasets.
Geometries are available in different resolutions (100m, 1km, 10km, 100km). You can access geometries in different formats (KML, GML, GeoJSON...) via HTTP content negotiation.
Example URIs

Data Dumps
You can find data dumps of the RDF in the download section. Please note that we do not provide data dumps of the geometries. You can download the shape files at the GADM project site.
