Global Administrative Areas (GADM)

The Geospatial Centre acquired updated data (version 2.0 - 2012) to "Global Administrative Boundaries" (GADM). GADM is a database of the location of the world's administrative areas (boundaries). Administrative areas in this database include: countries, counties, departments, etc. and cover every country in the world. For each area it provides some attributes, foremost being the name and in some cases variant names.
