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.

Visitors to the GADM website can download administrative boundaries for individual counties or they can download admin boundaries for the entire world. The Geospatial Centre only has available from it's server the administration boundaries for the entire world.

In May 2014, the Geospatial Centre acquired GADM data (Version 2.0 (January 2012).
