BD Carthage Métropole - 2017

The BD CarTHAgE ® (Database on Thematic Cartography of the Water Agencies and the Ministry in charge of the Environment) is the result of the national desire to have a system of spatial tracking of surface aquatic environments for France. It is produced by the Water Agencies from the IGN's BD CARTO ® cartographic database, which describes in digital form all the information present on the national territory. It is updated annually in a cycle involving water agencies and IGN.

The CarTHAgE® comic is free of charge to any third party for non-commercial use.
