A national mapping agency (NMA) is an organisation, usually publicly owned, that produces topographic maps and geographic information of a country. Some national mapping agencies also deal with cadastral matters.
According to 2007/2/EC European directive, national mapping agencies of European Union countries must have publicly available services for searching, viewing and downloading their spatial data.[1] Maps produced by some of them are available under a free license that allows re-use, such as a Creative Commons license.[2]
