The Instituto geográfico nacional (IGN) was set up in 1870. Administratively it answers to the statistics department of the ministry of works, but it is entirely free to work on different technical projects, such as determining the shape and dimensions of ground, mapping topography and the cadastre. Today it is a national benchmark in mapping and observation of territory, and an important cartographic supplier for our collection of maps of Spain.
