Institut national de l'information géographique et forestière

The Institut national de l'information géographique et forestière (IGN) is a key French public agency established in 1940, responsible for producing and maintaining geographical information across France and its territories. It operates under the Ministry of Equipment and runs four laboratories focused on geographical data research and applications. The IGN manages a variety of products, including topographic and road maps, and is known for its historical role during World War II, where it contributed to the resistance and provided crucial mapping support to Allied forces. Today, it continues to innovate in geographical sciences and offers educational programs through its National School of Geographical Sciences.
