Narrative Summary

The Institut Geographique National (IGN) was established in June 1940, shortly after the French surrender to Germany. The intention was to replace the previous military mapping service with a civilian organisation which was outside of the remit of the German occupying forces. The IGN survived the war and in 1947 was tasked with making new maps of war damaged France and its colonial territories. To accomplish this huge task, the IGN obtained a number of war surplus B-17 Flying Fortress aircraft from the USAAF to carry out a comprehensive photographic survey of the entire country. IGN maps have been continously updated ever since. In 2012 the IGN was merged with the Inventaire Forestier National to form the Institut National de l’Information Géographique et Forestière (National Institute of Geographic and Forestry Information), but keeping the IGN acronym.

Special Markings

Early IGN aircraft operated in a natural metal colour scheme. This was later refined with addition of a white upper fuselage and a red and white IGN insignia on the nose and fin. More recently, aircraft have adpted an overall white colour scheme with a blue fuselage cheatline and blue/white/red fin markings. The blue IGN logo appears on the fin.
