IGN is France's equivalent of the UK's Ordnance Survey. The stated aim of IGN is to produce, maintain and disseminate reference geographic information in France. The latest in a long line of renowned cartographers, IGN has been involved in all cartography-related operations in France and its territories since 1940. IGN have a vast selection including more than 2,000 maps of France, all available in a variety of scales, as well as some excellent maps of other parts of the world. All maps produced by IGN come with an easy-to-use key in English, French and German. More recently, the change in data acquisition techniques and a growing diversified demand, has led IGN to develop a set of efficient 3D mapping technologies.
