In 1999, the Carto2001 project was launched by Institut Géographique National (IGN), with IGN selecting 1Spatial’s automated generalisation technology to achieve its target of creating 1:100,000 mapping (Top100) from the BD Carto® database at 1:50,000. Since the BD Carto® database does not hold buildings as elementary objects, the generalisation flowline needed to focus on road networks. The project was initiated on the back of IGN’s leading involvement in the European AGENT project (Automated GEneralisation New Technology).

The IGN Top100 maps are now in full production. IGN is currently using 1Spatial’s technology, including the latest generalization product Clarity, for research and development. The foundations set by 1Spatial are also being used by IGN to develop building generalisation flowlines, to create 1: 25 000 and 1:50 000 mapping from base data at 1:10,000.
