Exchange and superposition of distributed GIS Data via Internet and other services (e.g. LBS), independent of the raised domain-specific data, geographical data, software technologies and data provider The integration of relevant GIS data in the IFC data model has been going to be modelled and developed since October 2003 in Norway (s. IFG). The research group SIG 3D of "Geodaten-Infrastruktur NRW (GDI NRW)" has been working since 2001 on data exchange models for a 3D GIS
