Abstract: The seamless indoor and outdoor navigation and location-based services for the safety management and emergency response of shopping centers,hospitals,airports,subways and other underground complex interior space are increasingly urgent,this article proposed an indoor location information model which extends the location descriptions of OGC standards City GML and Indoor GML,provides the ontology of relative and absolute indoor locations and lays an important foundation for intelligent location-based services with presenting an automated indoor space extraction of complex 3D building models.
