摘要:At present, thedevelopment and application of outdoor navigation is already quite mature. Carnavigating system and mobile navigating system have been good to meet people’srequirements to find the path in outdoor. With the development of outdoornavigation system, indoor navigation system is also being paid more attention,especially in an unfamiliar and complex indoor environment. This paperconstructs 3D models of the building by SketchUP so as to provide a 3D scenefor indoor navigation system, and builds 3D network model based on the buildingplan by ArcGIS. Finally, a indoor routing prototype system is developed basedon ArcEngine, which does a preliminary study for indoor navigation.
