Research and Realization of Urban 3D GIS Based on ArcGlobe

In order to the meet the needs of digital city,to construct a powerful urban 3D GIS is extremely urgent.According to the aerial images,CAD topographic map,as well as the collected parameter and texture data of buildings,an urban 3D model was constructed by the combined model of ArcGlobe 10.0 and 3ds Max,which realized the 3D GIS functions of constructing and managing 3D data,altitude measurement and sight line analysis.
