| Abstract: | In this paper, the origin and applications of 3DGIS are briefly reviewed. And then the authors discussed the key technologies of 3DGIS in detail, such as 3D spatial data acquisition in which several main functions were compared, 3D data model depended on WU Li-xin''s theory, the applications referred 3D spatial analysis, 3D visualization, and so on. At last, the authors indicated the difficulties of realizing 3DGIS and the significance of developing 2.5DGIS based on the argumentations above. |
