| Abstract: | 3D GIS will be the next generation of geographic information system(GIS).Ideally,3D GIS should be developed based on good theoretical foundation.Currently,many researches have been carried out both by academic groups and commercial sector to develop 3D GIS application.So far,there is no ideal 3D GIS product available on market partly due to the complicated topology of spatial objects in 3D environment,inappropriate spatial data structures and hardware limitation.Studies carried out indicated that the integr... |
