In this paper, we focus our research on spatial data model and visualization techniques on the basis of spatial database in 3D GIS.
We analyze in detail the difficulties in integration of field-based model and object-based model, and propose an object-oriented 3D GIS integrated model. We also discuss the architecture of the integrated model.
Until now, there is no general representation for 3D topological structure, especially topological relationships between 3D solid obje...
