| 摘 要： | 1 Introduction Geological exploration is one of the most im- portant approaches to study and solve multitudinous geological problems in the development of modern times. Since 1990s, geological work has been con- fronted with a new opportunity that is brought by the rapid development and extensive application of in- formation technology all over the world. It becomes a new working model for studies based on digital spa- tial database, computer cartography and Geographi- cal Information System … |

| Abstract: | Regional Geological Information System combines the multi-dimensional and dynamic spatial information into an integrated spatial information system. 3D geological modeling and its preprocessing or post-processing are the most difficult problems for constructing the system. Based on the current 3D GIS technique, some basic problems in establishing the system are discussed in this paper, including 3D spatial data model, 3D geological modeling, and visu- alization of 3D geological data. A kind of 3D vector data model based on boundary representation for geological object and its topology was developed in order to model and visualize complex geological structures. In addition, some key techniques are pointed out for further study. |
