| Abstract: | The MapSuv System has extensive applications in GIS-based city construction. By virtue of the SUV data, 2D-map coordinates and virtual realistic technology, the SUV production expressions transform 2D into 3D by directly building a 3D virtual map based on metrical data such as spatial features and attribute information. This paper discusses the structure, data organization and system function of the SUV 3D simulation system, and introduces the data source, data disposal, foundation of model database and texture database, display and output of 3D visual map. This system integrates many technologies such as GIS, VRML, and mapping, which provide the function of data modeling, scene cruise, attribute inquiry and the provision of a 3D impression of a 2D map. This system has a short modeling cycle and the lower workload, which can be used in many fields such as city, planing, mapping, traffic etc. |
