摘要

摘要: 数字测图系统在城市地理信息系统建设中有着广泛的应用.根据MAPSUV生成的SUV文件数据, 基于二维电子地图的平面位置, 通过虚拟现实技术, 直接将测量得到的地物空间、属性信息直观清晰地显示成三维虚拟地图, 从而实现测图成果的表现方式由二维到三维的转变.对数字测图成果三维模拟系统的设计原则整体结构、数据组织、系统功能做了详细的探讨.介绍了系统数据源、数据处理、模型库和纹理库建立以及三维可视化成果图的显示和输出.该系统集成了GIS、VRML、测绘等理论和技术, 具有数据建模, 场景漫游、属性查询等功能, 再现了二维数字地图的三维景观.测图成果3D模拟系统建模周期短, 工作量小, 可应用于城市规划、测绘、交通等许多领域.

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.
