摘要:
 随着硬件设备、信息技术和媒体技术的迅速发展，大规模虚拟地形场景得到了越来越多的关注，三维数字城市的重要性也越来越突出，同时出现了一些技术难点。针对三维数字城市建设中三维可视化表达模型和可视化技术的难点问题，提出了一种基于MapGIS技术的三维数字城市技术，采用了MapGIS技术和Sketchup平台相结合，通过制作精细的二维地图数据、三维模型并通过二维地图数据与三维模型的无缝结合，实现了三维数字城市。具体的实例结果表明，在三维建模、三维模型存储和三维模型可视化的整个过程中体现出快捷、交互性好、浏览效率高等优点，较好地解决了技术的难点。为三维数字城市建设提供了一种新的方法，为三维数字城市的实现提供了技术参考。
Abstract:
 With the rapid development of hardware equipment,information and media technology,the virtual terrain scene with large scale has become more and more concerned by people,and some technical difficulties have emerged. In order to solve the difficulties in the process of 3D digital city construction,such as the technique of 3D visualization expression model and visualization,a 3D digital city technology based on MapGIS is proposed. The combination of MapGIS and Sketchup platform,the three-dimensional digital city is real-ized through the production of fine two-dimensional map data,three-dimensional model and seamless integration between two-dimen-sional map data and three-dimensional model. The specific example demonstrates that the whole process of 3D modeling,3D model stor-age and visualization of 3D model is fast and interactive,with high efficiency,which solves the technical difficulties well. It provides a new method and technical reference for the construction of 3D digital city.
