摘要
以福建农林大学校园为研究对象,借助地理信息系统等软件对遥感影像和地形图进行处理。通过DGPS自由网平差构建校园控制网,在对三维数据处理、地形图矢量化并赋予高程值基础上建立校园DEM,利用ArcGIS软件中ArcScene功能模块构建校园三维虚拟景观模型,进而实现校园景观三维场景的表达和实时浏览。通过三维虚拟景观模型漫游及表达为区域景观布局改进和优化提供参考。
Taking the Fujian Agriculture and Forestry University (FAFU} campus as the research object, the remote sensing image and the topographic diagram were dealt with aid of GIS software. The campus control net was constructed by using DGPS through the free net adjustment. The campus DEM was established through the three dimensional (3D) data processed, the topographic diagram vectored and the elevation value given. The 3D data model was established by using the AreScene functional module of the ArcGIS software. Then the 3D scene expression and the real-time browsing were brought about. The result may provide the reference through 3D virtual landscape model roaming and the expression for the region landscape layout improvement and the optimization.
