摘要
以西安市浐灞生态区为例,利用11万地形图在ARCINFO中构建DEM,采用QUICKBIRD影像制作的正射影像作为三维表面的纹理信息.详细叙述了该项目中DEM构建及遥感影像处理的流程方法,包括矢量化、拓扑关系、构建DEM、波段组合、影像增强、几何校正、图像拼接、投影变换、去霾处理以及三维地形景观图的生成.三维地形景观图是一种由基础测绘数字产品相互结合的专题地图产品,并对三维地形景观图的应用前景作了展望.
In this paper ChanHe and BaHe ecosystem is taken as a case, the topographic map at a scale of 1： 10 000 is used to create DEM, and QUICK BIRD image is geometrically corrected as a DOM image that was used as 3D surface texture. Then the flow and the methods in this project are recounted, including vectorization, topology, DEM, bands combination, image strengthening, geometry correcting, image mosaieking, projection conversion, haze reduction and get the 3D landform landscape map. It is a thematic map making from basic mapping digital production, and the author still eaplains the application foregrotmd of the three - dimensional landform landscape map.
