| 摘 要： | Reference 3D是法国Spot立体卫星影像生成的DEM、ASTER DEM是高分辨率卫星成像设备—ASTER获取的立体影像生成的DEM,它们全球覆盖范围广、数据获取快、质量稳定。针对我国缺乏1:10000或1:5000基础地形资料的地区、难以获取资料的海外交通建设地区,本文探讨基于这两种DEM进行公路勘察设计。工程实践表明:Reference 3D相比ASTERDEM有着更高的精度,质量更加稳定可靠,可以满足公路勘察设计中规划、工可等阶段的需要,从而提高工作效率,缩短外业周期,降低成本。

| Abstract: | Reference 3D is a DEM which made from the image take by Spot.And ASTER DEM is produce by a stereo image pairs take by ASTER--a high-resolution satellite.They cover most of the global,and can rapid acquire data,and their quality are stable.Based on these two kinds of DEM,this paper will discuss highway survey and design in the area where lack basis terrain data in our country and the area where difficult to get those data.The results showed that Reference 3D compared to Aster DEM has a higher precision,it ca... |
