| 摘 要： | 结合1：10000 DLG更新的实际，提出了一种基于数字摄影测量工作站的地形图矢量要素更新模式，即充分利用现有的DLG与DEM数据及各要素之间的空间位置关系，将二维表达的矢量要素转换到三维立体空间，进而在数字摄影测量工作站立体环境中进行修侧与新旧数据接边，它既能得到与数字摄影测量立体测图质量一致的成果，且充分利用了现有的DLG成果，达到节约作业成本、缩短作业周期、减少作业工作量的效果。实验表明，本方法具有可行性、可操作性。

| Abstract: | A method for revision of topographic map at 1: 10000 scale based on digital photogrammetry workstation is been introduced in this article. The method which has made the best of the DEM's height information and elements' space dubiety of DLG is transformation the exiting planar vector data to 3D stereo-space and realization revision of topographic map and corresponding the space relationship between old DLG data and new production in a stereo-environment based on digital photogrammetry workstation. Using this method not only we can get product which as same as using stereo mapping,but also we can more reduce the money and time. Experiment shows that the method introduced in this article is feasible and maneuverability and can be widely used. |
