摘要
DEM作为重要的基础空间数据,在城市规划、建设方面发挥着重要作用。本文利用INPHO数字摄影测量系统,结合高分航空立体像对,探索山地大面积区域DEM数据获取的技术方法,同时对其精度进行了验证评价,为地理国情普查等项目的 DEM生产提供参考。
As an import kind of spatial data, DEM takes a significant role in city planning and construction. In this paper, the technology method of how to capture DEM data in large mountainous area based on the INPHO and high - resolution aero stereo - pairs, and the precision is verified and evaluated at the last part. It is aimed to provide referenced value for the project of national geographic conditions census.
