数字正射影像图局部更新技术思路探讨

Discussion on Technical Ideas of Local Update of Digital Orthophoto Map

通过分析正射影像生产中对前期项目已有DOM成果利用不足的问题,提出了正射影像局部更新的技术思路,解决了同一区域正射影像成果不能充分利用、重复生产的问题。

This paper analyzed the problem of using the DOM results of previous projects insufficiently in orthophoto production,and put forward the technical idea of local updating of orthophoto,solved the problem that the orthophoto results of the same area cannot be fully utilized and repetitive production.
