一种基于PhotoMap的1∶10000 DLG地貌修测方法

A Method of 1∶ 10000 DLG Geomorphology Revision and Survey Based on PhotoMap

1∶10 000 DLG数据更新中,地物地貌随着经济和社会的发展变化越来越显著,传统的地貌修测方法比较烦琐,制作周期长。本文介绍一种基于PhotoMap平台地貌修测的方法,在1∶10 000基础测绘快速更新项目生产中开展试验,结果表明该方法操作性简易快速,能显著提高地貌修测的生产效率,且生产精度优于传统方法。

Land features and landforms have become more and more significant with economic and social development in the production of 1∶10000 DLG.In this paper,a method of rapid updating geomorphology revision based on PhotoMap for surveying and mapping is introduced.Production tests are carried out and the test results are analyzed.The results show that this method can significantly improve the production efficiency of geomorphology revision and it’s accuracy is better than traditional methods.
