大比例尺地形图更新作业方法探讨

Discussion on the Operation Method of Large Scale Topographic Map Updating

本文将从数字测图定义的角度出发,结合实际工程案例,从无人机航空摄影着手,对无人机航摄法成图工序中的像控测量、空中三角测量、XYZ转EPS编码、EPS平台数据标准化编辑及入库加以介绍,进而对大比例尺数字化地形图编辑成图以及建库流程、原则等进行阐述,以便有关部门今后顺利开展类似工程项目提供可靠参考。

this article from the perspective of digital mapping definitions,combined with the actual project cases,from the uav aerial photography,aerial method for unmanned aerial vehicle in the mapping process like turn control surveying,aerial triangulation,XYZ EPS coding,EPS platform data standardization editing and storage were introduced,and then to edit digital terrain map with large scale mapping and database construction process,principles,etc.,so that relevant departments smoothly in the future to provide reliable reference for similar project.
