基于ADS80自由网1:2000省级DOM制作方法与精度分析

Process and Accuracy of Large Scale DOM and Mapping Using ADS80 with Free Net

介绍了在湖北省农村土地确权登记发证DOM基础影像制作项目中,采用ASD80数据基于无地面控制点的空中三角测量方法,以及ADS80数据制作大比例尺DOM正射影像的生产方法和关键步骤,对测区范围的空三及DOM进行精度检查和统计分析,总结无地面控制点ADS80数据空中三角测量在大比例尺DOM生产中的高效应用。

In this paper, taking the procedure of the Hubei Ru- ral Land ownership 1 ： 2 0（30 map generating as an example, we give specific details on aero triangulation without control points generating procedure using ADS80 data, discuss about key process. The results are evaluated from the accuracy and efficiency of aero triangulation. And several references are provided for future production in large scale DOM and mapping.
