基于SWDC-4的1∶10000基础测绘数据更新

Data update of 1:10000 base map based on SWDC-4

SWDC-4数码航测相机填补了国产数字航测仪相机的空白,与国外UCD、DMC等相机相比具有众多优势,更适用于1∶10 000基础测绘数据更新。本文介绍了SWDC-4在邵阳基础测绘数据更新项目中的作业流程和技术设计过程,统计分析了空三加密和最终DLG产品的精度,为SWDC-4在其他基础测绘数据更新项目中的应用提供了借鉴。

SWDC-4 which supplies a gap for domestic digital air photo instrument,has many advantages over foreign cameras like UCD and DMC,and is fit for data update of base map.This paper intruodced the workflow and process of technical design,statistically analyzed the accuracy of aerial triangulation and final DLG product,provide a typical example for other projects to we SWDC-4 for data udate of base map.
