摘　　要：本文介绍利用IKONOS的核线投影产品在国产的三种数字摄影测量工作站(DPW)上,按大规模生产的要求,对西藏樟木测区进行1:50000测绘的实践。提出“内业→外业→内业”的作业流程。分析了投影差对DOM的精度影响和DEM与DOM、DLG与DOM数据叠加产生影像位移的问题。Firstly,based on IKONOS epipolar image production,the implementation of 1∶50000 maps at ZhangMu,Tibet is introduced according to the needs of mass production with the help of China's Digital Photogrammetric Workstation(DPW),VirtuoZo、JX-4 and DMS.Then,the working flow of the “Inside job →outside job →Inside job” is proposed.Finally,some problems are discussed in this paper such as the influence to DOM by relief displacement and the image displacement after data overlaying of DEM with DOM as well as DLG with DOM.
