基于MapMartix的几种DSM制作方法

Research on Several for Producing DEM Methods Based on MapMartix

基于MapMartix系统对DSM的几种制作方法进行探讨,通过对不同方法所生产的DSM产品进行比较,并对基于DLG方法所生产的DSM产品进行精度评价,得出其精度满足《1∶5001∶10001∶2000地形图航空摄影测量内业规范》要求的结论。

Based on MapMartix system, this paper explores several production methods of DSM, compares DSM products produced by different methods, and evaluates the accuracy of DSM produced by DLG method. The conclusion is that its accuracy meets the requirements of " 1 : 5 00 1: 1 000 1 : 2 000 Topographical Aerial Photogrammetry Industry Standards".
