摘　　要：简单探讨了航天远景平台下利用ADS100影像进行DEM编辑、DOM制作、DLG生产的方法和特点。空三加密后的ADS100影像数据,需做处理后在航天远景平台下才能使用,然后通过创建工程、加载影像、合成像对,完成前期准备,多次实践后总结出的DEM编辑方法,可以提高精度和效率,DEM接边合并后微分纠正DOM,可减少镶嵌难度。DLG生产中采用前后视,可提高高程精度。We introduce the method s a nd fea tures of edi t ing DEM an d g ene ra t ing DOM an d DLG by us ing ADS100 bas e d on MapMatrix. After aerial triangulation, ADS 100 data should be processed before being used in MapMatrix. Through producing block, loading image, synthetic stereo image, we completed the preparation and summarized the methods of editing DEM after practice. The methods of DEM editing can improve the accuracy and efficiency. Production of DOM uses merging DEM and dif-ferential rectification, which can make mosaicking image easier. The use of forward view and backward view in production of DLG can improve accuracy of elevation.
