摘要
主要阐述对地貌特征进行DTM精度<0.15 m的采集和对建筑物顶部各个面通过2D,3D共边处理形成3维模型采集,并在航测生产过程中实施质量控制。
This paper mainly introduces the process that according to the terrain feature,we digitalize the DTM by the accuracy lower than 0.15 meter（0.15m） and deal with the common edges both 2D and 3D of the building roof contours＇ polygons,also during this aerial survey we implement the quality control.
