摘要
从1:2000比例尺数字地面模型(DEM)和1:2000比例尺正射影像(DOM),设计与实施过程入手,系统的阐述了数字地面模型(DEM)和正射影像(DOM)的设计与实施过程和方法。成果的精度经全野外实地全站仪检测比较,符合成图的精度要求,结论认为这项成果能够广泛应用于测绘生产中应用。
This paper starts with the design and implement of 1：2000 DEM and DOM,and expound the process and method of the DEM and DOM＇s design and implement systemically, The resuh＇s precision is compared with the field by Total Station, which meets the precision demand of mapping, so concludes that this production can apply to the production of surveying.
