摘要
从2 m规则格网数字表面模型的数学精度方面,分析了房屋边缘格网误差产生的原因,对检测点落入格网的高程误差分布进行了统计,提出了在数字表面模型房屋区域检验中加入平面精度,为今后的数字表面模型(DSM)质检提供借鉴.
Abstract
This article analyzes the mathematical accuracy of the 2-meter regular grid digital surface model and the reasons for the gen-eration of grid errors at the edges of buildings. The distribution of elevation errors of inspection points falling into the grid is statistical-ly analyzed,and it is proposed to add planimetric accuracy to the inspection of building areas in the digital surface model. This pro-vides reference for future quality inspection of digital surface models (DSM).
