Research on Mathematical Accuracy of 2m Regular Grid Digital Surface Model
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).
