Accuracy Analysis of DEM Generated from SPOT-5 Satellite Imagery
SPOT-5 위성영상으로부터 DEM 생성 및 정확도 분석
Abstract
This paper presents photogrammetric processing to generate digital elevation models and deals with the accuracy potential of SPOT-5 HRG supermode imagery for DEM generation. The DEMs obtained from digital topographic maps of 1/5000 scale were used as the refernce DEM data. DEMs extracted from HRG dats were compared with digital topograpic map DEMs on severed test sections. And digital surface model(DSM), refering to above the ground like buildings, was produced about the test built-up area.
