Abstract
Using the state 1:50000 DEM and 1:250000 DEM as referenced contrastive data, taking Shaanxi province, which has many different types of relief, as test sample, this paper analyzed the differences among SRTM DEM, 1: 50000 DEM and 1: 250000 DEM data for visibility analysis, and studied the applicability of SRTM DEM in visibility analysis. The results showed that the accuracy of visibility analysis based on SRTM DEM was higher than that based on 1: 250000 DEM data. The visibility analysis based on SRTM DEM had better accuracy in plain areas, but had worse accuracy in mountainous areas.关键词
