DEM-H:澳大利亚 SRTM 水文强制数字海拔模型
基于水文的数字海拔模型 (DEM-H) 派生自 NASA 在 2000 年 2 月获取的 SRTM 数据。该模型已进行水文条件化处理,并强制执行排水。DEM-H 基于 SRTM 海拔和已映射的河流线捕获流路径,并支持描绘… 澳大利亚 dem elevation elevation-topography ga geophysical -
DEM-S:澳大利亚平滑数字海拔模型
平滑数字海拔模型 (DEM-S) 派生自 NASA 在 2000 年 2 月获取的 SRTM 数据。DEM-S 表示地面表面地形(不包括植被地图项),并且已经过平滑处理以减少噪声并改进表面形状的表示。自适应流程会更 … 澳大利亚 dem elevation elevation-topography ga geophysical
