澳大利亚 5M DEM
从 LiDAR 模型派生的澳大利亚数字地形模型 (DEM) 5 米网格代表国家 5 米(裸地)DEM,该 DEM 是根据 2001 年至 2015 年期间约 236 项单独的 LiDAR 调查派生而来,覆盖面积超过 24.5 万平方公里。… 澳大利亚 dem elevation elevation-topography ga geophysical -
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
