DEM-H: オーストラリア SRTM 水理的に適用されたデジタル標高モデル
水理的に適用されたデジタル標高モデル(DEM-H)は、2000 年 2 月に NASA が取得した SRTM データから派生したものです。モデルは水理的に条件付けられ、排水が適用されています。DEM-H は、SRTM の標高とマッピングされたストリームラインに基づいて流路をキャプチャし、次のような境界線の描画に対応しています。 オーストラリア dem elevation elevation-topography ga geophysical -
DEM-S: オーストラリアの滑らか化されたデジタル標高モデル
スムーズ化デジタル標高モデル(DEM-S)は、2000 年 2 月に NASA が取得した SRTM データから派生したものです。DEM-S は地表地形(植生対象物は除く)を表し、ノイズを低減して地表形状の表現を改善するためにスムージングされています。適応型プロセスにより、より多くの オーストラリア dem elevation elevation-topography ga geophysical -
