It is significant for water movement across the landscape, i.e., the accumulation or dispersion of water. The plan curvature products were derived from the Smoothed Digital Elevation Model (DEM-S; ANZCW0703014016), which was derived from the 1 second resolution SRTM data acquired by NASA in February 2000. The calculation of plan curvature from DEM-S accounted for the varying spacing between grid points in the geographic projection. The plan curvature data are available at 1 arc-second (approx. 30 m) and 3 arc-second (approx. 90 m) resolutions. The 3 arc-second resolution product was generated from the 1 arc-second plan curvature product and masked by the 3” water and ocean mask datasets. {"type": "Polygon", "coordinates": [[[113.0, -44.0], [154.0, -44.0], [154.0, -10.0], [113.0, -10.0], [113.0, -44.0]]]} 113.0 154.0 -44.0 -10.0 Australia ECOLOGY Landscape LAND Topography Models Land Surface Plan Curvature TERN_Soils http://hdl.handle.net/102.100.100/9239?index=1 documentDigital HTML Unnamed resource documentDigital PNG
