Brief description

Profile curvature is the rate of change of potential gradient down a flow line and represents the changes in flow velocity down a slope. It is significant for flow acceleration, erosion/deposition rates and geomorphology. The profile curvature product was derived from the Smoothed Digital Elevation Model (DEM-S; ANZCW0703014016), which was derived from the 1 arc-second resolution SRTM data acquired by NASA in February 2000. The calculation of profile curvature from DEM-S accounted for the varying spacing between grid points in the geographic projection. This collection includes Profile Curvature data at 1 arc-second and 3 arc-second resolutions. The 3 arc-second resolution product was generated from the 1 arc-second profile curvature product and masked by the 3” water and ocean mask datasets.
