Slope measures the inclination of the land surface from the horizontal. Percent slope represents this inclination as the ratio of change in height to distance. The focal median of percent slope can be used as a surrogate for modal slope in landform pattern analysis. The 300 m focal median percent slope 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 focal median slope from percent slope accounted for the varying spacing between grid points in the geographic projection. This collection includes Median of Percent Slope (over 300 m) at 1 arc-second and 3 arc-second resolutions. The 3 arc-second resolution product was generated from the 1 arc-second 300 m focal median of percent slope product and masked by the 3” water and ocean mask datasets.
