Hallakort / Slope map

Slope map of Iceland (in Degrees and Percent units).

The slope gradient (slope, slope steepness) identifies the steepest downhill slope for a location in a surface: “the inclination of the land surface with respect to the horizontal plane”

Basic local land-surface parameters. First partial derivative from surface.

Statement

The slope gradient was estimated by Whitebox geotool that uses Horn’s (1981) 3rd-order finite difference method (Gallant and Wilson, 2000).
