Arguments

DEM

raster - Elevation. Path to a raster layer.

VALLEY

rasterDestination - Valley Depth. Path for new raster layer.

HILL

rasterDestination - Hill Height. Path for new raster layer.

VALLEY_IDX

rasterDestination - Valley Index. Path for new raster layer.

HILL_IDX

rasterDestination - Hill Index. Path for new raster layer.

SLOPE_IDX

rasterDestination - Hillslope Index. Path for new raster layer.

RADIUS_VALLEY

number - Valley Radius. A numeric value.

RADIUS_HILL

number - Hill Radius. A numeric value.

THRESHOLD

number - Elevation Threshold. A numeric value.

METHOD

enum of ("[0] default", "[1] alternative") - Slope Index. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

...

further parameters passed to qgisprocess::qgis_run_algorithm()

.complete_output

logical specifing if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
