Arguments

DEM

raster - Elevation. Path to a raster layer.

HEIGHT

rasterDestination - Upslope Height. Path for new raster layer.

SLOPE

rasterDestination - Slope. Path for new raster layer.

ASPECT

rasterDestination - Aspect. Path for new raster layer.

FLOW_METHOD

enum of ("(0) Deterministic 8", "(1) Rho 8", "(2) Braunschweiger Reliefmodell", "(3) Deterministic Infinity", "(4) Multiple Flow Direction", "(5) Multiple Triangular Flow Direction", "(6) Multiple Maximum Downslope Gradient Based Flow Direction") - Flow Distribution. 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 specifying 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.

.quiet

logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.

.messages

logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
