Arguments

DEST_TYPE

enum of ("(0) Point", "(1) Grid") - Input Type of Destinations. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

DEST_POINTS

source - Destinations. Path to a vector layer.

DEST_GRID

raster - Destinations. Path to a raster layer.

COST

raster - Local Cost. Path to a raster layer.

DIR_MAXCOST

raster - Direction of Maximum Cost. Path to a raster layer.

DIR_UNIT

enum of ("(0) radians", "(1) degree") - Units of Direction. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

DIR_K

number - K Factor. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

ACCUMULATED

rasterDestination - Accumulated Cost. Path for new raster layer.

ALLOCATION

rasterDestination - Allocation. Path for new raster layer.

THRESHOLD

number - Threshold for different route. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

...

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.
