raster
- Target Area. Path to a raster layer.
number
- Target X coordinate. 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.
number
- Target Y coordinate. 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.
raster
- Elevation. Path to a raster layer.
raster
- Sink Routes. Path to a raster layer.
rasterDestination
- Upslope Area. Path for new raster layer.
enum
of ("(0) Deterministic 8", "(1) Deterministic Infinity", "(2) Multiple Flow Direction", "(3) Multiple Triangular Flow Directon", "(4) Multiple Maximum Downslope Gradient Based Flow Directon")
- Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number
- Convergence. 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()
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
.
logical specifying if parameter .quiet
for qgisprocess::qgis_run_algorithm()
Default value is TRUE
.
logical specifying if messages from qgisprocess::qgis_run_algorithm()
should be printed (TRUE
) or not (FALSE
). Default value is FALSE
.
