QGIS Algorithm provided by SAGA Next Gen Flow accumulation (parallelizable) (sagang:flowaccumulationparallelizable). —————- Arguments —————- DEM: Elevation Argument type: raster Acceptable values: - Path to a raster layer FLOW: Flow Accumulation Argument type: rasterDestination Acceptable values: - Path for new raster layer UPDATE: Update Frequency Default value: 0 Argument type: number Acceptable values: - 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 METHOD: Method Default value: 2 Argument type: enum Available values: - 0: (0) D8 - 1: (1) Dinfinity - 2: (2) MFD Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' CONVERGENCE: Convergence Default value: 1.1 Argument type: number Acceptable values: - 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.
rasterDestination
- Flow Accumulation. Path for new raster layer.
number
- Update Frequency. 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.
enum
of ("(0) D8", "(1) Dinfinity", "(2) MFD")
- 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
.
