sagang_flowaccumulationqmofesp: QGIS algorithm - Flow accumulation (qm of esp)

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Flow accumulation (qm of esp)

Description

QGIS Algorithm provided by SAGA Next Gen Flow accumulation (qm of esp) (sagang:flowaccumulationqmofesp). —————- Arguments —————- DEM: DEM Argument type: raster Acceptable values: - Path to a raster layer FLOW: Contributing Area Argument type: rasterDestination Acceptable values: - Path for new raster layer PREPROC: Preprocessing Default value: 1 Argument type: enum Available values: - 0: (0) none - 1: (1) fill sinks temporarily - 2: (2) fill sinks permanently Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' DZFILL: Fill Increment Default value: 0.01 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

Usage

sagang_flowaccumulationqmofesp(
  DEM = qgisprocess:::qgis_default_value(),
  FLOW = qgisprocess:::qgis_default_value(),
  PREPROC = qgisprocess:::qgis_default_value(),
  DZFILL = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

DEM	raster - DEM. Path to a raster layer.
FLOW	rasterDestination - Contributing Area. Path for new raster layer.
PREPROC	enum of ⁠("(0) none", "(1) fill sinks temporarily", "(2) fill sinks permanently")⁠ - Preprocessing. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
DZFILL	number - Fill Increment. 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.
