QGIS algorithm - Sink removal

Description

QGIS Algorithm provided by SAGA Next Gen Sink removal (sagang:sinkremoval). —————- Arguments —————- DEM: DEM Argument type: raster Acceptable values: - Path to a raster layer SINKROUTE: Sink Route (optional) Argument type: raster Acceptable values: - Path to a raster layer DEM_PREPROC: Preprocessed DEM Argument type: rasterDestination Acceptable values: - Path for new raster layer METHOD: Method Default value: 1 Argument type: enum Available values: - 0: (0) Deepen Drainage Routes - 1: (1) Fill Sinks Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' THRESHOLD: Threshold Default value: false Argument type: boolean Acceptable values: - 1 for true/yes - 0 for false/no - 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 THRSHEIGHT: Threshold Height Default value: 100 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_sinkremoval(
  DEM = qgisprocess:::qgis_default_value(),
  SINKROUTE = qgisprocess:::qgis_default_value(),
  DEM_PREPROC = qgisprocess:::qgis_default_value(),
  METHOD = qgisprocess:::qgis_default_value(),
  THRESHOLD = qgisprocess:::qgis_default_value(),
  THRSHEIGHT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

DEM

raster - DEM. Path to a raster layer.

SINKROUTE

raster - Sink Route. Path to a raster layer.

DEM_PREPROC

rasterDestination - Preprocessed DEM. Path for new raster layer.

METHOD

enum of ⁠("(0) Deepen Drainage Routes", "(1) Fill Sinks")⁠ - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

THRESHOLD

boolean - Threshold. 1 for true/yes. 0 for false/no. 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.

THRSHEIGHT

number - Threshold Height. 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.
