QGIS algorithm - Breach depressions

Description

QGIS Algorithm provided by SAGA Next Gen Breach depressions (sagang:breachdepressions). —————- Arguments —————- DEM: Elevation Argument type: raster Acceptable values: - Path to a raster layer NOSINKS: Preprocessed Argument type: rasterDestination Acceptable values: - Path for new raster layer MAX_LENGTH: Maximum Breach Channel Length Default value: 50 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 MAX_ZDEC: Maximum Elevation Decrement 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 MIN_ZDROP: Minimum Elevation Drop 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

Usage

sagang_breachdepressions(
  DEM = qgisprocess:::qgis_default_value(),
  NOSINKS = qgisprocess:::qgis_default_value(),
  MAX_LENGTH = qgisprocess:::qgis_default_value(),
  MAX_ZDEC = qgisprocess:::qgis_default_value(),
  MIN_ZDROP = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

DEM

raster - Elevation. Path to a raster layer.

NOSINKS

rasterDestination - Preprocessed. Path for new raster layer.

MAX_LENGTH

number - Maximum Breach Channel Length. 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.

MAX_ZDEC

number - Maximum Elevation Decrement. 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.

MIN_ZDROP

number - Minimum Elevation Drop. 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.
