sagang_sinkdrainageroutedetection: QGIS algorithm - Sink drainage route detection

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

QGIS algorithm - Sink drainage route detection

Description

QGIS Algorithm provided by SAGA Next Gen Sink drainage route detection (sagang:sinkdrainageroutedetection). —————- Arguments —————- ELEVATION: Elevation Argument type: raster Acceptable values: - Path to a raster layer SINKROUTE: Sink Route Argument type: rasterDestination Acceptable values: - Path for new raster layer 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_sinkdrainageroutedetection(
  ELEVATION = qgisprocess:::qgis_default_value(),
  SINKROUTE = 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

ELEVATION	raster - Elevation. Path to a raster layer.
SINKROUTE	rasterDestination - Sink Route. Path for new raster layer.
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.
