sagang_dtmfilterslopebased: QGIS algorithm - Dtm filter (slope-based)

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

QGIS algorithm - Dtm filter (slope-based)

Description

QGIS Algorithm provided by SAGA Next Gen Dtm filter (slope-based) (sagang:dtmfilterslopebased). —————- Arguments —————- INPUT: Grid to filter Argument type: raster Acceptable values: - Path to a raster layer RADIUS: Search Radius Default value: 2 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 TERRAINSLOPE: Approx. Terrain Slope Default value: 30 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 STDDEV: Use Confidence Interval 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 GROUND: Bare Earth Argument type: rasterDestination Acceptable values: - Path for new raster layer NONGROUND: Removed Objects Argument type: rasterDestination Acceptable values: - Path for new raster layer

Usage

sagang_dtmfilterslopebased(
  INPUT = qgisprocess:::qgis_default_value(),
  RADIUS = qgisprocess:::qgis_default_value(),
  TERRAINSLOPE = qgisprocess:::qgis_default_value(),
  STDDEV = qgisprocess:::qgis_default_value(),
  GROUND = qgisprocess:::qgis_default_value(),
  NONGROUND = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Grid to filter. Path to a raster layer.
RADIUS	number - Search Radius. 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.
TERRAINSLOPE	number - Approx. Terrain Slope. 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.
STDDEV	boolean - Use Confidence Interval. 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.
GROUND	rasterDestination - Bare Earth. Path for new raster layer.
NONGROUND	rasterDestination - Removed Objects. Path for new raster layer.
...	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.
