gdal_contour: QGIS algorithm Contour

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

QGIS algorithm Contour

Description

QGIS Algorithm provided by GDAL Contour (gdal:contour)

Usage

gdal_contour(
  INPUT = qgisprocess::qgis_default_value(),
  BAND = qgisprocess::qgis_default_value(),
  INTERVAL = qgisprocess::qgis_default_value(),
  FIELD_NAME = qgisprocess::qgis_default_value(),
  CREATE_3D = qgisprocess::qgis_default_value(),
  IGNORE_NODATA = qgisprocess::qgis_default_value(),
  NODATA = qgisprocess::qgis_default_value(),
  OFFSET = qgisprocess::qgis_default_value(),
  EXTRA = qgisprocess::qgis_default_value(),
  OUTPUT = qgisprocess::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Input layer. Path to a raster layer.
BAND	band - Band number. Integer value representing an existing raster band number.
INTERVAL	number - Interval between contour lines. A numeric value.
FIELD_NAME	string - Attribute name (if not set, no elevation attribute is attached). String value.
CREATE_3D	boolean - Produce 3D vector. 1 for true/yes. 0 for false/no.
IGNORE_NODATA	boolean - Treat all raster values as valid. 1 for true/yes. 0 for false/no.
NODATA	number - Input pixel value to treat as "nodata". A numeric value.
OFFSET	number - Offset from zero relative to which to interpret intervals. A numeric value.
EXTRA	string - Additional command-line parameters. String value.
OUTPUT	vectorDestination - Contours. Path for new vector 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.
