qgis_meshcontours: QGIS algorithm - Export contours

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

QGIS algorithm - Export contours

Description

QGIS Algorithm provided by QGIS (native c++) Export contours (native:meshcontours). Creates contours as vector layer from mesh scalar dataset This algorithm creates contours as a vector layer from a mesh scalar dataset.

Usage

qgis_meshcontours(
  INPUT = qgisprocess:::qgis_default_value(),
  DATASET_GROUPS = qgisprocess:::qgis_default_value(),
  DATASET_TIME = qgisprocess:::qgis_default_value(),
  INCREMENT = qgisprocess:::qgis_default_value(),
  MINIMUM = qgisprocess:::qgis_default_value(),
  MAXIMUM = qgisprocess:::qgis_default_value(),
  CONTOUR_LEVEL_LIST = qgisprocess:::qgis_default_value(),
  CRS_OUTPUT = qgisprocess:::qgis_default_value(),
  OUTPUT_LINES = qgisprocess:::qgis_default_value(),
  OUTPUT_POLYGONS = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	mesh - Input mesh layer. Path to a mesh layer.
DATASET_GROUPS	meshdatasetgroups - Dataset groups. .
DATASET_TIME	meshdatasettime - Dataset time. .
INCREMENT	number - Increment between contour levels. 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.
MINIMUM	number - Minimum contour level. 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.
MAXIMUM	number - Maximum contour level. 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.
CONTOUR_LEVEL_LIST	string - List of contours level. String 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.
CRS_OUTPUT	crs - Output coordinate system. CRS as an auth ID (e.g. 'EPSG:3111'). CRS as a PROJ4 string (e.g. 'PROJ4:…'). CRS as a WKT string (e.g. 'WKT:…'). Path to a layer. The CRS of the layer is used..
OUTPUT_LINES	sink - Exported contour lines. Path for new vector layer.
OUTPUT_POLYGONS	sink - Exported contour polygons. 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.
