qgis_exportaddgeometrycolumns: QGIS algorithm - Add geometry attributes

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

QGIS algorithm - Add geometry attributes

Description

QGIS Algorithm provided by QGIS Add geometry attributes (qgis:exportaddgeometrycolumns). This algorithm computes geometric properties of the features in a vector layer. It generates a new vector layer with the same content as the input one, but with additional attributes in its attributes table, containing geometric measurements. Depending on the geometry type of the vector layer, the attributes added to the table will be different.

Usage

qgis_exportaddgeometrycolumns(
  INPUT = qgisprocess:::qgis_default_value(),
  CALC_METHOD = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
CALC_METHOD	enum of ⁠("Layer CRS", "Project CRS", "Ellipsoidal")⁠ - Calculate using. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
OUTPUT	sink - Added geom info. 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.
