QGIS algorithm - Create random raster layer (geometric distribution)

Description

QGIS Algorithm provided by QGIS (native c++) Create random raster layer (geometric distribution) (native:createrandomgeometricrasterlayer). Generates a raster layer for given extent and cell size filled with geometrically distributed random values. By default, the values will be chosen given a probability of 0.5. This can be overridden by using the advanced parameter for mean value. The raster data type is set to Integer types (Integer16 by default). The geometric distribution random values are defined as positive integer numbers. A floating point raster will represent a cast of integer values to floating point.

Usage

qgis_createrandomgeometricrasterlayer(
  EXTENT = qgisprocess:::qgis_default_value(),
  TARGET_CRS = qgisprocess:::qgis_default_value(),
  PIXEL_SIZE = qgisprocess:::qgis_default_value(),
  OUTPUT_TYPE = qgisprocess:::qgis_default_value(),
  PROBABILITY = qgisprocess:::qgis_default_value(),
  CREATE_OPTIONS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

EXTENT	extent - Desired extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..
TARGET_CRS	crs - Target CRS. 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..
PIXEL_SIZE	number - Pixel size. 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.
OUTPUT_TYPE	enum of ⁠("Integer16", "Unsigned Integer16", "Integer32", "Unsigned Integer32", "Float32", "Float64")⁠ - Output raster data type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
PROBABILITY	number - Probability. 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.
CREATE_OPTIONS	string - Creation options. 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.
OUTPUT	rasterDestination - Output raster. 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.
