grass_r_texture: QGIS algorithm - r.texture

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

QGIS algorithm - r.texture

Description

QGIS Algorithm provided by GRASS r.texture (grass:r.texture). Generate images with textural features from a raster map.

Usage

grass_r_texture(
  input = qgisprocess:::qgis_default_value(),
  method = qgisprocess:::qgis_default_value(),
  size = qgisprocess:::qgis_default_value(),
  distance = qgisprocess:::qgis_default_value(),
  .s = qgisprocess:::qgis_default_value(),
  .a = qgisprocess:::qgis_default_value(),
  output = qgisprocess:::qgis_default_value(),
  GRASS_REGION_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_REGION_CELLSIZE_PARAMETER = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

input	raster - Name of input raster map. Path to a raster layer.
method	enum of ⁠("asm", "contrast", "corr", "var", "idm", "sa", "se", "sv", "entr", "dv", "de", "moc1", "moc2")⁠ - Textural measurement method(s). Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
size	number - The size of moving window (odd and = 3). 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.
distance	number - The distance between two samples (= 1). 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.
.s	boolean - Separate output for each angle (0, 45, 90, 135). 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. Original algorithm parameter name: -s.
.a	boolean - Calculate all textural measurements. 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. Original algorithm parameter name: -a.
output	folderDestination - Texture files directory. Path for an existing or new folder.
GRASS_REGION_PARAMETER	extent - GRASS GIS region 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..
GRASS_REGION_CELLSIZE_PARAMETER	number - GRASS GIS region cellsize (leave 0 for default). 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.
...	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.
