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

QGIS algorithm - i.atcorr

Description

QGIS Algorithm provided by GRASS i.atcorr (grass:i.atcorr). Performs atmospheric correction using the 6S algorithm.

  input = qgisprocess:::qgis_default_value(),
  range = qgisprocess:::qgis_default_value(),
  elevation = qgisprocess:::qgis_default_value(),
  visibility = qgisprocess:::qgis_default_value(),
  parameters = qgisprocess:::qgis_default_value(),
  rescale = qgisprocess:::qgis_default_value(),
  output = qgisprocess:::qgis_default_value(),
  .i = qgisprocess:::qgis_default_value(),
  .r = qgisprocess:::qgis_default_value(),
  .a = qgisprocess:::qgis_default_value(),
  .b = qgisprocess:::qgis_default_value(),
  GRASS_REGION_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_REGION_CELLSIZE_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_OPT = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_META = 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.
range	range - Input imagery range (0,255). Two comma separated numeric values, e.g. '1,10'.
elevation	raster - Input altitude raster map in m (optional). Path to a raster layer.
visibility	raster - Input visibility raster map in km (optional). Path to a raster layer.
parameters	file - Name of input text file. Path to a file.
rescale	range - Rescale output raster map (0,255). Two comma separated numeric values, e.g. '1,10'.
output	rasterDestination - Atmospheric correction. Path for new raster layer.
.i	boolean - Output raster map as integer. 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: -i.
.r	boolean - Input raster map converted to reflectance (default is radiance). 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: -r.
.a	boolean - Input from ETM+ image taken after July 1, 2000. 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.
.b	boolean - Input from ETM+ image taken before July 1, 2000. 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: -b.
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.
GRASS_RASTER_FORMAT_OPT	string - Output Rasters format options (createopt). 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.
GRASS_RASTER_FORMAT_META	string - Output Rasters format metadata options (metaopt). 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.
...	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.
