QGIS algorithm - i.tasscap

Description

QGIS Algorithm provided by GRASS i.tasscap (grass:i.tasscap). Performs Tasseled Cap (Kauth Thomas) transformation.

Usage

grass_i_tasscap(
  input = qgisprocess:::qgis_default_value(),
  sensor = 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

multilayer - Input rasters. Landsat4-7: bands 1,2,3,4,5,7; Landsat8: bands 2,3,4,5,6,7; MODIS: bands 1,2,3,4,5,6,7. .

sensor

enum of ⁠("landsat4_tm", "landsat5_tm", "landsat7_etm", "landsat8_oli", "modis")⁠ - Satellite sensor. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

output

folderDestination - Output 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.
