qgis_rasterlayerstatistics: QGIS algorithm - Raster layer statistics

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

QGIS algorithm - Raster layer statistics

Description

QGIS Algorithm provided by QGIS (native c++) Raster layer statistics (native:rasterlayerstatistics). This algorithm computes basic statistics from the values in a given band of the raster layer.

Usage

qgis_rasterlayerstatistics(
  INPUT = qgisprocess:::qgis_default_value(),
  BAND = qgisprocess:::qgis_default_value(),
  OUTPUT_HTML_FILE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Input layer. Path to a raster layer.
BAND	band - Band number. Integer value representing an existing raster band number.
OUTPUT_HTML_FILE	fileDestination - Statistics. Path for new file.
...	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.

Details

Outputs description

• MAX - outputNumber - Maximum value

• MEAN - outputNumber - Mean value

• MIN - outputNumber - Minimum value

• OUTPUT_HTML_FILE - outputHtml - Statistics

• RANGE - outputNumber - Range

• STD_DEV - outputNumber - Standard deviation

• SUM - outputNumber - Sum

• SUM_OF_SQUARES - outputNumber - Sum of the squares
