gdal_triterrainruggednessindex: QGIS algorithm - Terrain Ruggedness Index (TRI)

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

QGIS algorithm - Terrain Ruggedness Index (TRI)

Description

QGIS Algorithm provided by GDAL Terrain Ruggedness Index (TRI) (gdal:triterrainruggednessindex). —————- Arguments —————- INPUT: Input layer Argument type: raster Acceptable values: - Path to a raster layer BAND: Band number Default value: 1 Argument type: band Acceptable values: - Integer value representing an existing raster band number COMPUTE_EDGES: Compute edges Default value: false Argument type: boolean Acceptable values: - 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 OPTIONS: Additional creation options (optional) Default value: Argument type: string Acceptable values: - 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: Terrain Ruggedness Index Argument type: rasterDestination Acceptable values: - Path for new raster layer

Usage

gdal_triterrainruggednessindex(
  INPUT = qgisprocess:::qgis_default_value(),
  BAND = qgisprocess:::qgis_default_value(),
  COMPUTE_EDGES = qgisprocess:::qgis_default_value(),
  OPTIONS = qgisprocess:::qgis_default_value(),
  OUTPUT = 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.
COMPUTE_EDGES	boolean - Compute edges. 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.
OPTIONS	string - Additional 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 - Terrain Ruggedness Index. 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.
