QGIS algorithm - Tile index

Description

QGIS Algorithm provided by GDAL Tile index (gdal:tileindex). —————- Arguments —————- LAYERS: Input files Argument type: multilayer PATH_FIELD_NAME: Field name to hold the file path to the indexed rasters Default value: location 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 ABSOLUTE_PATH: Store absolute path to the indexed rasters 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 PROJ_DIFFERENCE: Skip files with different projection reference 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 TARGET_CRS: Transform geometries to the given CRS (optional) Argument type: crs Acceptable values: - CRS as an auth ID (e.g. 'EPSG:3111') - CRS as a PROJ4 string (e.g. 'PROJ4:…') - CRS as a WKT string (e.g. 'WKT:…') - Path to a layer. The CRS of the layer is used. CRS_FIELD_NAME: The name of the field to store the SRS of each tile (optional) 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 CRS_FORMAT: The format in which the CRS of each tile must be written Default value: 0 Argument type: enum Available values: - 0: Auto - 1: Well-known text (WKT) - 2: EPSG - 3: Proj.4 Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' OUTPUT: Tile index Argument type: vectorDestination Acceptable values: - Path for new vector layer

Usage

gdal_tileindex(
  LAYERS = qgisprocess:::qgis_default_value(),
  PATH_FIELD_NAME = qgisprocess:::qgis_default_value(),
  ABSOLUTE_PATH = qgisprocess:::qgis_default_value(),
  PROJ_DIFFERENCE = qgisprocess:::qgis_default_value(),
  TARGET_CRS = qgisprocess:::qgis_default_value(),
  CRS_FIELD_NAME = qgisprocess:::qgis_default_value(),
  CRS_FORMAT = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

LAYERS	multilayer - Input files. .
PATH_FIELD_NAME	string - Field name to hold the file path to the indexed rasters. 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.
ABSOLUTE_PATH	boolean - Store absolute path to the indexed rasters. 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.
PROJ_DIFFERENCE	boolean - Skip files with different projection reference. 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.
TARGET_CRS	crs - Transform geometries to the given CRS. CRS as an auth ID (e.g. 'EPSG:3111'). CRS as a PROJ4 string (e.g. 'PROJ4:…'). CRS as a WKT string (e.g. 'WKT:…'). Path to a layer. The CRS of the layer is used..
CRS_FIELD_NAME	string - The name of the field to store the SRS of each tile. 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.
CRS_FORMAT	enum of ⁠("Auto", "Well-known text (WKT)", "EPSG", "Proj.4")⁠ - The format in which the CRS of each tile must be written. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
OUTPUT	vectorDestination - Tile index. Path for new vector 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.
