Description

QGIS Algorithm provided by GDAL gdal2xyz (gdal:gdal2xyz). —————- 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 NODATA_INPUT: Input pixel value to treat as NoData (optional) Argument type: number Acceptable values: - 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 NODATA_OUTPUT: Assign specified NoData value to output (optional) Argument type: number Acceptable values: - 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 SKIP_NODATA: Do not output NoData values 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 CSV: Output comma-separated values 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 OUTPUT: XYZ ASCII file Argument type: fileDestination Acceptable values: - Path for new file

Usage

gdal_gdal2xyz(
  INPUT = qgisprocess:::qgis_default_value(),
  BAND = qgisprocess:::qgis_default_value(),
  NODATA_INPUT = qgisprocess:::qgis_default_value(),
  NODATA_OUTPUT = qgisprocess:::qgis_default_value(),
  SKIP_NODATA = qgisprocess:::qgis_default_value(),
  CSV = 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.
NODATA_INPUT	number - Input pixel value to treat as NoData. 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.
NODATA_OUTPUT	number - Assign specified NoData value to output. 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.
SKIP_NODATA	boolean - Do not output NoData 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.
CSV	boolean - Output comma-separated 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.
OUTPUT	fileDestination - XYZ ASCII file. 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.
