QGIS algorithm - Raster boolean AND

Description

QGIS Algorithm provided by QGIS (native c++) Raster boolean AND (native:rasterbooleanand). Calculates the boolean AND for a set of input raster layers This algorithm calculates the boolean AND for a set of input rasters. If all of the input rasters have a non-zero value for a pixel, that pixel will be set to 1 in the output raster. If any of the input rasters have 0 values for the pixel it will be set to 0 in the output raster. The reference layer parameter specifies an existing raster layer to use as a reference when creating the output raster. The output raster will have the same extent, CRS, and pixel dimensions as this layer. By default, a NoData pixel in ANY of the input layers will result in a NoData pixel in the output raster. If the 'Treat NoData values as false' option is checked, then NoData inputs will be treated the same as a 0 input value.

Usage

qgis_rasterbooleanand(
  INPUT = qgisprocess:::qgis_default_value(),
  REF_LAYER = qgisprocess:::qgis_default_value(),
  NODATA_AS_FALSE = qgisprocess:::qgis_default_value(),
  NO_DATA = qgisprocess:::qgis_default_value(),
  DATA_TYPE = qgisprocess:::qgis_default_value(),
  CREATE_OPTIONS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT

multilayer - Input layers. .

REF_LAYER

raster - Reference layer. Path to a raster layer.

NODATA_AS_FALSE

boolean - Treat NoData values as false. 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.

NO_DATA

number - Output NoData value. 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.

DATA_TYPE

enum of ⁠("Byte", "Int16", "UInt16", "Int32", "UInt32", "Float32", "Float64", "CInt16", "CInt32", "CFloat32", "CFloat64", "Int8")⁠ - Output data type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

CREATE_OPTIONS

string - 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 - Output layer. 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.
