QGIS algorithm - Coverage of categories

Source: R/sagang_coverageofcategories.R

QGIS Algorithm provided by SAGA Next Gen Coverage of categories (sagang:coverageofcategories). —————- Arguments —————- CLASSES: Categories Argument type: raster Acceptable values: - Path to a raster layer COVERAGES: Coverages Argument type: rasterDestination Acceptable values: - Path for new raster layer LUT: Classification (optional) Argument type: source Acceptable values: - Path to a vector layer LUT_VAL: Value Argument type: field Acceptable values: - The name of an existing field - ; delimited list of existing field names LUT_MAX: Maximum Value Argument type: field Acceptable values: - The name of an existing field - ; delimited list of existing field names LUT_NAME: Class name Argument type: field Acceptable values: - The name of an existing field - ; delimited list of existing field names NO_DATA: Mark No Coverage as No-Data Default value: true 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 DATADEPTH: Data Depth Default value: 1 Argument type: enum Available values: - 0: (0) 1-byte - 1: (1) 2-byte - 2: (2) 4-byte - 3: (3) 8-byte Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX: Output extent (optional) Argument type: extent Acceptable values: - A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105' - Path to a layer. The extent of the layer is used. TARGET_USER_SIZE: Cellsize Default value: 100 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

Arguments

CLASSES

raster - Categories. Path to a raster layer.

COVERAGES

rasterDestination - Coverages. Path for new raster layer.

LUT

source - Classification. Path to a vector layer.

LUT_VAL

field - Value. The name of an existing field. ; delimited list of existing field names.

LUT_MAX

field - Maximum Value. The name of an existing field. ; delimited list of existing field names.

LUT_NAME

field - Class name. The name of an existing field. ; delimited list of existing field names.

NO_DATA

boolean - Mark No Coverage as No-Data. 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.

DATADEPTH

enum of ("(0) 1-byte", "(1) 2-byte", "(2) 4-byte", "(3) 8-byte") - Data Depth. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

TARGET_USER_XMIN_TARGET_USER_XMAX_TARGET_USER_YMIN_TARGET_USER_YMAX

extent - Output extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used.. Original algorithm parameter name: TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX.

TARGET_USER_SIZE

number - Cellsize. 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.

...

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.
