QGIS Algorithm provided by SAGA Next Gen Change a grid's no-data value (sagang:changeagridsnodatavalue). —————- Arguments —————- GRID: Grid Argument type: raster Acceptable values: - Path to a raster layer OUTPUT: Changed Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer TYPE: Type Default value: 0 Argument type: enum Available values: - 0: (0) single value - 1: (1) value range Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' VALUE: No-Data Value Default value: -99999 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 CHANGE: Change 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

raster
- Grid. Path to a raster layer.
rasterDestination
- Changed Grid. Path for new raster layer.
enum
of ("(0) single value", "(1) value range")
- Type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number
- No-Data 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.
boolean
- Change 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.
further parameters passed to qgisprocess::qgis_run_algorithm()
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
.
logical specifying if parameter .quiet
for qgisprocess::qgis_run_algorithm()
Default value is TRUE
.
logical specifying if messages from qgisprocess::qgis_run_algorithm()
should be printed (TRUE
) or not (FALSE
). Default value is FALSE
.
