QGIS Algorithm provided by QGIS (native c++) Raster rank (native:rasterrank). Performs a cell-by-cell analysis in which output values match the rank of a sorted list of overlapping cell values from input layers. This algorithm performs a cell-by-cell analysis in which output values match the rank of a sorted list of overlapping cell values from input layers. The output raster will be multi-band if multiple ranks are provided. If multiband rasters are used in the data raster stack, the algorithm will always perform the analysis on the first band of the rasters.

)multilayer - Input raster layers. .
string - Rank(s) (separate multiple ranks using commas). 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.
enum of ("Exclude NoData from values lists", "Presence of NoData in a values list results in NoData output cell") - NoData value handling. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
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..
number - Output cell size. 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.
crs - Output 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..
rasterDestination - Ranked. Path for new raster layer.
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.
