QGIS algorithm - r.series.accumulate

QGIS Algorithm provided by GRASS r.series.accumulate (grass:r.series.accumulate). Makes each output cell value an accumulation function of the values assigned to the corresponding cells in the input raster map layers.

Arguments

input

multilayer - Input raster layer(s). .

lower

raster - Raster map specifying the lower accumulation limit. Path to a raster layer.

upper

raster - Raster map specifying the upper accumulation limit. Path to a raster layer.

method

enum of ("gdd", "bedd", "huglin", "mean") - This method will be applied to compute the accumulative values from the input maps. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

scale

number - Scale factor for input. 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.

shift

number - Shift factor for input. 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.

range

range - Ignore values outside this range (min,max). Two comma separated numeric values, e.g. '1,10'.

limits

range - Lower and upper accumulation limits (lower,upper). Two comma separated numeric values, e.g. '1,10'.

.n

boolean - Propagate NULLs. 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. Original algorithm parameter name: -n.

.f

boolean - Create a FCELL map (floating point single precision) as output. 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. Original algorithm parameter name: -f.

output

rasterDestination - Accumulated. Path for new raster layer.

GRASS_REGION_PARAMETER

extent - GRASS GIS region 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..

GRASS_REGION_CELLSIZE_PARAMETER

number - GRASS GIS region cellsize (leave 0 for default). 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.

GRASS_RASTER_FORMAT_OPT

string - Output Rasters format options (createopt). 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.

GRASS_RASTER_FORMAT_META

string - Output Rasters format metadata options (metaopt). 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.

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.
