Arguments

GRIDS

multilayer - Values. .

WEIGHTS

multilayer - Weights. .

RESAMPLING

enum of ("(0) Nearest Neighbour", "(1) Bilinear Interpolation", "(2) Bicubic Spline Interpolation", "(3) B-Spline Interpolation") - Resampling. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

MEAN

rasterDestination - Arithmetic Mean. Path for new raster layer.

MIN

rasterDestination - Minimum. Path for new raster layer.

MAX

rasterDestination - Maximum. Path for new raster layer.

RANGE

rasterDestination - Range. Path for new raster layer.

SUM

rasterDestination - Sum. Path for new raster layer.

SUM2

rasterDestination - Sum2. Path for new raster layer.

VAR

rasterDestination - Variance. Path for new raster layer.

STDDEV

rasterDestination - Standard Deviation. Path for new raster layer.

STDDEVLO

rasterDestination - Mean less Standard Deviation. Path for new raster layer.

STDDEVHI

rasterDestination - Mean plus Standard Deviation. Path for new raster layer.

PCTL

rasterDestination - Percentile. Path for new raster layer.

PCTL_VAL

number - Percentile. 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.
