QGIS algorithm - i.biomass

QGIS Algorithm provided by GRASS i.biomass (grass:i.biomass). Computes biomass growth, precursor of crop yield calculation.

Arguments

fpar

raster - Name of fPAR raster map. Path to a raster layer.

lightuse_efficiency

raster - Name of light use efficiency raster map (UZB:cotton=1.9). Path to a raster layer.

latitude

raster - Name of degree latitude raster map (dd.ddd). Path to a raster layer.

dayofyear

raster - Name of Day of Year raster map (1-366). Path to a raster layer.

transmissivity_singleway

raster - Name of single-way transmissivity raster map (0.0-1.0). Path to a raster layer.

water_availability

raster - Value of water availability raster map (0.0-1.0). Path to a raster layer.

output

rasterDestination - Biomass. 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.
