  moisture_live = qgisprocess:::qgis_default_value(),
  velocity = qgisprocess:::qgis_default_value(),
  direction = qgisprocess:::qgis_default_value(),
  slope = qgisprocess:::qgis_default_value(),
  aspect = qgisprocess:::qgis_default_value(),
  elevation = qgisprocess:::qgis_default_value(),
  base_ros = qgisprocess:::qgis_default_value(),
  max_ros = qgisprocess:::qgis_default_value(),
  direction_ros = qgisprocess:::qgis_default_value(),
  spotting_distance = qgisprocess:::qgis_default_value(),
  GRASS_REGION_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_REGION_CELLSIZE_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_OPT = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_META = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

model	raster - Raster map containing fuel models. Path to a raster layer.
moisture_1h	raster - Raster map containing the 1-hour fuel moisture (%). Path to a raster layer.
moisture_10h	raster - Raster map containing the 10-hour fuel moisture (%). Path to a raster layer.
moisture_100h	raster - Raster map containing the 100-hour fuel moisture (%). Path to a raster layer.
moisture_live	raster - Raster map containing live fuel moisture (%). Path to a raster layer.
velocity	raster - Raster map containing midflame wind velocities (ft/min). Path to a raster layer.
direction	raster - Name of raster map containing wind directions (degree). Path to a raster layer.
slope	raster - Name of raster map containing slope (degree). Path to a raster layer.
aspect	raster - Raster map containing aspect (degree, CCW from E). Path to a raster layer.
elevation	raster - Raster map containing elevation (m, required for spotting). Path to a raster layer.
base_ros	rasterDestination - Base ROS. Path for new raster layer.
max_ros	rasterDestination - Max ROS. Path for new raster layer.
direction_ros	rasterDestination - Direction ROS. Path for new raster layer.
spotting_distance	rasterDestination - Spotting Distance. 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.
