)raster - Elevation. Path to a raster layer.
rasterDestination - Visible Sky. Path for new raster layer.
rasterDestination - Sky View Factor. Path for new raster layer.
rasterDestination - Sky View Factor (Simplified). Path for new raster layer.
rasterDestination - Terrain View Factor. Path for new raster layer.
rasterDestination - Average View Distance. Path for new raster layer.
number - Maximum Search Radius. 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.
number - Number of Sectors. 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.
enum of ("(0) cell size", "(1) multi scale") - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Multi Scale Factor. 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()
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.
