raster
- Elevation. Path to a raster layer.
rasterDestination
- Convergence Index. Path for new raster layer.
boolean
- Gradient. 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.
enum
of ("(0) direction to the center cell", "(1) center cell's aspect direction")
- Difference. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number
- Radius (Cells). 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) no distance weighting", "(1) inverse distance to a power", "(2) exponential", "(3) gaussian")
- Weighting Function. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number
- Power. 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
- Bandwidth. 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
.
