Result type (Watershed Overlay)

The Watershed Module of a Watershed Overlay performs complex calculations and multiple types of results can be provided.

It is currently only possible to add result child overlays via the configuration wizard, in the step regarding output overlays.

List of Result Types

Result type	Unit	Description
BASE_TYPES	Nominal	Categorization of the individual cells based on how they are processed by the watershed model, displaying which cells are considered to be specific features.
DIRECTION	geo angle (0-360°)	The direction to which rain water would flow.
DISCHARGE_AREAS	Integer	The initial Discharge Areas and propagated to water cells by neighbors and culvert-connections.
WATERSHEDS	Integer	The integer ID of the calculated watershed. NO_DATA if no watershed area was calculated for that particular cell.

Although it is possible to duplicate the overlay, and set the copy of the overlay to a different result type, we strongly advice to use child overlays instead. Downsides of the duplication approach are:

the simulation has to run in full multiple times, causing a severe increase in calculation time.
when changes to the overlay's configuration have to be made those changes need to be made to all water overlays.

Result child overlays are not (re)calculated if either they or their parent is set to inactive.
If a calculation overlay is removed, all result child overlays of that overlay are removed as well. Separate overlays set as child overlays (such as input overlays) of the overlay will not be removed.
