Parameters
| Direction | Type | Parameter Name | Data Type | Dialog Reference |
|---|---|---|---|---|
| Input | Required | Input DEM | GPRasterLayer | Input elevation raster. |
| Input | Required | Input Draft Sink Polygon | GPFeatureLayer | Feature class that defines real sinks, i.e. areas where water can flow into but not outward. This layer can be created by either selecting relevant sinks in the flat area polygon feature class created by the Characterize DEM tool or by creating a new layer from the selection set. |
