Label | Explanation | Data Type |
Input Points | The point features used for calculating watersheds. These are referred to as pour points, because it is the location at which water pours out of the watershed. | Feature Set |
Point Identification Field (Optional) | An integer or string field used to identify to the input points. The default is to use the unique ID field. | String |
Snap Distance (Optional) | The maximum distance to move the location of an input point. Interactive input points and documented gage locations may not exactly align with the stream location in the DEM. This parameter allows the service to move the point to a nearby location with the largest contributing area. By default, the snapping distance is calculated as the resolution of the source data multiplied by 5. | String |
Snap Distance Units (Optional) | The linear units specified for the snap distance.
| String |
Data Source Resolution (Optional) | Specifies the source data resolution that will be used in the analysis. The values are an approximation of the spatial resolution of the digital elevation model used to build the foundation hydrologic database. Since many elevation sources are distributed in units of arc seconds, an approximation is provided in meters for easier understanding.
| String |
Generalize (Optional) | Specifies whether the output watersheds will be smoothed into simpler shapes or conform to the cell edges of the original DEM.
| Boolean |
Return Snapped Points (Optional) | Determines if a point feature at the watershed's pour point will be returned. If snapping is enabled, this might not be the same as the input point.
| Boolean |
Derived Output
Label | Explanation | Data Type |
Output Watershed | The output watershed. | Feature Set |
Output Snapped Points | The output snapped points. | Feature Set |
