Snap Outlet Points to Streams
The Snap Outlet Points to Streams tool adjusts vector pour points (outlets) to the nearest stream cell within a user-specified maximum search distance, ensuring accurate alignment for watershed analysis. It prioritizes proximity to the nearest stream, rather than the largest stream by flow accumulation, making it more reliable for precise watershed delineation.
This tool is not limited to a single outlet point. It will move all outlet points not already on a stream to the closest stream within the defined search radius.
Input Parameters
- Input pour points (outlets) coverage: – Select the coverage containing the outlet point(s) to be moved.
- Input raster streams file: – Select the raster file used to extract streams.
- Maximum snap distance in map units: – Enter the distance in map units (feet, meters, etc.) to search for closest stream cell to snap outlet points to. Decimal number.
Output Parameters
- Output coverage name: – Type in a new coverage name for the coverage created after snapping outlet points.
