Snap Neighboring Catchments Tool

The 'Snap Neighboring Catchments' tool is accessed via the 'Special tools' menu on the Catchments rib-bon.

This tool can be used to update the geometry of catchments on the map, to ensure that neighboring catchments are correctly snapped. It is especially useful to prepare catchments before attempting to merge them with the 'Network simplification' tool, because distant catchments cannot be merged even if the distance between them is negligeable.

The tool will edit catchments when their boundaries are within the specified distance from another catchment.

Clicking 'Highlight' will show on the map the catchments which will be updated. Clicking 'Snap' will execute the tool and update the catchments.
