Tool description

The Trim Coverage tool is used to remove features in a coverage that are not desired based on their location. The tool trims all arcs in a selected coverage to the polygons of another selected coverage. Arcs can be trimmed to preserve the portions of the arcs inside or outside of the trimming polygons. The user also specifies a buffer distance to allow the trimming to not retain the intersection points

A specific applications of this tool would be to trim extracted features that are outside of the desired simulation domain. Another application would be to clear out feature arcs that are inside the extents of a predominant feature such as a main river channel.

The tool allows for trimming data to features that are either inside or outside of the desired polygons.

Input parameters

  • Input coverage containing arcs to be trimmed – This will bring up the Select Feature Coverage dialog, where a feature coverage to trim can be selected.
  • Input coverage containing polygons to trim by – This will bring up the Select Feature Coverage dialog, where a feature coverage to trim can be selected.
  • Trimming option – Trim to inside or Trim to outside.
    • "Trim to inside" – Trim to inside only keeps portions of the arcs that are inside of the polygons. .
    • "Trim to outside" – Trim to outside only keeps the arc portions that are outside of the polygons.
  • Trimming buffer distance – Enter a value that defines an offset (either inside if trimming to inside, or outside if trimming to outside) of the trimming polygons. This can be used to keep the results from being too close to the trimming polygon(s).

Output parameters

  • Output coverage – specify the name of the coverage to be created (representing the trimmed arcs).
