Chopper

Breaks input features into points, lines, or areas. Chopped features contain the same set of vertices as input features.

This is useful when outputting to a format that has limitations on the number of coordinates in each feature. It can also be used to crudely simplify complex objects.

All new features have the same attributes as the original feature had and are output via the Output port. The optional chopping indicator attribute can be used to distinguish output features which were chopped from output features which were not.

Usage Notes

Input arcs are stroked prior to chopping. If the chopping operation does not modify a stroked arc, the arc is unstroked and will be output untouched.

Area features are chopped in such a way as to preserve the original area of the feature. That is, the original area feature is cut into smaller areas, which if dissolved together, would match the original area. New vertices may be introduced into the area feature as it is chopped.
