Hi there, I am working on a data clean up model. Many thin areas and remnants have been cleaned up but I can't figure out how to this last thing.

There are some thin areas that connect on both sides to a large and very complex polygon. (See image)

Does anyone have a suggestion for how to remove these type of areas? So only the thin parts have to be removed.

​@wrijs Would one of the NeighbourFinder tools work in this case? If you know the minimum gap between the polys this should work. Or finding the Longest Edge.
 

 

Hi ​@wrijs ,

This could work depending on the condition.

  1. Snapper (Snapping Type: Segment Snapping) : Modify the boundary lines in the thin parts to completely collinear lines - a kind of self-intersection.
  2. GeometryValidator (Issue to Detect: Self-Intersections in 2D) : Detect and remove the collinear lines to repair the polygons.

​@takashi that worked perfectly, thank you
