I have a polygon with 4 attributes (1,2,3 or 4). In the process of creating this polygon (merge/erase/union), there were gaps left between 1 and 2, with some of the gaps having slivers of 3 or 4.

How do I snap polygon 1 to polygon 2, without moving polygon 2, and simultaneously remove any slivers 3 and 4, using ArcGIS Pro?

  • I have reduced the scope of your question to ArcGIS Pro so if you also want to ask about ArcGIS Desktop 10.6 then that can be done in a separate question. The answer to one may or may not be the same as for the other.

  • I think your question would benefit from a picture of the input and desired output for a few polygons.

  • I think this would take a bit of coding, are you looking for code that does this? Jun 3, 2018 at 23:16

Check out the Integrate tool it will make features coincident if they are within a specified distance:

Maintains the integrity of shared feature boundaries by making features coincident if they fall within the specified x,y tolerance. Features that fall within the specified x,y tolerance are considered identical or coincident.

  • It does make them coincident, but both polygons move. Mar 22, 2018 at 2:58
