I'm using ArcMap, and i've got two large polygon layers that are of the same area (Canada).

One layer is made up of 2,500 polygons, the other is 14. when I clip (using one of the 14 layers) I will get slivers of some of the 2,500 polygons along the edges of my clip. this tells me that they arent exactly on the same lines.

Is there a way to reshape the 14-polygon layer, using some sort of "snap-to-closest" editing tool? or do I need to go edge by edge along the entire thing to edit the layer?

    Have you tried using the Integrate - Data Management tool? – mdholl6188 Feb 25 '19 at 21:33

    or union/clip then eliminate resources.arcgis.com/en/help/main/10.2/index.html#//… (advanced license required). Be very careful with the integrate tool, it works on the input data and can absolutely ruin your geometries with no hope of undo if you use a tolerance too large, I strongly suggest making a backup of your data before using integrate. – Michael Stimson Feb 25 '19 at 23:13
  • @mdholl6188 (how do i tag michael?) it looks like Integrate uses a midpoint between the two boundaries, is that correct? One of my layers (the one with 2,500 parts) is the "correct" layer, so Eliminate should work? also, there are a few boundaries that do NOT share edges with the "correct" layer, will those stay where they should be? – threkar Feb 27 '19 at 14:54
