This question already has an answer here:

I am trying to dissolve poly from a shapefile with unary_union and at times I am left with a poly that looks like this:StrangePoly

You can see the lingering line geometries left inside of the poly. I have been able to drill down to the xy coords of the exterior and build a new polygon from that. This has removed the chatter that is shown in the interior of the poly, but using the exterior coords leaves me with a problem detailed in the image below that is a zoom from the red box above:

WonkyLine

There are a couple of lines like this that remain in the exterior ring, is there a way that I can remove them?

  • Is there a link to the duplicate? I'd really like to know how this was resolved. Thanks – rickD Aug 21 '16 at 21:42
  • the link above fixed the problem I was seeing using the join_style keyword in multiple buffers. Good stuff! – rickD Nov 23 '16 at 3:12
