I am creating multiple ring buffers around polygon areas of interests. Due to their proximity, some of these are overlapping. I would like to dissolve them into joined features.

I have tried dissolve using the buffer distance as dissolve field, but it does not quite get the result I am after:

I would like to keep the inner area on top working towards the outside if that makes sense to get a clean polygon.

I found the below for ArcGIS, but am after a solution in QGIS, if anyone has thoughts?

My mind started working properly and I found the solution right after posting: Dissolve first, then do the buffer...

You can buffer while ticking the 'dissolve' option to do the trick in one round.

    That only seems to be an option for the standard buffer function not the multiple ring buffers?

  • I see the point, you are right and that could become a feature request: I think many users would find a dissolvable multiring buffer a useful function.
