Hi,

 

 

I'm trying to buffer a set of municipality polygons.The buffer is only needed on the external edges i.e. the ones that have a coastal edge and the buffer for each polygon musn't overlap with it's neighbour.  I've had a go with the buffer and AreaOnArea overlayer transformers but am getting stuck on how to resovle the overlaps. The below diagram is what I'm trying to acheive, starting with the green boundary polygons. Can anyone suggest an approach to this.

 

 

 

 

Many Thanks

 

 

James

Hi,

 

 

you can remove the buffer overlaps in several ways, but one alternative could be to use the AreaOnAreaOverlayer and then remove all parts where "_overlaps >= 2".

 

 

Other alternatives could involve the Clipper or the Intersector.
