AreaOnAreaOverlayer - Sharp Edges

Hello there,

 

I have a question regarding the AreaOnAreaOverlayer. When I use that transformer to clean my polygons I get some polygons with really sharp edges. Is there a way to avoid this? I guess it is random on how it decides which polygon to cut from another polygon when they overlap, right?

 

Thanks very much in advance for your help!

Are those edges visible in the original data as well?

If so, you can try cleaning up the data by using the tolerance parameter in the AreaOnAreaOverlayer (FME 2019) or a Snapper.

A SpikeRemover or AreaGapAndOverlapCleaner transformer may also help clean that up.
