Hi all,
I have a polygon file. There area many small polygon like 0.00001, 0.0022,...
I want to eliminate small polygon into bigger polygon based on query area.
Could you tell me how to do it in FME? Thank you

Yes. I have tried AreaGapAndOverlapCleaner but it's only using between polygons. And other polygon is not adjacent, it can't gap fill

If i'm understanding correctly, these small polygons touch a large polygon?
Heres a rough outline of something similar i've done...
- Give each polygon a UUID (UUIDGenertor)
- set a threshold for 'small' and 'large' polygons, split these into separate branches (Tester)
- using a NeighborFinder feed your 'small' polgons into the Base and the 'large' polygons into the Candidate
- Set it so you're only finding one neighbor, also enable GenerateList and select only the previously generate UUID
- Out the matched port you will now have your 'small' polygons with a UUID (in the list) for the nearest large polygon. Extract this UUID and replace the original UUID value with the one from the list
- Assuming that the polygons are touching, you can now feed this into a Dissolver with the Group By set to the UUID field and they will dissolve

Thank you for replying.
In the step 5, I'm not understanding. I attached a demo model that I tried to step 5.
- Could you explain more the step 5 (Out the matched port you will now have your 'small' polygons with a UUID (in the list) for the nearest large polygon. Extract this UUID and replace the original UUID value with the one from the list
Thank you so much!

Hi @hkingsbury ,
In my case, I have fields: plot_uuid, area.
I want to dissolve area <0.03 into the same plot_uuid. I tried but it does not dissolve. I attached my model in the below.
That I want:
Could you tell me how to make it the same photo? thank you
