Hi all,
I have a polygon file that have field area, plot_uuid. I want to dissolve small polygon area <0.03 into the same plot_uuid.
Could you tell me how to make it?
In the below photo, 2 small polygon (yellow and green) will merge into large polygon that I want in the right photo.
Thank you

The Dissolver has a Group By option where you can select one or more attributes to perform that action on. So if you select the plot_uuid attribute all polygons that share a boundary and have the same value for that attribute will be dissolved.

I want to keep area >0.03 ha and I want to dissolve area <0.03 into plot_uuid the same.
If I dissolve by groupe by plot_uuid, they will merge together plot_uuid the same.
So I want to ask how to the way to keep area >0.03 and dissolve area <0.03 with plot_uuid large polygon?

Use a TestFilter to filter out the small areas, then a SpatialFilter to select the larger ones that have the same plot_uuid *and* touch the small ones and then run those through the Dissolver.
