Question
Re-combining polygons as rings in a polygon
I have input polygons that consist of multiple disconnected rings (as islands) and I am generalising them and removing islands of less than a certain area. I am using Generalizer, DonutHoleExtractor, SpatialFilter and DonutBuilder to do this and it works well, but the resulting layers are now individual polygons. I want to combine the polygons as rings in single polygons based on a unique ID. Can someone recommend a method of doing this please?

Hi,
Have a look at the aggregator, you can combine all the polygons into one aggegate.
