I am trying to dissolve polygons that are spread out across a region. ArcMap's ModelBuilder will dissolve these polygons into a single, multi-part feature. How can I get FME to do this same thing? I have reviewed the Dissolver and FeatureMerger transformers without any luck.

Perhaps you are looking for aggregator , give it a try .

  • Jorge, thanks for the suggestion. Aggregator does seem to do the trick, although it doesn't dissolve lines between polygons. It will work for what I need for now though, thanks!

    @denim_dan Use the dissolver before the aggregator. This should dissolve the lines between the boundaries and then combine the results into a single multi polygon

  • @MickyT thanks Micky you were right; I was able to aggregate and then dissolve just fine, thanks for the suggestion.
