Hi

 

I am trying to merge about 15 sets containing information about green infrastructure in to one singular dissolved, multipart polygon.

 

In ArcGIS I would use the Merge geoprocessing tool to all the the layers into one, select all the features and merge them. Finally I would do a dissolve.

 

In FME I have fed all the input layers into a Dissolve transformer (dropping attibutes), fed the area output port to an aggregator. I am unsure what to do with remnants - I have fed Unused Areas from the remnants port to the Aggregator but not interior lines (I presume these are the dividing lines that have been removed in the dissolve?) - is this correct?

 

Many thanks

Yes, you only need the Area. The Remnants are the leftovers of lines that are removed.
