Has anyone ever noticed if the output from FME as opposed to an output from an ArcGIS model is more granular? Here's why I ask ... When I run an ArcGIS model that does an overlay of 3 polygon layers on a leases polygon layer the final output has about 11000 polygon records. When I do the same steps in FME using the AreaOnAreaOverlayer I end up with about 14000 polygon records. What's funny is the acreage total is about the same. I'm thinking the FME tools may be more literal in the way they do processing.
Any ideas off the top of your heads why this may be happening?
