One possibility could be that ArcGIS is a little fuzzier in the tolerances for what it considers intersecting.So a garden that almost, but not quite intersects the house would not be considered by FME, but would by ArcGIS.
Have the SpatialRelator generate a list (just under the tip@danilo_fme)
In fme2018 you can choose the attribute you want to list (finally!and tx Safe)
Sort (descending) the list by the attriubute you want to test and use ListIndexer with index = 0 to get the value.
(remove list when you are done)
Hi@danilo_fme, thanks for the suggestion, but that's not what I meant, that tells me the max number of related candidates.I need it to pick the maximum attribute from the original Supplier, I'll add a comment to make myself clearer.
Enable this option on transformer SpatialRelator:
After use the other transformer StatisticsCalculator to get the max value from _related_candidates.
thanks,
Danilo
