Hi, everyone, I've got two versions of a FGDB polygon feature class(original and revised), I'd like to use ChangeDetector two find the differences between them. But the output result was very odd, some added or deleted polygons looked exactly and had seem attributes. I only created a topology dataset to fix overlaps and gaps in revised data, I figureed this is issue. Then I tried the same workflow with my backup data. As expected, I got less output through added and deleted port, and most odd results were not there any more.
I browsed FME Knowledge Center about ChangeDetector and I find this question is most likely the reason caused my problem. But all my data are stored in FGDB not SDE. And all FGDBs have same parameters which are default.
Further more, my data is stored in longitude and latitude, if a CoordinteRounder is needed I'm not sure how to set the precision parameter.
