Hello everyone,
I’m working in FME 2023.2 and using the ChangeDetector to compare features coming from PostGIS and ArcGIS Online (AGOL). Visually, the geometries look identical (no edits were actually made), but the ChangeDetector keeps reporting that a large number of features have updated geometry.
I’ve already tried:
- Turning on Lenient Geometry Matching in the ChangeDetector
- Setting Vector Tolerance to a small value (like 0.0001 - Takes more time)
While that helped reduce the count somewhat, I’m still seeing a substantial amount of features flagged as updated when they shouldn’t be.
I suspect it might have to do with differences in ring orientation, vertex ordering, or the presence of Z/M values, but I’m not certain how best to address these discrepancies so the ChangeDetector recognizes that there hasn’t really been a change.
Any suggestions or advice on how to make the geometry truly match (or be treated as unchanged) would be greatly appreciated. Thanks in advance!
