I am Featurejoining the output from a change detector that compares an original layer from ArcGIS Online to a revised layer from my Geodatabase. Note: The AGOL layer was originally published from ArcGIS Pro from the coordinate system WGS 1984 Web Mercator (auxiliary sphere) .
The Featurejoiner transformer rejects the features saying:
“Coordinate system does not match first feature's coordinate system”
Similar to the issue as seen in https://community.safe.com/topic/show?tid=20659&fid=8
When I inspect the original and revised features, my features on AGOL have “SPHERICAL_MERCATOR” and my revised features have “SPHERICAL_MERCATOR_0”
In my workspace, my revised features are reprojected with ESRIReporojector to WGS_1984_Web_Mercator_Auxiliary_Sphere before entering the change detector. They then show a Coord system of “SPHERICAL_MERCATOR_0”. FYI The ESRIProjector does display a warning saying “2.1_EsriReprojector: Ignoring input feature coordinate system `_MGA2020-54_FME_0'. This warning will not be repeated.”
What the heck is the difference between SPHERICAL_MERCATOR & SPHERICAL_MERCATOR_0 ??
The above post I mentioned got around this by using coordinate system removers before the feature joiner and then setting the coordinate system again after.
Do I really need to do that ? Can anyone explain ?
