Having the same problem at a fully patched ArcGIS 10.2.2 Standard w/64bit background geoprocessing on Windows 7 Pro 64bit SP1
The attached image displays a point "Identify." Notice the Lat_DD and Lon_DD attributes (used to create the points) do not match the "Location" values.
The attached File Geodatabase (zipped into a single file) contains two tables:
- GCP_Table - Used the Lat_DD and Lon_DD fields to create the XY layer.
- CreatedByMakeXY - Notice the XY Coordinate system is set to what I used to create the event layer
BTW - Same results using ArcGIS 10.0
Is this enough information? Thank you
