Anthony,
If by "Spatial Reference" you mean coordinate system, I'm not sure, and how would I verify that. I've tried all difference types of coordinates Decimal Degrees, MGRS, Easting/Northing. All show up in the same location no matter what order I put them in. Like I said the sample spreadsheet loads with no issue, All points show up in the Pacific NW. I tried to follow the same format as the sample when creating my own test points, but for some reason the point is located in the middle of the Altantic Oceans instead of central Pennsylvania.
I'm not sure where the issue is coming from.
