I have a tabular data set that contains eastings and northings and LAT and LONG data. I check some points manually with the ArcGIS "go to xy" point tool and they al appear to be in the correct place on a base map. However, after numerous attempts at bringing the data into arc and using "display xy data" to place them on the map I still end up with the data being projected in the wrong place and to the wrong scale.
What could be causing this, and how do I fix it?
I am operating with ArcGIS, Displaying in Decimal Degrees, WGS 1984 WM (Data frame coord system)
Projected Coordinate System: Name: WGS_1984_World_Mercator
Geographic Coordinate System: Name: GCS_WGS_1984
