I'm using the add xy data feature to import an excel table. When I display XY data arcmap interprets the data as meters instead of decimal degrees. I wind up with data points in the Atlantic Ocean instead of the Sierras. I've tried changing the angular and display units of the map to decimal degrees but my points are still out in the Atlantic. Is there a way to change the untis from meters to decimal degrees or will I have to convert decimal degrees into meters in excel before I import my data?
