I imported an excel spreadsheet of a couple hundred lat long coordinates that I wanted to become points. The majority of them were projected correctly except for a few were in the wrong hemisphere. I went in and manually added a (-) in front of the longitude to bring the points to the western hemisphere (it seems that the (-) was lost in translation or my file had errors).
The problem is that the attribute table now has the correct coordinates but the points are still in the eastern hemisphere.
I manually changed the coordinates in the attribute table during an editing session but the new coordinates have not been displayed on the map. Is there a way of changing the points coordinates in ArcMap without uploading an new edited excel sheet?
