Infuriating! I have an Arc map (Arc9.3.1) that shows the spatial distribution of observation points contained in a shapefile that was created from an xcel spreadsheet. Noticing an entry error for the co-ordinates of one point, I have changed the co-rods in the shape file using the Editor function in Arc. I have saved the edits and stopped editing but the point still plots in the original incorrect location in the map. I have checked the co-ordinates in the edited shapefile where the corrected co-ords are registered; I have cremoved the shapefile from the map and brought it in again. I have close Arc and reopened the map. The observation point still plots in the incorrect position, even though the new correct co-ordinates can be seen in the shapefile table. Can anyone help with this madness?
