In my Openlayers2 based project I give the possibility for users to upload their own features in KML file or with a WKT string.
I only want to accept features with ESPG:4326 coordinates. Otherwise a error message should be displayed. "Please use only 4326 coordinates bla bla bla"
The issue is that I can't find any way to identify the input coordinates system to make the necessary condition.
Is there a way to identify the EPSG only with the coordinates?
