I should probably have added that you can get a number of the variables you start off with from : http://www.ordnancesurvey.co.uk/oswebsite/gps/information/ coordinatesystemsinfo/guidecontents/guidea.html and http://www.ordnancesurvey.co.uk/oswebsite/gps/information/ coordinatesystemsinfo/guidecontents/index.html might be useful to read around the subject. It might look complex, but don't let it put you off. Also, you can get JavaScript code to do just this from the URL below, which would be a good starting point. http://www.movable-type.co.uk/scripts/latlong-gridref.html Regards, Carl. -- http://mail.python.org/mailman/listinfo/python-list
