Hello Martin That was *fast*!
OK, to answer your first question: for what I know, everybody over here writes data using decimal degrees (no such crazy things as 10.30 == 10°30' as far as I know!) So, I guess to override that DMS directive and treat everything as decimal degrees, I should try your workaround, right? I'll get back to you when I've done that. Thanks again for the almost realtime feedback!
