Re: OpenMap demo question

Hi Oscar,

Happy new year to you!

I didn't get the same longitude, my value was 1.8346552. But the
conversion still didn't work to go back the other way, giving different
UTM coordinate values than when I started.

When I started with lat/lons, though, the conversions did work out
properly. Is it possible that your coordinates aren't valid UTM
coordinates, or that the Northing value doesn't make sense for your
zone? Not that I know any better, I'm just wondering.
