[mapguide-users] Longitude, Zone and Reference meridian

[Orest Halustchak]

Hi Don,

I'm assuming you mean UTM zone?

For UTM, given the zone number the formula for central meridian is: zone * 6 - 183

UTM zones are 6 degrees wide.

>From this, you can generate the math for going in the other direction.

Thanks,
Orest.

Hi folks
There is a linear relationship among Longitude, Zone and Reference meridian, does anyone know any formula to calculate Zone and Reference Meridian if I know Longitude?
Thanks
