```Hi,

I've seen your text, and its been very help full.

I was asking this question because I've got a military map in my possession that states that it is in a Gauss Conformal projection and that the central meridian is at 23*East and also using wgs84 spheroid.

That central meridian of 23*East is not an interval of a Central meridian of a 6* or 3* zone width system

Both conventions exist, and a few more national ones.
See http://www.cartotalk.com/lofiversion/index.php?t3633.html for a discussion, and some more links.
In summary, if someone says "Gauss-Krüger zone number n", then you have not the slightest idea what it means...

Need some info.

I've got some information from the web that indicates that Gauss-Kruger divides zones of width 3*. I also found text saying its is the same as UTM with zones of 6* and that only the scale factor changes to 1.0 . Does any one know the real answer?

If I do a UTM with a scalefactor of 1.0 will that be a gauss kruger projection?

Anyone?

thanks
