[Proj] System 42/83 (S42/83)

[Clifford J Mugnier]

The DHG has its origin in WWII and was developed by the Germans,
specifically by Dr. Gigas.  It is identical to the UTM with only one
exception:  Scale Factor at Origin is 1.0 and NOT 0.9996 - there is no
other difference (other than the standard ellipsoid for System 42 Datum.
Furthermore, it is the identical system that is termed "Russia Belts."  The
math model is the Gauss-Kruger.

Hello all,

I'm trying to use coordinates in S42/83, a system often used in eastern
Europe
(e.g. Russia) and partially in East-Germany ("Deutsches Heeresgitter").

It's similar to Gauss-Kruger (Gauß-Krüger) (i.e a transverse mercator
projection) but it uses 6 degrees wide stripes instead of 3 degrees.

And its first meridian is at 3E.

Is there a possibility to define these parameters in cs2cs/proj4?

As ellipsoid "Krassovski" is used (+ellps=krass).

Many greetings
Erich
