<PRE>
 Projection     : Transverse Mercator (Gauss-Krueger)
 General class  : cylindrical
 Characteristics: conformal
                : rectangular coordinates (U.S.A.; Britain)
 Earth model    : ellipsoid or sphere
</PRE>
Defining the MAPUNITS:
<P>
<PRE>
 MapUnits &quot;tm&quot;       ! Standard name
 MapUnits &quot;tm e0&quot;    ! Standard name and ellipsoid
</PRE>
Other parameters:
<P>
<PRE>
 TrueOriginLongitude &quot;central_meridian&quot;        ! Required -+- True origin
 TrueOriginLatitude  &quot;latitude_of_origin&quot;      ! Required /
 FalseEasting        &quot;false_easting&quot;           ! Optional, default is zero
 FalseNorthing       &quot;false_northing&quot;          ! Optional, default is zero
 Scale               &quot;scale_at_cent_meridian&quot;  ! Optional, default is one
</PRE>
Possible errors:
<P>
<PRE>
 E334, &quot;Point cannot be projected&quot; - In converting from geographic 
        coordinates to projection coordinates, the point projects 
        into infinity
 E330, &quot;Calculation failed to converge to a solution&quot; - In converting 
        from projection coordinates to geographic coordinates, the 
        conversion failed to converge to a solution
