I think the gamma parameter for omerc isn't yet supported in Proj.4.
......
Hermann Peifer gave the solution to use the +rot_conv flag instead.
REPLY:
Indeed, if I'm not mistaken, in PROJ only an alpha parameter is supported.
But if you use +rot_conv, then the alpha is taken as a gamma.
In Evenden's libproj software both alpha and gamma can be given
independently.
By the way: is Kertau on the Everest 1930 ellipsoid or on the Modified
Everest 1830 ellipsoid?
