[OSRS-PROJ] Rotated coordinates

[Iwan Holleman]

Hi Christian,

It is possible! I use it to calculate the coordinates of the gridpoints
of our NWP model HIRLAM.
The proj-string I use for this is:

 +proj=ob_tran +o_proj=eqc +o_lat_p=30.0 +a=57.29578 +lon_0=-15.0

In this way: XY represent the (longitude and latitude) of the rotated
grid in degrees, and LL the unrotated longitude and latitude . The
rotation is specified by o_lat_p and lon_o.

Best regards,

Iwan Holleman
