This option is to load grid(s) that have both the horizontal and vertical velocities in the same file.

2019-12-09isea docs: Rewrite intro and reference to reflect actual projectionKristian Evers
Previous version was describing oea by mistake. It is also a projection by Snyder and the isea docs was based on the paper on the oea projection. This commit fixes that.

2019-10-03ob_tran doc: fix/clarify semantics of o_lat_p/o_lon_pEven Rouault
This is a super confusing topic, but from experiments, and in particular with the example of Fairgrieve projection, o_lat_p and o_lon_p are the coordinates of the North pole of the unrotated geographic CRS expressed in the rotated geographic CRS. This is different from defining a 'new pole', which would be the coordinates of the rotated North pole expressed in the unrotated CRS.
