2020-02-06Fix ingestion of +proj=cea with +k_0Even Rouault
Fixes #1881 Digging into the implementation of proj=cea, it appears that k_0 and lat_ts are intended to be exclusive ways of specifying the same concept. EPSG only models the variant using lat_s. So if k_0 is found and lat_ts is absent, compute the equivalent value of lat_ts from k_0. Note: k_0 should normally be in the [0,1] range. In case creative users would use something outside, we raise an exception, even if the cea implementation could potentially deal with any k_0 value. Hopefully this is a (reasonable) limitation that will address nominal use cases.

Not certain whether this is appropriate when you are dealing with lists of grids, but it definitely helps for a single grid.
2020-01-16Explain why sweep axis affects geolocationGerrit Holl
In the note on the sweep angle, add a line explaining why the sweep angle ultimately affects the geolocation, as it is not immediately or trivially obvious to see why it should matter what the outer or inner gimbal is. To this end, link to a post on Mathematics Stack Exchange that explains this very well.

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.
