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.

Clean up time handling in helmert and deformation
2019-02-14deformation: Replace +t_obs with +dtKristian Evers
The +t_obs parameter was confusing for users since it effectively overwrote the observation time in input coordinates. To make it more clear what is the operation is doing, users are now required to directly specify the time span for which they wish to apply a given deformation. The parameter +dt has been added for that purpose. The new parameter is mutually exclusive with +t_epoch. +dt is used when deformation for a set amount of time is needed and +t_epoch is used (in conjunction with the observation time of the input coordinate) when deformation from a specific epoch to the observation time is needed.

2019-02-14Reverse direction of deformation operations/transformations/deformationKristian Evers
Changed the direction of dt-calculation to follow the same convention as helmert. Changed from dt = t_c - t_obs to dt = t_obs - t_c, which effectively reverses the direction of the operation. Existing projstrings using deformation can simply reverse the direction of the operation to achieve the same results as before this commit.
2019-02-13Add push and pop operationsKristian Evers
This commit introduces the concept of a pipeline coordinate stack in which components of coordinates can be saved and loaded from. This makes it possible to moved values from one step of a pipeline to another, effectively overwriting parts of the output from a given step.
2019-02-11Make tmerc an alias for etmerc. (#1234)Kristian Evers
* Make tmerc an alias for etmerc This switches the algorithm used in tmerc to the Poder/Engsager tmerc algorithm. The original tmerc algorithm of Evenden/Snyder origin can still be accessed by adding the +approx flag when initializing a tmerc projection. The +approx flag can also be used when initializing UTM projections, in which case the Evenden/Snyder algorithm is used as well. If a tmerc projection is instantiated on a spherical earth the Evenden/Snyder algorithm is used as well since the Poder/Engsager algorithm is only defined on the ellipsoid. +proj=etmerc can still be instantiated for backwards compatibility reasons.
