2019-03-24Doc: consistently use +opt and bracketsChris Mayo
+opt represents one parameter. An ellipsis indicates additional instances of the previous parameter may be given. Spaces are used between parameters and before an ellipsis, not purely to format brackets. See man(1) SYNOPSIS conventions.

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.

2019-02-04Remove all traces of nad2bin and nad2nadKristian Evers
The source material for the default grids used by PROJ has been moved to the proj-datumgrid repository. For that reason it is no longer necessary to include the nad2bin program in the PROJ repository and source distribution. From now on the nad2bin application will be kept in the proj-datumgrid repo. Previously the null grid was generated by running nad2bin on the null.lla file. Since nad2bin is no longer available null.lla has been replaced by its binary counterpart null. This file will be distributed and installed alongside PROJ. Build scripts and documenation has been adjusted so that nad2bin is not mentioned anywhere. Additionally all references to nad2nad has been removed as well. nad2nad has not been part of the PROJ distribution for quite some time so this has been long overdue.
