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 Since nad2bin is no longer available null.lla has been replaced by its binary counterpart null.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.

2019-01-01Split ISO19111 C API docs into functions and typesKristian Evers
The rest of the C API is structured such that type definitions goes into one page and functions to another. This commit makes sure the same is done for the C bindings to the ISO19111 C++ API by defining two doxygen groups in proj.h, which is then organized into the proper pages with Sphinx and breathe.

Implement RFC 2: Initial integration of "GDAL SRS barn" work
2018-11-14Implement RFC 2: Initial integration of "GDAL SRS barn" workEven Rouault
This work mostly consists of: - a C++ implementation of the ISO-19111:2018 / OGC Topic 2 "Referencing by coordinates" classes to represent Datums, Coordinate systems, CRSs (Coordinate Reference Systems) and Coordinate Operations. - methods to convert between this C++ modeling and WKT1, WKT2 and PROJ string representations of those objects - management and query of a SQLite3 database of CRS and Coordinate Operation definition - a C API binding part of those capabilities This is all-in-one squashed commit of the work of https://github.com/OSGeo/proj.4/pull/1040

With projects.h not being available to outside users anymore we need to define PJ_UNITS, PJ_ELLPS, PJ_PRIME_MERIDIANS and PJ_OPERATIONS elsewhere. Related pj_get_*_ref() functions have been removed in favour of their proj_ namespaced counterparts. char pointers have been changed to const char pointers.
