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.

2019-02-07Add proj_get_crs_info_list_from_database()Even Rouault
This method is intended to be used typically by GUI that lists all possible CRS. What is does could be done by previously existing functions, but it is much faster. It typically runs in less than 0.1s (hot run) versus ~0.5s with the method that consists in enumerating all codes and instanciating a PJ object for each of them.

2019-01-08ISO19111: remove PROJ.5 specific format for CRS (refs #1214)Even Rouault
As discussed in https://github.com/OSGeo/proj.4/issues/1214#issuecomment-452084720, the introduction of a new PROJ.5 format to export CRS using pipeline/unitconvert/axisswap as an attempt of improving the PROJ.4 format used by GDAL and other products is likely a dead-end since it is still lossy in many aspects and can cause confusion with coodinate operations. Consequently the PROJ_5 convention will be identical to PROJ_4 for CRS export. Note: on the import side, I've kept the code that could parse unitconvert and axisswap when building a CRS definition from a pipeline. It is there as a hidden feature as it was kind of a tear to remove that code in case it might still be useful...

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
