PROJ/test/unit/test_util.cpp, branch backport-3082-to-9.0 Forked from https://github.com/OSGeo/PROJ Use in API and utilities WKT2_2019 instead of WKT2_2018 (fixes #1518) 2019-09-08T09:11:03+00:00 Even Rouault even.rouault@spatialys.com 2019-09-04T13:46:13+00:00 024f63731283c0026ad5b4dea4084bc48bbcc6f7 - C API: PJ_GUESSED_WKT2_2019 is added, PJ_GUESSED_WKT2_2018 aliased to it - C API: PJ_WKT2_2019[_SIMPLIFIED] is added, PJ_WKT2_2018[_SIMPLIFIED] alias to it - C++ API: similarly for WKTFormatter::Convention::WKT2_2019[_SIMPLIFIED] Those above changes should be fully backward API and ABI compatible. projinfo changes: - accept WKT2_2019 as value for -o switch. WKT2_2018 is still accepted (undocumented) - output now uses 'WKT2_2019 string:', so might break scripts that would rely on that. Other internal code references to WKT2_2018 changes to WKT2_2019, included in tests.

Implement RFC 2: Initial integration of "GDAL SRS barn" work 2018-11-14T21:48:29+00:00 Even Rouault even.rouault@spatialys.com 2018-11-14T16:40:42+00:00 d928db15d53805d9b728b440079756081961c536 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 
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
