2021-04-23Database: update to EPSG v10.019Even Rouault
Non-trivial updates: - some vertical CRS are now encoded as DerivedVerticalCRS. e.g EPSG:8228 "NAVD88 height (ft)", with base EPSG:5703 "NAVD88 height". As we don't have support in our PROJ db model for DerivedVerticalCRS, modify the import script to 'resolve' the derivation up to the original datum. - Method EPSG:1069 'Change of Vertical Unit' is no longer used. It is replaced by a generic-purpose EPSG:1104 method that doesn't take any conversion factor. And generic conversions EPSG:7812 and EPSG:7813 are now used in concatenated operations, which require code changes as well.

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
