handle dynamic vertical datums, and instanciate them properly from database
2020-10-10WKT2:2019 import/export: handle DATUM (at top level object) with PRIMEMEven Rouault
This is a peculiarity of the WKT grammar. Despite ISO 19111 saying that the prime meridian is a component of the datum, in WKT, they are placed at the same level, for backward compatibility with earlier WKT versions. So handle exporting and importing that. The fix is only for situation where DATUM is the top level object (was working fine otherwise), which is a uncommon use case. And to limit the amount of issue, on export emit the prime meridian only if it is not Greenwich.

WGS 84 (Gxxxx), etc.) when possible
2020-10-06Database: "minimal" update to EPSG v10.003Even Rouault
Content mostly unchanged since v9.9 This update is "minimal" in that it mostly reflects the removal of the 'area' table, replaced now by 'extent', 'scope' and 'usage' Other new aspects of EPSG v10 are left aside.

2020-09-26Implement ellipsoidal formulation of +proj=ortho (fixes #397)Even Rouault
- Map ESRI 'Local' to +proj=ortho when Scale_Factor = 1 and Azimuth = 0 - Map ESRI 'Orthographic' to a PROJ WKT2 'Orthographic (Spherical)' which maps to +proj=ortho +f=0 to froce spherical evaluation
2020-09-17createOperations(): tune sorting of transformations so that the ones with ↵Even Rouault
greater 'version numbers' are prefered over other ones, when all other comparison criteria are equal. Helps with Amersfoort RD New to EPSG:4326
2020-09-17Adjust createBoundCRSToWGS84IfPossible() and operation filtering (for POSGAR ↵Even Rouault
2007 to WGS84 issues) (fixes #2356) - We make createBoundCRSToWGS84IfPossible() more restrictive. If there are more than one Helmert transformation from the CRS to WGS 84 covering the area of use of the CRS, we do not create a BoundCRS / +towgs84 - In createOperations() filtering, we are less aggressive in discarding operations that have the same area of use but worse accuracy. We do it only if they involve more transformation steps. We now get: ``` $ projinfo EPSG:5340 -o PROJ PROJ.4 string: +proj=longlat +ellps=GRS80 +no_defs +type=crs $ projinfo -s EPSG:5340 -t EPSG:4326 --spatial-test intersects --summary Candidate operations found: 2 EPSG:9264, POSGAR 2007 to WGS 84 (2), 0.5 m, Argentina EPSG:5351, POSGAR 2007 to WGS 84 (1), 1.0 m, Argentina ```
