2021-10-08WKT concatenated operation parsing: fix when a axis order reversal ↵Even Rouault
conversion is the first or last operation (fixes #2890)
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.

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 ```
