2020-11-24Add option to allow export of Geographic/Projected 3D CRS in WKT1_GDALEven Rouault
as CompoundCRS with a VerticalCRS being an ellipsoidal height, which is not conformant. But needed for LAS 1.4 that only supports WKT1
2020-11-01projinfo / createObjectsFromName(): support returning a datum ensembleEven Rouault
2020-11-01When reading from database, possibly return VerticalCRS with a DatumEnsembleEven Rouault

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.
2020-10-08Add a AuthorityFactory::createDatumEnsemble() method, and make it inherit ↵Even Rouault
from ObjectUsage as mandated by ISO 19111:2019
2020-08-26proj_create_vertical_crs_ex(): add a ACCURACY option to provide an explicit ↵Even Rouault

Geog2D+GravityRelatedHeight (US .gtx)' method used by Slovakian geoids correctly deal with axis order and unit conversion, to be used as 'standalone'. Also improves when using directly 'Geographic3D to GravityRelatedHeight' method

2020-01-25Implement RFC 5Even Rouault
2020-01-22Merge RFC4 (#1865)Even Rouault
This commit is the result of the squashing of rfc4_dev branch in a single commit. It implements mostly RFC 4 related work. * Grid handling: - remove obsolete and presumably unfinished implementation of grid catalog functionality - all grid functionality is in grids.cpp/.hpp - vertical and horizontal grid shift: rework to no longer load whole grid into memory - remove hgrids and vgrids member from PJ structure, and store them in hgridshift/vgridshift/deformation structures - build systems: add optional libtiff dependency. Must be explicitly disabled if not desired - add support for horizontal and vertical grids in GeoTIFF, if libtiff is available - add GenericShiftGridSet and GenericShiftGrid classes, relying on TIFF grids, that can be used for generic purpose grid-based adjustment - add a +proj=xyzgridshift method to perform geocentric translation by grid. Used for French NTF to RGF93 transformation using gr3df97a.tif grid - deformation: add support for +grids= for GeoTIFF grids - horizontal grid shift: fix failures on points slightly outside a subgrid (fixes #209) * File management: - add a filemanager.cpp/.hpp to deal with file related work - test for legacy proj_api.h fileapi - proj.h: add proj_context_set_fileapi() and proj_context_set_sqlite3_vfs_name() (fixes #866) - add capability to read resource files from the user writable directory * Network access: - build systems: add optional curl dependency - add a curl-based default implementation for network related functionality - proj.h: add C API to control network functionality, and optionaly provide network callbacks - add data/proj.ini with default settings - add a SQLite3 local cache of downloaded chunks - add proj_is_download_needed() and proj_download_file() * Use Win32 Unicode APIs and expect all strings to be UTF-8 (fixes #1765) For backward compatibility, if PROJ_LIB content is found to be not UTF-8 or pointing to a non existing directory, then an attempt at interpretating it in the ANSI page encoding is done. proj_context_set_search_paths() now assumes strings to be in UTF-8, and functions returning paths will also return values in UTF-8.
2019-12-16identify(): take into datum name aliases (fixes #1800)Even Rouault
2019-11-19createOperations(): in some situations, consider when going from A to D ↵Even Rouault
intermediates B and C, such there's a A->B operation and C->D operation, and A and C are not exactly the same CRS but use the same geodetic datum
2019-11-17createOperations(): remove the concept of geodetic_datum_preferred_hubEven Rouault
This was introduced in 63857c92b271bbcd10df0a032304982011acb2a9. Due to the fix done in the previous commit, we can mostly revert the above commit. We just keep the added tests and the custom WGS 84<-->WGS 84 (Gxxxx) null transformations.
2019-11-17findsOpsInRegistryWithIntermediate(): tune it to be able to research ↵Even Rouault
operations that belong to different authorities. Should make the concept of geodetic_datum_preferred_hub introduced some time ago obsolete
2019-11-02Add a geoid_model name in database, use GEOIDMODEL for transformations, add ↵Even Rouault
a proj_create_vertical_crs_ex()
2019-11-02Add tracing framework, and improve createOperations() performanceEven Rouault
2019-10-29Vertical transformations: improve situations similar to transforming from ↵Even Rouault
'NAVD88 (ftUS)' to X, where we now consider the available transformations from 'NAVD88' to X that might exist in the database
2019-09-12Coordinate transformation: improve transformations from/to WGS84 (Gxxxx)Even Rouault
Currently very few transformations from/to WGS84 (Gxxxx) are registered in the EPSG database, and there isn't even transformations between WGS84 EPSG:4326 and those ones. Consequently transformations to those realizations often ended up as no-operation, whereas going through WGS84 EPSG:4326 will bring more meaningful results. So register those EPSG:4326<-->WGS 84 (Gxxx) null transformations, and when having WGS 84 (Gxxx) as source/target, consider EPSG:4326 as an intermediate. This change has no effect on the existing direct transformations from/to WGS 84 (Gxxx).
2019-09-08Use in API and utilities WKT2_2019 instead of WKT2_2018 (fixes #1518)Even Rouault
- 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.

ETRS89 (EPSG:4937), make sure that the vgridshift is applied first (ie on Amersfoort datum) before the hgridshift
2019-04-22proj_create(): add support for compoundCRS and concatenatedOperation named ↵Even Rouault
from their components Support following syntaxes: - OGC URN combining references for compoundCRS: e.g. "urn:ogc:def:crs,crs:EPSG::2393,crs:EPSG::5717" - its GDAL shortcut: e.g. "EPSG:2393+5717" - OGC URN combining references for concatenated operations: e.g. "urn:ogc:def:coordinateOperation,coordinateOperation:EPSG::3895,coordinateOperation:EPSG::1618"

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.
