2020-01-23Database: add a geoid_like value for proj_method column of ↵Even Rouault
grid_alternatives, fix related entries and simplify/robustify logic to deal with EPSG 'Geographic3D to GravityRelatedHeight' methods
2020-01-22Database: update to EPSG v9.8.6Even Rouault
Fixes #1867
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.

2019-12-16BoundCRS::identify(): improvements to discard CRS that aren't relevant ↵Even Rouault
(fixes #1801) Fix for ``` projinfo --identify "+proj=utm +zone=48 +a=6377276.345 +b=6356075.41314024 +towgs84=198,881,317,0,0,0,0 +units=m +no_defs +type=crs" ``` to only return BoundCRS of EPSG:3148: 70 % Previously it also returned EPSG:23948 and EPSG:24048 whose projected CRS-only parts where likely matches, but those 2 CRSs don't have a +towgs84=198,881,317,0,0,0,0, so discard them.
2019-12-11createOperations(): make filtering out of 'uninteresting' operations less ↵Even Rouault
aggressive (refs #1787) 'EPSG:1304, Indian 1975 to WGS 84 (2), 5.0 m, Thailand - onshore and Gulf of Thailand' was removed because considered useless w.r.t first result 'EPSG:1812, Indian 1975 to WGS 84 (4), 3.0 m, Thailand - onshore' However the name of the area of use is not completely the same, so might be worth keeping it.

2019-12-02Database: register the BWTA2017.gsb grid (DHDN->ETRS89 for Baden-Wurtemberg)Even Rouault
Relates to https://github.com/OSGeo/proj-datumgrid/pull/65 , https://github.com/OSGeo/proj-datumgrid/issues/22 As EPSG has no entry for it, we create a grid_transformation, as well as a dedicated area of use based on the extent of the grid, under the PROJ authority. With the hope to be able to remove it once EPSG has an entry...

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
2019-11-18createOperations(): fix so that GDA94 -> WGS 84 (G1762) still include a ↵Even Rouault
result through ITRF2008. Was broken in master by the addition of the 'WGS84 -> WGS 84 (Gxxx)' null operations in the PROJ authority

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.

2019-10-30createFromWkt(): be tolerant to missing scale_factor parameter (fixes #1700)Even Rouault
This is invalid WKT, but GDAL 2.4 used to accept it and make a reasonable use of it... Currently we default it to 0 which is non sensical. Better use 1 as GDAL 2.4 did, and emit a warning. Other fix: proj_create_from_wkt() was documented to operate by default in non-strict validation mode, but it was actually in strict mode. So do as documented.

2019-09-26Improve vertical transformation supportEven Rouault
When we had a transformation between a compoundCRS and a target geographicCRS, we did not take into account that in the vertical->other_geog_CRS transformation we used, the other_geog_CRS was an implicit interpolation CRS. Thus before doing vertical adjustment, we must go to this interpolation CRS. The workflow is thus: source CRS -> interpolation CRS + vertical adjustment + interplation CRS -> target CRS
