2020-11-01projinfo / createObjectsFromName(): support returning a datum ensembleEven Rouault

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.
2020-09-17createOperations(): 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 ```

2020-02-27Make tests independent of proj-datumgridEven Rouault
Fixes #1984 - Copy BETA2007.gsb, MD, alaska, conus, ntf_r93.gsb, ntv1_can.dat grids from proj-datumgrid to data/tests. - Replace a couple uses of nzgd2kgrid0005.gsb in tests by ntf_r93.gsb - Add downsampled/subsetted versions of egm96_15.gtx as tests/egm96_15_downsampled.gtx and ntv2_0.gsb as tests/ntv2_0_downsampled.gsb This results in a few changes in expected results - Simpify travis/install.sh due to less configurations to test This results in a hopefully acceptable increase of the proj-X.Y.Z.tar.gz from 2.9 to 5.3 MB

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.

2020-01-05Make sure tests pass if extra grids are presentEven Rouault
Should fix the issue reported in https://lists.osgeo.org/pipermail/proj/2020-January/009188.html Some extra north-american grids present in data/ can affect the results of some tests, so create a data/for_tests/ subdirectory in which we copy only select grids.
2019-12-25Database: tune accuracy of Canadian NTv1 file w.r.t NTv2Even Rouault
As on import of EPSG, we remove the supersession of Canadian NTv1 file w.r.t NTv2 (because the default behaviour of PROJ is to ignore superseded operations). However the NTv1 operation is advertized with an accuracy of 1m, whereas NTv2 is advertized with 1.5m. Consequently on areas where both files are valid, and if both files are available, NTv1 would be selected. So as a workaround, worsen the NTv1 accuracy to 2m so that NTv2 is used in priority.
