2020-02-05Fix performance issue, affecting projinfo EPSG:7842Even Rouault
Fixes #1913 AuthorityFactory::createBetweenGeodeticCRSWithDatumBasedIntermediates() issued a complex SQL query that pushes the SQLite3 query plan optimizer to its limits. Was working reasonably with sqlite 3.11, but not with later versions. So put less constraints in the main query and do post-processing checks and auxiliary requests to avoid such issues. For some unknown reason, this slightly slows down a bit execution time of the whole test_cpp_api binary (~ 10%), but couldn't come with something better, despite trying many variations of the main SQL query. It seems that in the general case the non-filter LEFT JOIN on the supersession table helped, except on this EPSG:7842 case.

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.

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.

packages Due to potential future shift to GTiff format, we don't want users of PROJ 6.3 being pointed to grids they won't be able to use.
