2020-12-21Implementing the NKG transformations in proj.dbKristian Evers
This adds the NKG 2008 and 2020 transformations to proj.db. The NKG transformations offers transformations between global reference frames and the national realisations of ETRS89 in Denmark, Estonia, Finland, Latvia, Lithuania, Norway and Sweden. The 2008 transformations are already implemented in the NKG 2008 file but will now be more accessible with the modern API. The 2020 transformations are new to PROJ and offers and updated version of the 2008 transformations using a new and improved deformation model (eu_nkg_nkgrf17vel.tif). A 2020 version of the NKG transformations are currently not available for Norway but will in all likelyhood be included at a later point in time.

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.
2020-09-17Adjust 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 ```

2020-03-16Merge branch 'master' into add_proj_get_suggested_operationEven Rouault
2020-03-13Add proj_get_suggested_operation()Even Rouault
Return the index of the operation that would be the most appropriate to transform the specified coordinates. This operation may use resources that are not locally available, depending on the search criteria used by proj_create_operations(). This could be done by using proj_create_operations() with a punctual bounding box, but this function is faster when one needs to evaluate on many points with the same (source_crs, target_crs) tuple.

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

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.
