With this commit, and the 2 previous ones, given mytest.cpp ``` int main() { PJ* pj = proj_create(nullptr, "+proj=vgridshift +grids=us_nga_egm96_15.tif"); for( int i = 0; i < 5*1000*1000; i++) { PJ_COORD coord; coord.lpz.lam = 0; coord.lpz.phi = 0; coord.lpz.z = 0; proj_trans(pj, PJ_FWD, coord); } return 0; } ``` we get a x2 speedup Before: ``` $ PROJ_LIB=data:$HOME/proj/PROJ-data/us_nga LD_LIBRARY_PATH=src/.libs hyperfine --warmup 1 'taskset -c 11 ./mytest' Benchmark #1: taskset -c 11 ./mytest Time (mean ± σ): 1.950 s ± 0.014 s [User: 1.945 s, System: 0.005 s] Range (min … max): 1.937 s … 1.971 s ``` After: ``` $ PROJ_LIB=data:$HOME/proj/PROJ-data/us_nga LD_LIBRARY_PATH=src/.libs hyperfine --warmup 1 'taskset -c 11 ./mytest' Benchmark #1: taskset -c 11 ./mytest Time (mean ± σ): 984.4 ms ± 3.1 ms [User: 977.0 ms, System: 7.2 ms] Range (min … max): 979.3 ms … 990.5 ms ```

2020-12-12Split coordinateoperation.cpp in many files in iso19111/operation directoryEven Rouault
The big size of coordinateoperation.cpp could require significant amount of RAM to build it with -O2 level, and cause compiler crashes in some environments.

- Map ESRI 'Local' to +proj=ortho when Scale_Factor = 1 and Azimuth = 0 - Map ESRI 'Orthographic' to a PROJ WKT2 'Orthographic (Spherical)' which maps to +proj=ortho +f=0 to froce spherical evaluation

2020-04-19Ingestion of WKT1_GDAL: correctly map 'Cylindrical_Equal_Area'Even Rouault
Map it to 'Lambert Cylindrical Equal Area' / EPSG:9835 non-spherical method, when the ellipsoid is not a sphere. And rationalize the handling of this for other methods with spherical vs non-spherical formulations
2020-03-09Map ESRI Transverse_Mercator_Complex to Transverse MercatorEven Rouault
According to https://gis.stackexchange.com/questions/226679/complex-utm-projection it is highly likely that Transverse_Mercator_Complex corresponds to our extended/enhanced/Poder-Engsager transverse mercator method (etmerc), or something similarly precise. So we can map that to the standard Transverse Mercator method, since etmerc is used for it.

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.

2019-09-08Use 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.

doing geog2D<-->geog3D conversions of same datum Seen when testing transformations between "CR 05" (EPSG:5365) and "CR-SIRGAS" (EPSG:8907) which require going through their corresponding 3D GeogCRS to find a Helmert transformation.
