2021-10-06proj_create_crs_to_crs() + proj_trans(): fix when non-Greenwich prime ↵Even Rouault
meridian is involved This fixes a regression introduced in 7af1d5741da08d9546b907e0da2c21c54c61b27 / PROJ 7.2.0 where reprojection of area of use was broken when the source/target CRS did not use Greenwich as prime meridian. Fixes https://lists.osgeo.org/pipermail/gdal-dev/2021-October/054764.html Now with the fix: - using grid: $ echo 286415 431434 | PROJ_NETWORK=ON src/cs2cs -d 4 EPSG:20790 EPSG:3763 86412.4262 131434.1706 0.0000 - not using it: $ echo 286415 431434 | src/cs2cs -d 4 EPSG:20790 EPSG:3763 86412.5265 131433.8561 0.0000

transformation (#2882) Fixes #2779
2021-09-30proj_factors(): accept P to be a projected CRS (fixes #2854)Even Rouault
Updated doc: Starting with PROJ 8.2, the P object can be a projected CRS, for example instantiated from a EPSG CRS code. The factors computed will be those of the map projection implied by the transformation from the base geographic CRS of the projected CRS to the projected CRS. The input geodetic coordinate lp should be such that lp.lam is the longitude in radian, and lp.phi the latitude in radian (thus independently of the definition of the base CRS, if P is a projected CRS).
2021-08-26Pipeline instanciation: fix performance issues on huge (broken) strings ↵Even Rouault
which managed somehow to cause nested pipelines not caught due to some non-roundtripability in parsing/serializing. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=37489
2021-06-17proj_trans/cs2cs: If two operations have the same accuracy, use the one that ↵Even Rouault
is contained within a larger one Relates to https://github.com/OSGeo/gdal/issues/3998 Before that change, cs2cs on a NAD83(HARN) to WGS84 transformation would use the "NAD83(HARN) to WGS 84 (1)" transformation (a null Helmert shift) that is valid for whole US, including non-CONUS areas, even when used on points located on CONUS that has a "NAD83(HARN) to WGS 84 (3)" transformation (non-null Helmert shift) with same accuracy (1m). But if doing EPSG:2874 "NAD83(HARN) / California zone 5 (ftUS)" to WGS84, we would use this later "NAD83(HARN) to WGS 84 (3)" transformation because the area of use of EPSG:2874 restricts to CONUS. This isn't consistant. With that change, we now have more consistent behavior, even if it can be argued which of the 2 transformations is the best... $ echo 34 -120 | src/cs2cs -d 8 EPSG:4326 "NAD83(HARN)" | src/cs2cs "NAD83(HARN)" EPSG:2874 5955507.74 1828410.98 0.00 $ echo 34 -120 | src/cs2cs EPSG:4326 EPSG:2874 5955507.74 1828410.98 0.00

PROJ_SPATIAL_CRITERION_PARTIAL_INTERSECTION if area is specified" This reverts commit ebe3425bf66287e004958eb53976d3837f88b9e1. It was found to break gdalwarp usage in https://github.com/OSGeo/gdal/issues/3695 when passing a bbox that is quite large.

Gone are pj_malloc, pj_calloc, pj_dalloc and pj_dealloc. Their primary function as API memory functions in proj_api.h is no longer there and the other use as a workaround for old errno problems is no longer valid either. Replaced with malloc and free across the codebase.

2020-04-12Add proj_degree_input() and proj_degree_output()Kristian Evers
Equivalent to proj_angular_input() and proj_angular_output() but checking for degree units instead. proj_create_crs_to_crs() rarely, if ever, returns pipelines that has radians as input or output so using proj_angular_*() is not a useful check for io units of pipelines. These two new functions should make life a bit easier for users that generally store there angular coordinates in radians. Closes #2027
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.

2020-02-27proj_create_crs_to_crs(): avoid potential reprojection failures when ↵Even Rouault
reprojecting area of use to source and target CRS Was found with https://github.com/OSGeo/PROJ/pull/1989 when using cs2cs EPSG:4937 EPSG:31258+5778 - We do not need to do vertical transformation in that context. This failed here because the Austrian grids have nodata value outside of the shape of Austria, so the edges of the grids are mostly nodata values. - And we should avoid grid-based transformations too.

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.
2019-12-25Modify verbosity level of some debug/trace messagesEven Rouault
- unitconvert, ell_set and helmert were using debug level, which is too verbose. Using trace instead - proj_trans() was using trace to indicate the operation it selects. Changing it to debug

2019-09-26proj_create_crs_to_crs(): fix when there are only transformations with ↵Even Rouault
ballpark steps Currently we would discard all operations, resulting in a PJ object with zero candidates. Better use those operations if nothing better is available. Was seen on transforming from ETRS89 / UTM zone 31N + EGM96 height to WGS 84 (G1762). The horizontal transformation from ETRS89 to WGS 84 (G1762) is a ballpark one.

is passed to the function
2019-09-04proj_create_crs_to_crs_from_pj(): make the PJ* arguments const PJ*Even Rouault
This will make the life of C++ users using the C API slightly easier. There's no ABI or API backward compatibility issue in doing that change as constness of arguments is not retained in the C ABI, and any non-const object passed as argument is implicitly converted as a const object if that is what is mentionned in the argument list.
2019-08-23Add proj_create_crs_to_crs_from_pj()Even Rouault
I've been frustrated a number of times with proj_create_crs_to_crs() not accepting a PJ* object for the source and target CRS. And thus constraining to go back to WKT2 in a artificial way.
