2020-07-08CMake build: Check "target_clones" before useKai Pastor
gcc's "target_clones" and "ifunc" function attributes rely on extensions to the ELF standard. Using them on MinGW causes "error: the call requires 'ifunc', which is not supported by this target". Amends 5396b72.
2020-05-28Implement wink2 inverse by generic inversion of forward methodEven Rouault
- Move the generic method initiated from adams_ws2 to a pj_generic_inverse_2d() method - Use it in adams_ws2 - Use it in wink2 Fixes https://github.com/qgis/QGIS/issues/35512
2020-05-19Implemented IGH Oceanic View (#2226)John Krasting
- The current implementation of the Interrupted Goode Homolosine projection emphasizes land area. This is a compliment projection that emphasizes ocean area. - A value of lon0=-160 produces a reasonable real-world map.

Add square conformal projections from libproject
2020-04-15Add square conformal projections from libprojectKristian Evers
This commit adds five new projections to PROJ: adams_hemi: Adams Hemisphere in a Square adams_wsI: Adams World in a Square I adams_wsII: Adams World in a Square II guyou: Guyou peirce_q: Pierce Quincuncial The code originates from Gerry Evendens libproject and has been adapted to work with modern PROJ. To ensure that the modified code works as intended extensive test data has been created using libproject and sproj so that no errors occured when porting from libproject to PROJ. The test data is wrapped in a gie files. All test cases reproduce results from libproject at the mm level.
2020-04-12Remove old geocent.h/.cpp codeEven Rouault
Last user, apart from transform.cpp, was the SCH projection. Modify it to use cart instead. And move content of geocent.h and .cpp into transform.cpp directly, so that it can be later wiped up easily.

2020-03-28CMake: prefer to use use PROJ_SOURCE_DIR and PROJ_BINARY_DIR (#2100)Mike Taves
* Use instead of CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR * Also PROJECT_SOURCE_DIR and PROJECT_BINARY_DIR, which are similar * Set properties with a list variable rather than a long line * Correction to 'proj_test_set_properties' function, rename ENVIRONMENT: - PROJ_IGNORE_USER_WRITABLE_DIRECTORY (ignored) - PROJ_SKIP_READ_USER_WRITABLE_DIRECTORY (used by filemanager.cpp)

CMake: rename BUILD_LIBPROJ_SHARED to BUILD_SHARED_LIBS
2020-02-21Switch build configuration logic from DISABLE_TIFF to ENABLE_TIFFMike Taves
* Autotools interface should be the same, but different ./configure --help * For CMake, the option should be -DENABLE_TIFF=NO (default is YES) * Use TIFF_ENABLED and CURL_ENABLED variables, based on option and outcome * Reword some messages and add hints * Move -DTIFF_ENABLED and -DCURL_ENABLED from global add_definitions() to target_compile_definitions(), which is recommended practice * Minor spelling and style consistency around SQLITE_VERSION check
2020-02-21CMake: rename BUILD_LIBPROJ_SHARED to BUILD_SHARED_LIBSMike Taves
* Deprecate BUILD_LIBPROJ_SHARED, but still use it as an alias for now * Rename BUILD_LIBPROJ_SHARED_DEFAULT to BUILD_SHARED_LIBS_DEFAULT * Keep previous defaults (UNIX as shared and Windows as static) * Remove PROJ_LIBRARY_TYPE, since add_library() uses BUILD_SHARED_LIBS
2020-02-20CMake: rename ENABLE_LTO to ENABLE_IPOMike Taves
* Deprecate ENABLE_LTO, but still use it as an alias for now * Plan to remove ENABLE_LTO by PROJ 8.0 * Use CMake 3.9 logic to check feature and set property

CMake: simplify message functions
2020-02-11Use relative directory to locate PROJ resource files.Even Rouault
Fixes #1490 This is an extension of the Window-specific logic added recently to Unix builds. This reuses parts of proposed past commit https://github.com/OSGeo/PROJ/pull/1517/commits/82a07e51c6e24ddb936d131ababe29f1ac36ef14 (credits to @abellgithub)

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.

2019-02-11Make tmerc an alias for etmerc. (#1234)Kristian Evers
* Make tmerc an alias for etmerc This switches the algorithm used in tmerc to the Poder/Engsager tmerc algorithm. The original tmerc algorithm of Evenden/Snyder origin can still be accessed by adding the +approx flag when initializing a tmerc projection. The +approx flag can also be used when initializing UTM projections, in which case the Evenden/Snyder algorithm is used as well. If a tmerc projection is instantiated on a spherical earth the Evenden/Snyder algorithm is used as well since the Poder/Engsager algorithm is only defined on the ellipsoid. +proj=etmerc can still be instantiated for backwards compatibility reasons.

c6ab83f5742bc5ac6f9cb9a8b2a4f1ea241b6f63 already removed their availability in user facing application, but the library code remained, and appeared to be unused by the rest of the library, and not available to library users, the API being only in proj_internal.h. So remove all remains.

I've found that if building PROJ with lto, but GDAL without lto, exceptions thrown in PROJ are not properly captured by try {} blocks in PROJ C API, and unexpectedly go back up to GDAL. Might be a defect of the particular compiler I use (gcc 5.4 Ubuntu 16.04)
2018-11-14Implement RFC 2: Initial integration of "GDAL SRS barn" workEven Rouault
