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.

2020-01-22Merge 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.
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.

2019-03-29Add proj_normalize_for_visualization()Even Rouault
Fixes #1301 This function takes the output PJ from proj_create_crs_to_crs(), and add (or undo) the needed axis swap operations so that the object returned by proj_normalize_for_visualization() has the usual GIS axis order. In this implementation, this does something only if the coordinate system of the source or target CRS, geographic or projected, has NORTH, EAST ordering. CompoundCRS wrapping those objects are also handled.

2019-02-07Add proj_get_crs_info_list_from_database()Even Rouault
This method is intended to be used typically by GUI that lists all possible CRS. What is does could be done by previously existing functions, but it is much faster. It typically runs in less than 0.1s (hot run) versus ~0.5s with the method that consists in enumerating all codes and instanciating a PJ object for each of them.

2019-01-01Split ISO19111 C API docs into functions and typesKristian Evers
The rest of the C API is structured such that type definitions goes into one page and functions to another. This commit makes sure the same is done for the C bindings to the ISO19111 C++ API by defining two doxygen groups in proj.h, which is then organized into the proper pages with Sphinx and breathe.
