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.

2020-01-23Fix wrong use of derivingConversionRef() that caused GDAL bugEven Rouault
Hopefully final cut at solving the same class of bug that the one that affected QGIS in December. This time, this hit GDAL in the situation of https://lists.osgeo.org/pipermail/gdal-dev/2020-January/051500.html The bug fix for that particular issue is in PROJStringParser::createFromPROJString() But grepping more in the code base, I could find other potential smelly situations (might not be issues, but better be safe than sorry), so let's fix them too. Bottom line is: derivingConversionRef() should *only* be used for consultation, and never to create a new ProjectedCRS()
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.

2019-11-09Doc: document oddity related to identification of CRS from ESRI WKTEven Rouault
Or more generally formulations that don't have an explicit axis order. Refs https://github.com/pyproj4/pyproj/issues/475 projinfo 'GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]' returns EPSG:4326 with 100% confidence. But its axis order is not the same as EPSG:4326. I've pondered about this, like decreasing the confidence of the match, but this would have downstream effects on GDAL (shapefiles with the above content in a .prj would no longer be identified as EPSG:4326). So for now, document that oddity.

2019-10-30createFromWkt(): be tolerant to missing scale_factor parameter (fixes #1700)Even Rouault
This is invalid WKT, but GDAL 2.4 used to accept it and make a reasonable use of it... Currently we default it to 0 which is non sensical. Better use 1 as GDAL 2.4 did, and emit a warning. Other fix: proj_create_from_wkt() was documented to operate by default in non-strict validation mode, but it was actually in strict mode. So do as documented.
2019-10-24Generalize generalize_proj_crs_create_bound_vertical_crs_to_WGS84()Even Rouault
In recent commits, we added a generalize_proj_crs_create_bound_vertical_crs_to_WGS84() function, but there are situations where more accurate results can be obtained, if instead of specifying WGS84 as the hub CRS, the user can specify the exact hub CRS. For example the GEOID2018 grid is against NAD83(2011). So replace this function with proj_crs_create_bound_vertical_crs()

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.
