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.

2020-03-11Doc: use 'ellipsoidal' to refer to the ellipsoidal formulation (to be ↵Even Rouault
opposed to the spherical one) Instead of 'elliptical'. Was suggested by @cffk in https://github.com/OSGeo/PROJ/pull/2030#issuecomment-596132341 An elliptical projection is a projection whose global shape fits inside an ellipsoid, like Mollweide. At least according to https://www.merriam-webster.com/dictionary/elliptical%20projection and https://en.wikipedia.org/wiki/Mollweide_projection
2020-03-10utm/ups: make sure to set errno to PJD_ERR_ELLIPSOID_USE_REQUIRED if es==0Even Rouault
ENOMEM was wrongly set after setting PJD_ERR_ELLIPSOID_USE_REQUIRED Note: it is a bit strange to forbid the pure spherical case whereas the maths would allow it. I presume this is due to the typical usage of those methods.

2020-03-05Remove occurences of deprecated PROJ.4 syntaxKristian Evers
+no_defs and +datum has no effect on the behaviour of proj, so can be left out in these examples in the docs. +no_defs in rare occasions would have had an effect in older PROJ versions but not from PROJ 6 and onwards. +datum has ever only been honoured by cs2cs and pj_transform(). Fixes #2017

2020-01-25Fix ingestion of +proj=cea with +k_0Even Rouault
Fixes #1881 Digging into the implementation of proj=cea, it appears that k_0 and lat_ts are intended to be exclusive ways of specifying the same concept. EPSG only models the variant using lat_s. So if k_0 is found and lat_ts is absent, compute the equivalent value of lat_ts from k_0. Note: k_0 should normally be in the [0,1] range. In case creative users would use something outside, we raise an exception, even if the cea implementation could potentially deal with any k_0 value. Hopefully this is a (reasonable) limitation that will address nominal use cases.

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.
