2020-04-15tmerc/utm: add a +algo=auto/evenden_snyder/poder_engsager parameterEven Rouault
The default remains +alg=poder_engsager. This default value can be changed in proj.ini +algo=auto will use Evenden Synder implementation if the error in doing so remains below 0.1 mm on Earth-sized ellipsoid
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

2020-03-11Doc: 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.
