Fixes #1846
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.

2019-12-09isea docs: Rewrite intro and reference to reflect actual projectionKristian Evers
Previous version was describing oea by mistake. It is also a projection by Snyder and the isea docs was based on the paper on the oea projection. This commit fixes that.
