+nadgrids= and +pm= (#1998) Fixes issue reported at https://lists.osgeo.org/pipermail/gdal-dev/2020-February/051749.html The generated pipeline assumes that the input coordinates for the grid transformation were related to the non-Greenwich based datum, so we must compensate for that and add logic to go back to Greenwich.

2020-02-24createOperations(): keep height/z value in Helmert transform between 3D CRSEven Rouault
This is the consequence of a private email thread between me, Joel Haasdyk and Roger Lott. I initially raised that the GDA2020 technical manual advertized the Helmert transformation between GDA94 to GDA2020 to be a 3D one, with example of a test point where ellipsoidal heights where modified. It appears this was intended. The corresponding record in EPSG uses the EPSG:9607 "Coordinate Frame rotation (geog2D domain)" method between the 2D geographic CRS of GDA94 and GDA2020. From the email exchange, it appears that there's a lot of legacy explaining that Helmert transformations are registered only between 2D CRS, which doesn't mean that when applied to the corresponding 3D CRS, the change in ellipsoidal height should be discarded. Related to that, the EPSG database, while it has methods flagged "(geog3D domain)" never uses them. So... this changeset slightly ammends PROJ behaviour to ignore the "(geog2D domain)" flag, but only consider the dimensionality of the source & target CRS. However, for a EPSG transformation, those are always 2D CRS, hence introduce the use3DHelmert_ hack when we know that ultimately the 'real' source & target CRS are 3D. I wouldn't be surprised if in more complex pipeline the above logic would be lacking. But it fixes at least simple transformations.

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.
