Fixes #1867
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.

Add proj_create_derived_geographic_crs() and proj_create_conversion_pole_rotation_grib_convention() to address GRIB datasets using a pole rotation method
2019-11-25normalizeForVisualization() and other methods applying on a ProjectedCRS: do ↵Even Rouault
not mess the derivingConversion object of the original object (fixes #1736) normalizeForVisualization(), promoteTo3D(), demoteTo2D(), alterGeodeticCRS(), alterCSLinearUnit() and alterParametersLinearUnit() all used the object returned by derivingConversionRef() to create a new ProjectedCRS. While doing so, this caused the derivingConversion of the original object to have its targetCRS set to the object returned by normalizeForVisualization() and similar. If that object died, then the weak pointer would be reset, and the original ProjectedCRS() has now its derivingConversionRef()->targetCRS() nullptr So bottom line is use derivingConversion() for anything that is not pure reading !!! This is confirmed to be the fix for the QGIS scenario in https://github.com/qgis/QGIS/issues/30569#issuecomment-540060919 In QGIS use case, the issue arised when using a projected CRS with a non-GIS friendly axis (that is where normalizeForVisualization() created a new projectedCRS)

2019-11-17createOperations(): remove the concept of geodetic_datum_preferred_hubEven Rouault
This was introduced in 63857c92b271bbcd10df0a032304982011acb2a9. Due to the fix done in the previous commit, we can mostly revert the above commit. We just keep the added tests and the custom WGS 84<-->WGS 84 (Gxxxx) null transformations.

2019-09-26Improve vertical transformation supportEven Rouault
When we had a transformation between a compoundCRS and a target geographicCRS, we did not take into account that in the vertical->other_geog_CRS transformation we used, the other_geog_CRS was an implicit interpolation CRS. Thus before doing vertical adjustment, we must go to this interpolation CRS. The workflow is thus: source CRS -> interpolation CRS + vertical adjustment + interplation CRS -> target CRS
2019-09-12Coordinate transformation: improve transformations from/to WGS84 (Gxxxx)Even Rouault
Currently very few transformations from/to WGS84 (Gxxxx) are registered in the EPSG database, and there isn't even transformations between WGS84 EPSG:4326 and those ones. Consequently transformations to those realizations often ended up as no-operation, whereas going through WGS84 EPSG:4326 will bring more meaningful results. So register those EPSG:4326<-->WGS 84 (Gxxx) null transformations, and when having WGS 84 (Gxxx) as source/target, consider EPSG:4326 as an intermediate. This change has no effect on the existing direct transformations from/to WGS 84 (Gxxx).

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.

2019-03-29Add proj_normalize_for_visualization()Even Rouault
Fixes #1301 This function takes the output PJ from proj_create_crs_to_crs(), and add (or undo) the needed axis swap operations so that the object returned by proj_normalize_for_visualization() has the usual GIS axis order. In this implementation, this does something only if the coordinate system of the source or target CRS, geographic or projected, has NORTH, EAST ordering. CompoundCRS wrapping those objects are also handled.
