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

2020-04-04hgridshift/vgridshift: defer grid opening when grid has already been openedEven Rouault
Relates to #2115 With the fix of https://github.com/OSGeo/PROJ/pull/2128, transforming between EPSG:4326+3855 and EPSG:4269+5703 leads to many operations with many grids, and opening a file handle for each operation saturates the limit of 1024 file handles opened simunalteously. This fix defers grid opening when a transformation has already been instanciated with the same grid.

2020-03-13Add proj_get_suggested_operation()Even Rouault
Return the index of the operation that would be the most appropriate to transform the specified coordinates. This operation may use resources that are not locally available, depending on the search criteria used by proj_create_operations(). This could be done by using proj_create_operations() with a punctual bounding box, but this function is faster when one needs to evaluate on many points with the same (source_crs, target_crs) tuple.
2020-03-11pj_phi2(): speed-up computation (and thus inverse ellipsoidal Mercator and LCC)Even Rouault
This does not change the numeric values returned by the method, as far as I could see on a few samplings. The tricks used save a call to sin() and atan() at each iteration. This directly affects speed of inverse Mercator and LCC (among others), in their ellipsoidal formulation. Timings on inverse Mercator show a 31% speed-up at mid-latitudes where pj_phi2() needs 5 iterations, and 24% at latitudes close to 0 or 90deg where it needs one iteration.

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.

2019-09-05PROJStringParser::createFromPROJString(): avoid potential infinite recursion ↵Even Rouault
(fixes #1574) The exact circumstances are a bit difficult to explain, but they involve using a non-default context, enabling proj_context_use_proj4_init_rules() on it, using proj_create(ctxt, "+init=epsg:XXXX +type=crs"), whereas PROJ_LIB is defined to a directory that has a 'epsg' file in it.

Clean up time handling in helmert and deformation
2019-02-14deformation: Replace +t_obs with +dtKristian Evers
The +t_obs parameter was confusing for users since it effectively overwrote the observation time in input coordinates. To make it more clear what is the operation is doing, users are now required to directly specify the time span for which they wish to apply a given deformation. The parameter +dt has been added for that purpose. The new parameter is mutually exclusive with +t_epoch. +dt is used when deformation for a set amount of time is needed and +t_epoch is used (in conjunction with the observation time of the input coordinate) when deformation from a specific epoch to the observation time is needed.
2019-02-13Add push and pop operationsKristian Evers
This commit introduces the concept of a pipeline coordinate stack in which components of coordinates can be saved and loaded from. This makes it possible to moved values from one step of a pipeline to another, effectively overwriting parts of the output from a given step.
