2022-03-11unitconvert: round to nearest date when converting to yyyymmdd.Brendan Jurd
This resolves an issue where converting from a low-precision decimalyear to yyyymmdd gave the wrong result, due to mjd_to_yyyymmdd() truncating away the fractional time component. This commit changes the behaviour of mjd_to_yyyymmdd() to round to the nearest date, instead of truncating. Refs #1483

2021-09-30proj_factors(): accept P to be a projected CRS (fixes #2854)Even Rouault
Updated doc: Starting with PROJ 8.2, the P object can be a projected CRS, for example instantiated from a EPSG CRS code. The factors computed will be those of the map projection implied by the transformation from the base geographic CRS of the projected CRS to the projected CRS. The input geodetic coordinate lp should be such that lp.lam is the longitude in radian, and lp.phi the latitude in radian (thus independently of the definition of the base CRS, if P is a projected CRS).

2021-08-15Add support for Degree Sign on input (#2791)Brendan Jurd
This commit adds support in dsmtor() for a Degree Sign (U+00B0), encoded as UTF-8 (`\xc2\xb0`) or as a single byte (`\xb0`) (in ISO 8859 parts 1-4, 7-10, 13, 15, 16, and several Windows code pages), as an alternative symbol to `D`/`d` to designate the degree unit. Fixes #2712.

PROJ_SPATIAL_CRITERION_PARTIAL_INTERSECTION if area is specified" This reverts commit ebe3425bf66287e004958eb53976d3837f88b9e1. It was found to break gdalwarp usage in https://github.com/OSGeo/gdal/issues/3695 when passing a bbox that is quite large.

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.

#1329) In case several coordinate operations are returned for a CRS to CRS transformation, we currently determine the one to use by selecting the first operation whose bounding box contains the input point. This commit adds a fallback case where after doing that first iteration and finding no appropriate candidate, we try again by selecting the first operation available that does not involve grid based transformations.
