Change Log

2.1.3

  • Added support for time transformations (issue #208)

  • Fixed projection equivalence testing for transformations (pull #231).

  • Switch to pytest for testing (pull #230)

  • Various testing fixes (pull #223, #222, #221, #220)

  • Convert PROJ error messages from bytes to strings (pull #219)

  • Fix data dir path separator to be (;) for windows and (:) for linux (pull #234)

2.1.2

  • Updated to use the CRS definition for Proj instances in transforms (issue #207)

  • Add option to skip tranformation operation if input and output projections are equivalent and always skip if the input and output projections are exact (issue #128)

  • Update setup.py method for checking PROJ version (pull #211)

  • Add internal proj error log messages to exceptions (pull #215)

2.1.1

  • Restore behavior of 1.9.6 when illegal projection transformation requested (return inf instead of raising an exception, issue #202). kwarg errcheck added to transform() and itransform() (default False). When errcheck=True an exception is raised.

2.1.0

  • Added Transformer to make repetitive transformations more efficient (issue #187)

  • Added fix for using local datumgrids with transform (issue #191)

  • Added from_pipeline() to support pipeline transformations.

  • Added fix for conversion between radians/degrees for transformations (issues #192 & #195)

2.0.2

  • add filter for boolean values in dict2string so “no_rot=True” works (issue #183).

  • make sure .pxd files included in source tarball.

  • add radians flag back in for transform/itransform (issue #185).

2.0.1

  • Ensure data path set properly for TransProj (pull request #179, addressed issue #176).

2.0.0

  • Update to PROJ.4 version 6.0.0 & removed support for older PROJ.4 versions.

  • Added pyproj.CRS class.

  • Updated pyproj.Proj & pyproj.transform to accept any input from CRS.from_user_input.

  • Removed internal PROJ.4 source code.

  • Changed default for preserve_units to be True in pyproj.Proj class initialization.

  • Modified logic for searching for the PROJ.4 data directory to not conflict with older versions of PROJ.4.

  • Added pyproject.toml.

1.9.6

  • fix segfault when inverse projection not defined (issue #43, pull request #44).

  • supports python 3.7

1.9.5.1

  • fix for issue #42 (compilation error with microsoft visual studio).

1.9.5

  • update proj4 source to latest github master (commit 953cc00fd87425395cabe37641cda905c4b587c1).

  • port of basemap fix for input arrays in fortran order

  • restore inverse Hammer patch that was lost when proj4 source code was updated.

1.9.4 (git tag v1.9.4rel)

  • migrate to github from googlecode.

  • update proj4 source code from svn r2595 (version 4.9.0RC2).

  • include runtime_library_dirs in setup-proj.py.

  • added to_latlong method (issue 51).

  • fix back azimuth when lon1 and lon2 are identical.

1.9.3 (svn revision 327)

  • Geod now uses C code adapted from geographiclib now included in proj4 source, instead of pure python code directly from geographiclib.

  • make radians=True work with Geod.npts (issue 47).

  • allow PROJ_DIR env var to control location of proj data (issue 40).

1.9.2 (svn revision 301)

  • updated proj4 src to 4.8.0 - includes two new map projections (natearth and isea).

1.9.1 (svn revision 285)

  • restore compatibility with python 2.4/2.5, which was broken by the addition of the geographiclib geodesic module (issue 36).

1.9.0 (svn revision 282)

  • use pure python geographiclib for geodesic computation codes instead of proj4.

  • don’t use global variable pj_errno for return codes, use pj_ctx_get_errno instead.

  • use new projCtx structure for thread safety in proj lib.

  • update C source and data from proj4 svn (r2140).

  • add pj_list and pj_ellps module level variables (a dict mapping short names to longer descriptions, e.g. pyproj.pj_list[‘aea’] = ‘Albers Equal Area’).

1.8.9 (svn revision 222)

  • Python 3 now supported.

  • allow ‘EPSG’ init (as well as ‘epsg’). This only worked on case-insensitive filesystems previously. Fixes issue 6.

  • added inverse to Hammer projection.

  • updated proj.4/src/pj_mutex.c from proj4 svn to fix a threading issue on windows (issue 25). Windows binary installers updated (version 1.8.8-1), courtesy Christoph Gohlke.

  • if inputs are NaNs, return huge number (1.e30).

1.8.8 (svn revision 196)

  • add extra datum shift files, added test/test_datum.py (fixes issue 22). datum shifts now work correctly in transform function.

1.8.7 (svn revision 175)

  • reverted pj_init.c to old version (from proj4 4.6.1) because version in 4.7.0 includes caching code that can cause segfaults in pyproj (issue 19).

  • added ‘preserve_units’ keyword to Proj.__init__ to suppress conversion to meters.

1.8.6 (svn revision 169)

  • now works with ms vs2008, vs2003 (fixed missing isnan).

  • updated to proj 4.7.0 (fixes a problem coexisting with pyqt).

  • allow Geod instance to be initialized using a proj4 string

1.8.5 (svn revision 155)

  • allow Proj instance to be initialized using a proj4 string (instead of just a dict or kwargs).

1.8.4 (svn revision 151)

  • updated proj4 sources to version 4.6.0

1.8.3 (svn revision 146)

  • fixed bug in Geod class that caused erroneous error message “undefined inverse geodesic (may be an antipodal point)”.

  • fix __reduce__ method of Geod class so instances can be pickled.

  • make sure points outside projection limb are set to 1.e30 on inverse transform (if errcheck=False).

  • fixed small setup.py bug.

  • generate C source with Cython 0.9.6.6 (pycompat.h no longer needed).

1.8.2

  • added ‘srs’ (spatial reference system) instance variable to Proj.

  • instead of returning HUGE_VAL (usually ‘inf’) when projection not defined and errcheck=False, return 1.e30.

  • added Geod class for geodesic (i.e. Great Circle) computations. Includes doctests (which can be run with pyproj.test()).

  • proj.4 source code now included, thus removing proj.4 lib dependency. Version 4.5.0 is included, with a patch to create an API for geodesic computations.

  • python 2.4 compatibility patch (suggested by Andrew Straw) from M. v. Loewis: http://mail.python.org/pipermail/python-dev/2006-March/062561.html

1.8.1

  • if given tuples, returns tuples (instead of lists).

  • test for numpy arrays first.

  • Fixed error in docstring example.

  • README.html contains html docstrings generated by pydoc.

  • Renamed pyproj.so to _pyproj.so, created a new python module called pyproj.py. Moved as code as possible from _pyproj.so to pyproj.py.

  • docstring examples now executed by doctest when ‘pyproj.test()’ is run.

  • added test to _pyproj.c which defines Py_ssize_t for python < 2.5. This is necessary when pyrex 0.9.5 is used.

1.8.0

  • Better error handling Proj.__init__.

  • Added optional keyword ‘errcheck’ to __call__ method.

  • If True, an exception is raised if the transformation is invalid.

1.7.3

  • python 2.5 support.
