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)¶

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).
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
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.
Better error handling Proj.__init__.
Added optional keyword ‘errcheck’ to __call__ method.
If True, an exception is raised if the transformation is invalid.
python 2.5 support.
