A pure Python implementation of geodesy tools for various ellipsoidal and spherical earth models using precision trigonometric, vector-based and approximate methods for geodetic (lat-/longitude) and geocentric cartesian (x/y/z) coordinates.
Also included are modules for conversions to and from UTM (Universal Transverse Mercator) and Web Mercator (Pseudo-Mercator) coordinates, MGRS (NATO Military Grid Reference System) and OSGR (British Ordinance Survery Grid Reference) grid references and a module for encoding and decoding Geohashes.
Two other modules provide Lambert conformal conic projections and positions (from John P. Snyder, Map Projections -- A Working Manual, 1987, pp 107-109) and several functions to simplify or linearize a path of LatLon points (or a NumPy array), including implementations of the Ramer-Douglas-Peucker, the Visvalingam-Whyatt and the Reumann-Witkam algorithms and modified versions of the former.
All Python source code has been statically checked with PyChecker, PyFlakes, PyCodeStyle (formerly Pep8) and McCabe using Python 2.7.15 and with Flake8 using Python 3.7.0, both in 64-bit on macOS 10.13.6 High Sierra.
The tests have been run with Python 2.7.15 (with geographiclib 1.49 and numpy 1.14.0), with Python 3.7.0 (with geographiclib 1.49) and with PyPy 6.0.0 (Python 2.7.13 and 3.5.3) on macOS 10.13.6 High Sierra and macOS 10.14 Mojave, with Python 2.6.9, 2.7.14, 3.5.6 and 3.6.3 (and geographiclib 1.49) on Debian 8 and with Python 3.7.0 (and geographiclib 1.49) on Debian 9, all in 64-bit only and with Python 2.7.15, 3.6.6 and 3.7.0 (all with geographiclib 1.49) on Windows Server 2012R2 in 32- and 64-bit.
Previously, the tests were run with Python 2.6.9 (and numpy 1.6.2), 2.7.10 (and numpy 1.8.0rc1), 2.7.13, 2.7.14 (and numpy 1.13.1), 3.5.3, 3.6.2, 3.6.3, 3.6.4, 3.6.5 and Intel-Python 3.5.3 (and numpy 1.11.3) on MacOS X 10.10 Yosemite, MacOS X 10.11 El Capitan, macOS 10.12 Sierra, macOS 10.13.4 and/or 10.13.5 High Sierra, with Pythonista 3.1 on iOS 10.3.3, 11.0.3, 11.1.2 and 11.3 on iPad4, with Pythonista 3.2 on iOS 11.4.1 and 12.0 on iPad4, iPhone7 and/or iPhone10, all in 64-bit only and with 32-bit Python 2.6.6 on Windows XP SP3 and with 32-bit Python 2.7.14 on Windows 10 Pro.
In addition to the PyGeodesy package, the distribution files contain the
tests, the test results (on macOS only) and the complete documentation
generated by Epydoc using command line:
epydoc --html --no-private
--no-source --name=PyGeodesy --url=... -v pygeodesy.
To install PyGeodesy, type
pip install PyGeodesy or
PyGeodesy in a terminal or command window. Alternatively, download
PyGeodesy-yy.m.d from PyPI or GitHub,
unzip the downloaded file,
cd to directory
PyGeodesy-yy.m.d and type
python setup.py install.
To run all PyGeodesy tests, type
python setup.py test before installation.
