u'''A pure Python implementation of geodesy tools for various ellipsoidal
and spherical earth models using precision trigonometric, vector-based,
elliptic and approximate methods for geodetic (lat-/longitude) and
geocentric (U{ECEF<https://WikiPedia.org/wiki/ECEF>} cartesian) coordinates.

Transcribed from U{JavaScript originals<https://GitHub.com/ChrisVeness/geodesy>}
by I{Chris Veness (C) 2005-2019} and several U{C++ classes
<https://GeographicLib.SourceForge.io/html/annotated.html>} by I{Charles F.F.
Karney (C) 2008-2020} and published under the same U{MIT License
<https://OpenSource.org/licenses/MIT>}**.

There are three modules for ellipsoidal earth models, C{ellipsoidalKarney},
C{-Vincenty} and C{-Nvector} and two for spherical ones, C{sphericalTrigonometry}
and C{-Nvector}.  Each module provides a geodetic B{C{LatLon}} and a geocentric
B{C{Cartesian}} class with methods and functions to compute distance, area,
perimeter, initial and final bearing, intermediate and nearest points,
intersections of circles, path intersections, conversions and unrolling, among
other things.  For more information and further details see the U{documentation
<https://mrJean1.GitHub.io/PyGeodesy>}, the descriptions of U{Latitude/Longitude
<https://www.Movable-Type.co.UK/scripts/latlong.html>}, U{Vincenty
<https://www.Movable-Type.co.UK/scripts/latlong-vincenty.html>} and U{Vector-based
<https://www.Movable-Type.co.UK/scripts/latlong-vectors.html>} geodesy, the original
U{JavaScript source<https://GitHub.com/ChrisVeness/geodesy>} or U{docs
<https://www.Movable-Type.co.UK/scripts/geodesy/docs>} and the Python
U{geographiclib<https://PyPI.org/project/geographiclib>}.

Also included are modules for conversions to and from U{Cassini-Soldner
<https://GeographicLib.SourceForge.io/html/classGeographicLib_1_1CassiniSoldner.html>},
U{ECEF<https://WikiPedia.org/wiki/ECEF>} (Earth-Centered, Earth-Fixed cartesian),

and Universal Transverse Mercator) and U{Web Mercator

(British Ordinance Survery Grid Reference) grid references, U{TRF
<http://ITRF.ENSG.IGN.FR>} (Terrestrial Reference Frames) and modules
to encode and decode U{EPSG<https://www.EPSG-Registry.org>}, U{Geohashes
<https://www.Movable-Type.co.UK/scripts/geohash.html>}, U{Georefs (WGRS)
<https://WikiPedia.org/wiki/World_Geographic_Reference_System>} and
U{Garefs (GARS)<https://WikiPedia.org/wiki/Global_Area_Reference_System>}.

Other modules provide U{Albers Equal-Area
<https://GeographicLib.SourceForge.io/html/classGeographicLib_1_1AlbersEqualArea.html>}
projections, azimuthal projections and Lambert conformal conic projections and
positions (from U{John P. Snyder, "Map Projections -- A Working Manual", 1987
<https://pubs.er.USGS.gov/djvu/PP/PP_1395.pdf>}), functions to clip a path or polygon
of C{LatLon} points using the U{Cohen–Sutherland
<https://WikiPedia.org/wiki/Cohen-Sutherland_algorithm>} and the U{Sutherland-Hodgman
<https://WikiPedia.org/wiki/Sutherland-Hodgman_algorithm>} methods, functions to
U{simplify<https://Bost.Ocks.org/mike/simplify>} or linearize a path of C{tLon}
points (or a U{NumPy array
<https://docs.SciPy.org/doc/numpy/reference/generated/numpy.array.html>}),
including implementations of the U{Ramer-Douglas-Peucker
<https://WikiPedia.org/wiki/Ramer-Douglas-Peucker_algorithm>} the
U{Visvalingam-Whyatt<https://hydra.Hull.ac.UK/resources/hull:8338>} and
U{Reumann-Witkam<https://psimpl.SourceForge.net/reumann-witkam.html>}
the algorithms and modified versions of the former.  Other classes
U{interpolate<https://docs.SciPy.org/doc/scipy/reference/interpolate.html>}
the height of C{LatLon} points and several C{Geoid} models or compute
various U{Fréchet<https://WikiPedia.org/wiki/Frechet_distance>} or
U{Hausdorff<https://WikiPedia.org/wiki/Hausdorff_distance>} distances.

Installation
============

To install PyGeodesy, type C{pip install PyGeodesy} or C{easy_install
PyGeodesy} in a terminal or command window.

Alternatively, download C{PyGeodesy-yy.m.d.zip} from U{PyPI
<https://PyPI.org/project/PyGeodesy>} or U{GitHub
<https://GitHub.com/mrJean1/PyGeodesy>}, C{unzip} the downloaded file,
C{cd} to directory C{Pygeodesy-yy.m.d} and type C{python setup.py
install}.  To run all PyGeodesy tests, type C{python setup.py test}
before or after installation.

Installation of U{geographiclib<https://PyPI.org/project/geographiclib>},
U{numpy<https://PyPI.org/project/numpy>} and U{scipy
<https://PyPI.org/project/scipy>} is optional.  However, the former is
required to use classes L{EquidistantKarney}, L{GnomonicKarney},
L{CassiniSoldner} and L{Css} and function L{toCss}, for module
L{ellipsoidalKarney} classes C{LatLon} and C{Cartesian} and functions
C{areaOf}, C{intersections2} and C{perimeterOf} and for the
L{HeightIDWkarney} interpolator.  Both the latter are needed for the
C{Geoid...} and C{Height...} interpolator classes, except the
L{GeoidKarney} and all C{HeightIDW...} classes.

Documentation
=============

In addition to the C{pygeodesy} package, the U{PyGeodesy
<https://PyPI.org/project/PyGeodesy>} U{distribution files
<https://GitHub.com/mrJean1/PyGeodesy/tree/master/dist>} contain the
tests, the test results (on macOS only) and the complete U{documentation
<https://mrJean1.GitHub.io/PyGeodesy>} (generated by U{Epydoc
<https://PyPI.org/project/epydoc>} using command line: C{epydoc --html
--no-private --no-source --name=PyGeodesy --url=... -v pygeodesy}).

Classes with a name ending in C{-Karney} and several more are transcribed from
I{Karney}'s U{C++ classes<https://GeographicLib.SourceForge.io/html/annotated.html>}
or require I{Karney}'s U{geographiclib<https://PyPI.org/project/geographiclib>}
package to be installed.  A complete list is in module U{karney

Some function and method names differ from the JavaScript version. In such
cases documentation tag B{JS name:} shows the original JavaScript name.
