        Manipulation and analysis of geometric objects in the Cartesian plane.
        
        Shapely is a BSD-licensed Python package for manipulation and analysis of
        planar geometric objects. It is based on the widely deployed `GEOS
        <http://trac.osgeo.org/geos/>`__ (the engine of `PostGIS
        <http://postgis.org>`__) and `JTS
        <http://www.vividsolutions.com/jts/jtshome.htm>`__ (from which GEOS is ported)
        libraries. Shapely is not concerned with data formats or coordinate systems,
        but can be readily integrated with packages that are. For more details, see:
        
        * `Shapely GitHub repository <https://github.com/Toblerity/Shapely>`__
        * `Shapely documentation and manual <https://shapely.readthedocs.io/en/latest/>`__
        
        Requirements
        ============
        
        Shapely 1.6 requires
        
        * Python >=2.6 (including Python 3.x)
        * GEOS >=3.3 
        
        Installing Shapely 1.6
        ======================
        
        Shapely may be installed from a source distribution or one of several kinds
        of built distribution.
        
        Built distributions
        -------------------
        
        Windows users have two good installation options: the wheels at
        http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely and the 
        Anaconda platform's [conda-forge](https://conda-forge.github.io/)
        channel.
        
        OS X and Linux users can get Shapely wheels with GEOS included from the 
        Python Package Index with a recent version of pip (8+):
        
        .. code-block:: console
        
            $ pip install shapely
        
        A few extra speedups that require Numpy can be had by running
        
        .. code-block:: console
        
            $ pip install shapely[vectorized]
        
        Shapely is available via system package management tools like apt, yum, and
        Homebrew, and is also provided by popular Python distributions like Canopy and
        Anaconda.
        
        Source distributions
        --------------------
        
        If you want to build Shapely from source for compatibility with
        other modules that depend on GEOS (such as cartopy or osgeo.ogr) or want to
        use a different version of GEOS than the one included in the project wheels
        you should first install the GEOS library, Cython, and Numpy on your system
        (using apt, yum, brew, or other means) and then direct pip to ignore the binary
        wheels.
        
        .. code-block:: console
        
            $ pip install shapely --no-binary shapely
        
        If you've installed GEOS to a standard location, the geos-config program
        will be used to get compiler and linker options. If geos-config is not on
        your executable, it can be specified with a GEOS_CONFIG environment
        variable, e.g.:
        
        .. code-block:: console
        
            $ GEOS_CONFIG=/path/to/geos-config pip install shapely
        
        Usage
        =====
        
        Here is the canonical example of building an approximately circular patch by
        buffering a point.
        
        .. code-block:: pycon
        
            >>> from shapely.geometry import Point
            >>> patch = Point(0.0, 0.0).buffer(10.0)
            >>> patch
            <shapely.geometry.polygon.Polygon object at 0x...>
            >>> patch.area
            313.65484905459385
        
        See the manual for comprehensive usage snippets and the dissolve.py and
        intersect.py examples.
        
        Integration
        ===========
        
        Shapely does not read or write data files, but it can serialize and deserialize
        using several well known formats and protocols. The shapely.wkb and shapely.wkt
        modules provide dumpers and loaders inspired by Python's pickle module.
        
        .. code-block:: pycon
        
            >>> from shapely.wkt import dumps, loads
            >>> dumps(loads('POINT (0 0)'))
            'POINT (0.0000000000000000 0.0000000000000000)'
        
        Shapely can also integrate with other Python GIS packages using GeoJSON-like
        dicts.
        
        .. code-block:: pycon
        
            >>> import json
            >>> from shapely.geometry import mapping, shape
            >>> s = shape(json.loads('{"type": "Point", "coordinates": [0.0, 0.0]}'))
            >>> s
            <shapely.geometry.point.Point object at 0x...>
            >>> print(json.dumps(mapping(s)))
            {"type": "Point", "coordinates": [0.0, 0.0]}
        
        Development and Testing
        =======================
        
        Dependencies for developing Shapely are listed in requirements-dev.txt. Cython
        and Numpy are not required for production installations, only for development.
        Use of a virtual environment is strongly recommended.
        
        .. code-block:: console
        
            $ virtualenv .
            $ source bin/activate
            (env)$ pip install -r requirements-dev.txt
            (env)$ pip install -e .
        
        We use py.test to run Shapely's suite of unittests and doctests.
        
        .. code-block:: console
        
            (env)$ python -m pytest

        Changes
        =======
        
        1.6.4 (2017-01-24)
        ------------------
        
        - Handle a ``TypeError`` that can occur when geometries are torn down (#473,
          #528).
        
        - 
        1.6.3 (2017-12-09)
        ------------------
        
        - AttributeError is no longer raised when accessing __geo_interface__ of an
          empty polygon (#450).
        - ``asShape`` now handles empty coordinates in mappings as ``shape`` does
          (#542). Please note that ``asShape`` is likely to be deprecated in a future
          version of Shapely.
        - Check for length of LineString coordinates in speed mode, preventing crashes
          when using LineStrings with only one coordinate (#546).
        
        1.6.2 (2017-10-30)
        ------------------
        
        - A 1.6.2.post1 release has been made to fix a problem with macosx wheels
          uploaded to PyPI.
        
        1.6.2 (2017-10-26)
        ------------------
        
        - Splitting a linestring by one of its end points will now succeed instead of
          failing with a ``ValueError`` (#524, #533).
        - Missing documentation of a geometry's ``overlaps`` predicate has been added
          (#522).
        
        1.6.1 (2017-09-01)
        ------------------
        
        - Avoid ``STRTree`` crashes due to dangling references (#505) by maintaining
          references to added geometries.
        - Reduce log level to debug when reporting on calls to ctypes ``CDLL()`` that
          don't succeed and are retried (#515).
        - Clarification: applications like GeoPandas that need an empty geometry object
          should use ``BaseGeometry()`` instead of ``Point()`` or ``Polygon()``. An
          ``EmptyGeometry`` class has been added in the master development branch and
          will be available in the next non-bugfix release.
        
        1.6.0 (2017-08-21)
        ------------------
        
        Shapely 1.6.0 adds new attributes to existing geometry classes and new
        functions (``split()`` and ``polylabel()``) to the shapely.ops module.
        Exceptions are consolidated in a shapely.errors module and logging practices
        have been improved. Shapely's optional features depending on Numpy are now
        gathered into a requirements set named "vectorized" and these may be installed
        like ``pip install shapely[vectorized]``.
        
        Much of the work on 1.6.0 was aimed to improve the project's build and
        packaging scripts and to minimize run-time dependencies. Shapely now vendorizes
        packaging to use during builds only and never again invokes the geos-config
        utility at run-time.
        
        In addition to the changes listed under the alpha and beta pre-releases below,
        the following change has been made to the project:
        
        - Project documentation is now hosted at 
          https://shapely.readthedocs.io/en/latest/.
        
        Thank you all for using, promoting, and contributing to the Shapely project.
        
        1.6b5 (2017-08-18)
        ------------------
        
        Bug fixes:
        
        - Passing a single coordinate to ``LineString()`` with speedups disabled now
          raises a ValueError as happens with speedups enabled. This resolves #509.
        
        1.6b4 (2017-02-15)
        ------------------
        
        Bug fixes:
        
        - Isolate vendorized packaging in a _vendor directory, remove obsolete
          dist-info, and remove packaging from project requirements (resolves #468).
        
        1.6b3 (2016-12-31)
        ------------------
        
        Bug fixes:
        
        - Level for log messages originating from the GEOS notice handler reduced from
          WARNING to INFO (#447).
        - Permit speedups to be imported again without Numpy (#444).
        
        1.6b2 (2016-12-12)
        ------------------
        
        New features:
        
        - Add support for GeometryCollection to shape and asShape functions (#422).
        
        1.6b1 (2016-12-12)
        ------------------
        
        Bug fixes:
        
        - Implemented __array_interface__ for empty Points and LineStrings (#403).
        
        1.6a3 (2016-12-01)
        ------------------
        
        Bug fixes:
        
        - Remove accidental hard requirement of Numpy (#431).
        
        Packaging:
        
        - Put Numpy in an optional requirement set named "vectorized" (#431).
        
        1.6a2 (2016-11-09)
        ------------------
        
        Bug fixes:
        
        - Shapely no longer configures logging in ``geos.py`` (#415).
        
        Refactoring:
        
        - Consolidation of exceptions in ``shapely.errors``.
        - ``UnsupportedGEOSVersionError`` is raised when GEOS < 3.3.0 (#407).
        
        Packaging:
        
        - Added new library search paths to assist Anaconda (#413).
        - geos-config will now be bypassed when NO_GEOS_CONFIG env var is set. This
          allows configuration of Shapely builds on Linux systems that for whatever
          reasons do not include the geos-config program (#322).
        
        1.6a1 (2016-09-14)
        ------------------
        
        New features:
        
        - A new error derived from NotImplementedError, with a more useful message, is
          raised when the GEOS backend doesn't support a called method (#216).
        - The ``project()`` method of LineString has been extended to LinearRing
          geometries (#286).
        - A new ``minimum_rotated_rectangle`` attribute has been added to the base
          geometry class (#354).
        - A new ``shapely.ops.polylabel()`` function has been added. It
          computes a point suited for labeling concave polygons (#395).
        - A new ``shapely.ops.split()`` function has been added. It splits a
          geometry by another geometry of lesser dimension: polygon by line, line by
          point (#293, #371).
        - ``Polygon.from_bounds()`` constructs a Polygon from bounding coordinates
          (#392).
        - Support for testing with Numpy 1.4.1 has been added (#301).
        - Support creating all kinds of empty geometries from empty lists of Python
          objects (#397, #404).
        
        Refactoring:
        
        - Switch from ``SingleSidedBuffer()`` to ``OffsetCurve()`` for GEOS >= 3.3
          (#270).
        - Cython speedups are now enabled by default (#252).
        
        Packaging:
        
        - Packaging 16.7, a setup dependency, is vendorized (#314).
        - Infrastructure for building manylinux1 wheels has been added (#391).
        - The system's ``geos-config`` program is now only checked when ``setup.py``
          is executed, never during normal use of the module (#244).
        - Added new library search paths to assist PyInstaller (#382) and Windows
          (#343).
        
        1.5.17 (2016-08-31)
        -------------------
        - Bug fix: eliminate memory leak in geom_factory() (#408).
        - Bug fix: remove mention of negative distances in parallel_offset and note
          that vertices of right hand offset lines are reversed (#284).
        
        1.5.16 (2016-05-26)
        -------------------
        - Bug fix: eliminate memory leak when unpickling geometry objects (#384, #385).
        - Bug fix: prevent crashes when attempting to pickle a prepared geometry,
          raising ``PicklingError`` instead (#386).
        - Packaging: extension modules in the OS X wheels uploaded to PyPI link only
          libgeos_c.dylib now (you can verify and compare to previous releases with
          ``otool -L shapely/vectorized/_vectorized.so``).
        
        1.5.15 (2016-03-29)
        -------------------
        - Bug fix: use uintptr_t to store pointers instead of long in _geos.pxi,
          preventing an overflow error (#372, #373). Note that this bug fix was
          erroneously reported to have been made in 1.5.14, but was not.
        
        1.5.14 (2016-03-27)
        -------------------
        - Bug fix: use ``type()`` instead of ``isinstance()`` when evaluating geometry
          equality, preventing instances of base and derived classes from 
          being mistaken for equals (#317).
        - Bug fix: ensure that empty geometries are created when constructors have no
          args (#332, #333).
        - Bug fix: support app "freezing" better on Windows by not relying on the
          ``__file__`` attribute (#342, #377).
        - Bug fix: ensure that empty polygons evaluate to be ``==`` (#355).
        - Bug fix: filter out empty geometries that can cause segfaults when creating
