        Fiona is designed to be simple and dependable. It focuses on reading and
        writing data in standard Python IO style and relies upon familiar Python types
        and protocols such as files, dictionaries, mappings, and iterators instead of
        classes specific to OGR. Fiona can read and write real-world data using
        multi-layered GIS formats and zipped virtual file systems and integrates
        readily with other Python GIS packages such as pyproj_, Rtree_, and Shapely_.

        Usage
        =====
        
        Collections
        -----------
        
        Records are read from and written to ``file``-like `Collection` objects
        returned from the ``fiona.open()`` function.  Records are mappings modeled on
        the GeoJSON format. They don't have any spatial methods of their own, so if you
        want to do anything fancy with them you will probably need Shapely or something
        like it. Here is an example of using Fiona to read some records from one data
        file, change their geometry attributes, and write them to a new data file.
        
        .. code-block:: python
        
            import fiona
          
            # Register format drivers with a context manager
            
            with fiona.drivers():
        
                # Open a file for reading. We'll call this the "source."
                
                with fiona.open('tests/data/coutwildrnp.shp') as source:
        
                    # The file we'll write to, the "sink", must be initialized
                    # with a coordinate system, a format driver name, and
                    # a record schema.  We can get initial values from the open
                    # collection's ``meta`` property and then modify them as
                    # desired.
        
                    meta = source.meta
                    meta['schema']['geometry'] = 'Point'
        
                    # Open an output file, using the same format driver and
                    # coordinate reference system as the source. The ``meta``
                    # mapping fills in the keyword parameters of fiona.open().
                    
                    with fiona.open('test_write.shp', 'w', **meta) as sink:
        
                        # Process only the records intersecting a box.
                        for f in source.filter(bbox=(-107.0, 37.0, -105.0, 39.0)):
                  
                            # Get a point on the boundary of the record's
                            # geometry.
                            
                            f['geometry'] = {
                                'type': 'Point',
                                'coordinates': f['geometry']['coordinates'][0][0]}
                      
                            # Write the record out.
                            
                            sink.write(f)
                      
                # The sink's contents are flushed to disk and the file is
                # closed when its ``with`` block ends. This effectively
                # executes ``sink.flush(); sink.close()``.
        
            # At the end of the ``with fiona.drivers()`` block, context
            # manager exits and all drivers are de-registered.
        
        The fiona.drivers() function and context manager are new in 1.1. The
        example above shows the way to use it to register and de-register
        drivers in a deterministic and efficient way. Code written for Fiona 1.0
        will continue to work: opened collections may manage the global driver
        registry if no other manager is present.
        
        Reading Multilayer data
        -----------------------
        
        Collections can also be made from single layers within multilayer files or
        directories of data. The target layer is specified by name or by its integer
        index within the file or directory. The ``fiona.listlayers()`` function
        provides an index ordered list of layer names.
        
        .. code-block:: python
        
            with fiona.drivers():
        
                for layername in fiona.listlayers('tests/data'):
                    with fiona.open('tests/data', layer=layername) as src:
                        print(layername, len(src))
            
            # Output:
            # (u'coutwildrnp', 67)
        
        Layer can also be specified by index. In this case, ``layer=0`` and
        ``layer='test_uk'`` specify the same layer in the data file or directory.
        
        .. code-block:: python
        
            with fiona.drivers():
        
                for i, layername in enumerate(fiona.listlayers('tests/data')):
                    with fiona.open('tests/data', layer=i) as src:
                        print(i, layername, len(src))
            
            # Output:
            # (0, u'coutwildrnp', 67)
        
        Writing Multilayer data
        -----------------------
        
        Multilayer data can be written as well. Layers must be specified by name when
        writing.
        
        .. code-block:: python
            
            with fiona.drivers():
        
                with open('tests/data/cowildrnp.shp') as src:
                    meta = src.meta
                    f = next(src)
            
                with fiona.open('/tmp/foo', 'w', layer='bar', **meta) as dst:
                    dst.write(f)
            
                print(fiona.listlayers('/tmp/foo'))
        
                with fiona.open('/tmp/foo', layer='bar') as src:
                    print(len(src))
                    f = next(src)
                    print(f['geometry']['type'])
                    print(f['properties'])
            
                # Output:
                # [u'bar']
                # 1
                # Polygon
                # OrderedDict([(u'PERIMETER', 1.22107), (u'FEATURE2', None), (u'NAME', u'Mount Naomi Wilderness'), (u'FEATURE1', u'Wilderness'), (u'URL', u'http://www.wilderness.net/index.cfm?fuse=NWPS&sec=wildView&wname=Mount%20Naomi'), (u'AGBUR', u'FS'), (u'AREA', 0.0179264), (u'STATE_FIPS', u'49'), (u'WILDRNP020', 332), (u'STATE', u'UT')])
        
        A view of the /tmp/foo directory will confirm the creation of the new files.
        
        .. code-block:: console
        
            $ ls /tmp/foo
            bar.cpg bar.dbf bar.prj bar.shp bar.shx
        
        Collections from archives and virtual file systems
        --------------------------------------------------
        
        Zip and Tar archives can be treated as virtual filesystems and Collections can
        be made from paths and layers within them. In other words, Fiona lets you read
        and write zipped Shapefiles.
        
        .. code-block:: python
        
            with fiona.drivers():
        
                for i, layername in enumerate(
                        fiona.listlayers(
                            '/', 
                            vfs='zip://tests/data/coutwildrnp.zip')):
                    with fiona.open(
                            '/', 
                            vfs='zip://tests/data/coutwildrnp.zip', 
                            layer=i) as src:
                        print(i, layername, len(src))
            
            # Output:
            # (0, u'coutwildrnp', 67)
        
        Fiona CLI
        =========
        
        Fiona's command line interface, named "fio", is documented at `docs/cli.rst
        <https://github.com/Toblerity/Fiona/blob/master/docs/cli.rst>`__. Its ``fio
        info`` pretty prints information about a data file.
        
        .. code-block:: console
        
            $ fio info --indent 2 tests/data/coutwildrnp.shp
            {
              "count": 67,
              "crs": "EPSG:4326",
              "driver": "ESRI Shapefile",
              "bounds": [

                -104.97087097167969,
                41.99627685546875

                  "NAME": "str:80",
                  "FEATURE1": "str:80",
                  "URL": "str:101",
                  "AGBUR": "str:80",

                  "WILDRNP020": "int:10",
                  "STATE": "str:80"
                }
              }
            }
        
        Installation
        ============
        
        Fiona requires Python 2.6, 2.7, 3.3, or 3.4 and GDAL/OGR 1.8+. To build from
        a source distribution you will need a C compiler and GDAL and Python
        development headers and libraries (libgdal1-dev for Debian/Ubuntu, gdal-dev for
        CentOS/Fedora).
        
        To build from a repository copy, you will also need Cython to build C sources
        from the project's .pyx files. See the project's requirements-dev.txt file for
        guidance.
        
        The `Kyngchaos GDAL frameworks
        <http://www.kyngchaos.com/software/frameworks#gdal_complete>`__ will satisfy
        the GDAL/OGR dependency for OS X, as will Homebrew's GDAL Formula (``brew install
        gdal``).
        
        Python Requirements
        -------------------
        
        Fiona depends on the modules ``six``, ``cligj``, ``argparse``, and
        ``ordereddict`` (the two latter modules are standard in Python 2.7+). Pip will
        fetch these requirements for you, but users installing Fiona from a Windows
        installer must get them separately.
        
        Unix-like systems
        -----------------
        
        Assuming you're using a virtualenv (if not, skip to the 4th command) and
        GDAL/OGR libraries, headers, and `gdal-config`_ program are installed to well
        known locations on your system via your system's package manager (``brew
        install gdal`` using Homebrew on OS X), installation is this simple.
        
        .. code-block:: console
        
          $ mkdir fiona_env
          $ virtualenv fiona_env
          $ source fiona_env/bin/activate
          (fiona_env)$ pip install Fiona
        
        If gdal-config is not available or if GDAL/OGR headers and libs aren't
        installed to a well known location, you must set include dirs, library dirs,
        and libraries options via the setup.cfg file or setup command line as shown
        below (using ``git``).
        
        .. code-block:: console
        
          (fiona_env)$ git clone git://github.com/Toblerity/Fiona.git
          (fiona_env)$ cd Fiona
          (fiona_env)$ python setup.py build_ext -I/path/to/gdal/include -L/path/to/gdal/lib -lgdal install
        
        Or specify that build options should be provided by a particular
        gdal-config program.
        
        .. code-block:: console
        
          (fiona_env)$ GDAL_CONFIG=/path/to/gdal-config pip install .
        
        Windows
        -------
        
        Binary installers are available at
        http://www.lfd.uci.edu/~gohlke/pythonlibs/#fiona and coming eventually to PyPI.
        
        You can download a binary distribution of GDAL from `here
        <http://www.gisinternals.com/release.php>`_.  You will also need to download
        the compiled libraries and headers (include files).
        
        When building from source on Windows, it is important to know that setup.py
        cannot rely on gdal-config, which is only present on UNIX systems, to discover 
        the locations of header files and libraries that Fiona needs to compile its 
        C extensions. On Windows, these paths need to be provided by the user. 
        You will need to find the include files and the library files for gdal and 
        use setup.py as follows.
        
        .. code-block:: console
        
            $ python setup.py build_ext -I<path to gdal include files> -lgdal_i -L<path to gdal library>
            $ python setup.py install
        
        Note: The GDAL dll (gdal111.dll) and gdal-data directory need to be in your 
        Windows PATH otherwise Fiona will fail to work.
        
        Development and testing
        =======================
        
        Building from the source requires Cython. Tests require Nose. If the GDAL/OGR
        libraries, headers, and `gdal-config`_ program are installed to well known
        locations on your system (via your system's package manager), you can do this::
        
          (fiona_env)$ git clone git://github.com/Toblerity/Fiona.git
          (fiona_env)$ cd Fiona
          (fiona_env)$ pip install -e .
          (fiona_env)$ nosetests
        
        If you have a non-standard environment, you'll need to specify the include and
        lib dirs and GDAL library on the command line::
        
          (fiona_env)$ python setup.py build_ext -I/path/to/gdal/include -L/path/to/gdal/lib -lgdal develop
          (fiona_env)$ nosetests

        -----------------
        - Cythonize .pyx files (#34).
        - Work with or around OGR's internal recoding of record data (#35).
        - Fix bug in serialization of int/float PROJ.4 params.

        ------------------
        - Silence the logger in ogrext.so (can be overridden).
        - Allow user specification of record field encoding (like 'Windows-1252' for
          Natural Earth shapefiles) to help when OGR can't detect it.
        
        0.9 (2013-03-06)
        ----------------
        - Accessing file metadata (crs, schema, bounds) on never inspected closed files

        - Add validate_record method to collections.
        - Add helpful coordinate system functions to fiona.crs.
        - Promote use of fiona.open over fiona.collection.
        - Handle Shapefile's mix of LineString/Polygon and multis (#18).
        - Allow users to specify width of shapefile text fields (#20).
        
        0.8 (2012-02-21)
        ----------------
        - Replaced .opened attribute with .closed (product of collection() is always
          opened). Also a __del__() which will close a Collection, but still not to be
          depended upon.
        - Added writerecords method.
        - Added a record buffer and better counting of records in a collection.
        - Manage one iterator per collection/session.

        0.7 (2012-01-29)
        ----------------
        - Initial timezone-naive support for date, time, and datetime fields. Don't use
          these field types if you can avoid them. RFC 3339 datetimes in a string field
          are much better.

        ------------------
        - Diagnose and set the driver property of collection in read mode.
        - Fail if collection paths are not to files. Multi-collection workspaces are
          a (maybe) TODO.
        
        0.6.1 (2012-01-06)
        ------------------
        - Handle the case of undefined crs for disk collections.
        
        0.6 (2012-01-05)
        ----------------
        - Support for collection coordinate reference systems based on Proj4.
        - Redirect OGR warnings and errors to the Fiona log.
        - Assert that pointers returned from the ograpi functions are not NULL before
          using.
        
        0.5 (2011-12-19)
        ----------------
        - Support for reading and writing collections of any geometry type.
        - Feature and Geometry classes replaced by mappings (dicts).
        - Removal of Workspace class.
        
        0.2 (2011-09-16)
        ----------------
        - Rename WorldMill to Fiona.
        
        0.1.1 (2008-12-04)
        ------------------
