        Rasterio
        ========
        
        Rasterio reads and writes geospatial raster data.

        Geographic information systems use GeoTIFF and other formats to organize and
        store gridded, or raster, datasets. Rasterio reads and writes these formats and
        provides a Python API based on N-D arrays.
        
        Rasterio supports Python 2.7 and 3.3-3.6 on Linux and Mac OS X.
        
        Read the documentation for more details: https://rasterio.readthedocs.io/en/latest/.
        
        Example
        =======
        
        Here's an example of some basic features that Rasterio provides. Three bands
        are read from an image and averaged to produce something like a panchromatic
        band.  This new band is then written to a new single band TIFF.
        
        .. code-block:: python
        
            import numpy as np
            import rasterio
        
            # Read raster bands directly to Numpy arrays.
            #
            with rasterio.open('tests/data/RGB.byte.tif') as src:
                r, g, b = src.read()
        
            # Combine arrays in place. Expecting that the sum will
            # temporarily exceed the 8-bit integer range, initialize it as
            # a 64-bit float (the numpy default) array. Adding other
            # arrays to it in-place converts those arrays "up" and
            # preserves the type of the total array.
            total = np.zeros(r.shape)
            for band in r, g, b:
                total += band
            total /= 3
        
            # Write the product as a raster band to a new 8-bit file. For
            # the new file's profile, we start with the meta attributes of
            # the source file, but then change the band count to 1, set the
            # dtype to uint8, and specify LZW compression.
            profile = src.profile
            profile.update(dtype=rasterio.uint8, count=1, compress='lzw')
        
            with rasterio.open('example-total.tif', 'w', **profile) as dst:
                dst.write(total.astype(rasterio.uint8), 1)
        
        The output:

        API Overview
        ============
        
        Rasterio gives access to properties of a geospatial raster file.
        
        .. code-block:: python
        
            with rasterio.open('tests/data/RGB.byte.tif') as src:
                print(src.width, src.height)
                print(src.crs)
                print(src.transform)
                print(src.count)
                print(src.indexes)
        
            # Printed:
            # (791, 718)
            # {u'units': u'm', u'no_defs': True, u'ellps': u'WGS84', u'proj': u'utm', u'zone': 18}
            # Affine(300.0379266750948, 0.0, 101985.0,
            #        0.0, -300.041782729805, 2826915.0)
            # 3
            # [1, 2, 3]
        
        A rasterio dataset also provides methods for getting extended array slices given
        georeferenced coordinates.
        
        
        .. code-block:: python
        
            with rasterio.open('tests/data/RGB.byte.tif') as src:
                print src.window(**src.window_bounds(((100, 200), (100, 200))))
        
            # Printed:
            # ((100, 200), (100, 200))
        
        Rasterio CLI
        ============
        
        Rasterio's command line interface, named "rio", is documented at `cli.rst
        <https://github.com/mapbox/rasterio/blob/master/docs/cli.rst>`__. Its ``rio
        insp`` command opens the hood of any raster dataset so you can poke around
        using Python.
        
        .. code-block:: pycon
        
            $ rio insp tests/data/RGB.byte.tif
            Rasterio 0.10 Interactive Inspector (Python 3.4.1)
            Type "src.meta", "src.read(1)", or "help(src)" for more information.
            >>> src.name
            'tests/data/RGB.byte.tif'
            >>> src.closed
            False
            >>> src.shape
            (718, 791)
            >>> src.crs
            {'init': 'epsg:32618'}
            >>> b, g, r = src.read()
            >>> b
            masked_array(data =
             [[-- -- -- ..., -- -- --]
             [-- -- -- ..., -- -- --]
             [-- -- -- ..., -- -- --]
             ...,
             [-- -- -- ..., -- -- --]
             [-- -- -- ..., -- -- --]
             [-- -- -- ..., -- -- --]],
                         mask =
             [[ True  True  True ...,  True  True  True]
             [ True  True  True ...,  True  True  True]
             [ True  True  True ...,  True  True  True]
             ...,
             [ True  True  True ...,  True  True  True]
             [ True  True  True ...,  True  True  True]
             [ True  True  True ...,  True  True  True]],
                   fill_value = 0)
        
            >>> np.nanmin(b), np.nanmax(b), np.nanmean(b)
            (0, 255, 29.94772668847656)
        
        Rio Plugins
        -----------
        
        Rio provides the ability to create subcommands using plugins.  See
        `cli.rst <https://github.com/mapbox/rasterio/blob/master/docs/cli.rst#rio-plugins>`__
        for more information on building plugins.
        
        See the
        `plugin registry <https://github.com/mapbox/rasterio/wiki/Rio-plugin-registry>`__
        for a list of available plugins.
        
        
        Installation
        ============
        
        Please install Rasterio in a `virtual environment
        <https://www.python.org/dev/peps/pep-0405/>`__ so that its requirements don't
        tamper with your system's Python.
        
        SSL certs
        ---------
        
        The Linux wheels on PyPI are built on CentOS and libcurl expects certs to be in
        /etc/pki/tls/certs/ca-bundle.crt. Ubuntu's certs, for example, are in
        a different location. You may need to use the CURL_CA_BUNDLE environment
        variable to specify the location of SSL certs on your computer. On an Ubuntu
        system set the variable as shown below.
        
        .. code-block:: console
        
            $ export CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
        
        
        Dependencies
        ------------
        
        Rasterio has a C library dependency: GDAL >=1.11. GDAL itself depends on some other libraries provided by most major operating systems and also
        depends on the non standard GEOS and PROJ4 libraries. How to meet these
        requirement will be explained below.
        
        Rasterio's Python dependencies are listed in its requirements.txt file.
        
        Development also requires (see requirements-dev.txt) Cython and other packages.
        
        Binary Distributions
        --------------------
        
        Use a binary distributions that directly or indirectly provide GDAL if
        possible.
        
        Linux
        +++++
        
        Rasterio distributions are available from UbuntuGIS and Anaconda's conda-forge
        channel.
        
        `Manylinux1 <https://github.com/pypa/manylinux>`__ wheels are available on PyPI.```
        
        OS X
        ++++
        
        Binary distributions with GDAL, GEOS, and PROJ4 libraries included are available
        for OS X versions 10.7+ starting with Rasterio version 0.17. To install,
        run ``pip install rasterio``. These binary wheels are preferred by newer
        versions of pip.
        
        If you don't want these wheels and want to install from a source distribution,
        run ``pip install rasterio --no-binary rasterio`` instead.
        
        The included GDAL library is fairly minimal, providing only the format drivers
        that ship with GDAL and are enabled by default. To get access to more formats,
        you must build from a source distribution (see below).
        
        Windows
        +++++++
        
        Binary wheels for rasterio and GDAL are created by Christoph Gohlke and are
        available from his website.
        
        To install rasterio, simply download both binaries for your system (`rasterio
        <http://www.lfd.uci.edu/~gohlke/pythonlibs/#rasterio>`__ and `GDAL
        <http://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal>`__) and run something like
        this from the downloads folder:
        
        .. code-block:: console
        
            $ pip install -U pip
            $ pip install GDAL-2.0.2-cp27-none-win32.whl
            $ pip install rasterio-0.34.0-cp27-cp27m-win32.whl
        
        You can also install rasterio with conda using Anaconda's conda-forge channel.
        
        .. code-block:: console
        
            $ conda install -c conda-forge rasterio 
        
        
        Source Distributions
        --------------------
        
        Rasterio is a Python C extension and to build you'll need a working compiler
        (XCode on OS X etc). You'll also need Numpy preinstalled; the Numpy headers are
        required to run the rasterio setup script. Numpy has to be installed (via the
        indicated requirements file) before rasterio can be installed. See rasterio's
        Travis `configuration
        <https://github.com/mapbox/rasterio/blob/master/.travis.yml>`__ for more
        guidance.
        
        Linux
        +++++
        
        The following commands are adapted from Rasterio's Travis-CI configuration.
        
        .. code-block:: console
        
            $ sudo add-apt-repository ppa:ubuntugis/ppa
            $ sudo apt-get update
            $ sudo apt-get install gdal-bin libgdal-dev
            $ pip install -U pip
            $ pip install rasterio
        
        Adapt them as necessary for your Linux system.
        
        OS X
        ++++
        
        For a Homebrew based Python environment, do the following.
        
        .. code-block:: console
        
            $ brew update
            $ brew install gdal
            $ pip install -U pip
            $ pip install --no-use-wheel rasterio
        
        Alternatively, you can install GDAL binaries from `kyngchaos
        <http://www.kyngchaos.com/software/frameworks#gdal_complete>`__.  You will then
        need to add the installed location ``/Library/Frameworks/GDAL.framework/Programs``
        to your system path.
        
        Windows
        +++++++
        
        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 rasterio 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
        
        We have had success compiling code using the same version of Microsoft's
        Visual Studio used to compile the targeted version of Python (more info on
        versions used `here
        <https://docs.python.org/devguide/setup.html#windows>`__.).
        
        Note: The GDAL dll (gdal111.dll) and gdal-data directory need to be in your
        Windows PATH otherwise rasterio will fail to work.
        
        
        Support
        =======
        
        The primary forum for questions about installation and usage of Rasterio is
        https://rasterio.groups.io/g/main. The authors and other users will answer
        questions when they have expertise to share and time to explain. Please take
        the time to craft a clear question and be patient about responses.
        
        Please do not bring these questions to Rasterio's issue tracker, which we want
        to reserve for bug reports and other actionable issues.
        
        While Rasterio's repo is in the Mapbox GitHub organization, Mapbox's Support
        team is focused on customer support for its commercial platform and Rasterio
        support requests may be perfunctorily closed with or without a link to
        https://rasterio.groups.io/g/main. It's better to bring questions directly to
        the main Rasterio group at groups.io.
