OWSLib
======

OWSLib is a Python package for client programming with Open Geospatial
Consortium (OGC) web service (hence OWS) interface standards, and their
related content models.

Full documentation is available at http://geopython.github.io/OWSLib

OWSLib provides a common API for accessing service metadata and wrappers for
numerous OGC Web Service interfaces.

Dependencies
------------

OWSLib requires elementtree (standard in 2.5 as xml.etree) or lxml.

Usage
-----

Find out what a WMS has to offer. Service metadata::

    >>> from owslib.wms import WebMapService
    >>> wms = WebMapService('http://wms.jpl.nasa.gov/wms.cgi', version='1.1.1')
    >>> wms.identification.type
    'OGC:WMS'
    >>> wms.identification.version
    '1.1.1'
    >>> wms.identification.title
    'JPL Global Imagery Service'
    >>> wms.identification.abstract
    'WMS Server maintained by JPL, worldwide satellite imagery.'

Available layers::

    >>> list(wms.contents)
    ['us_landsat_wgs84', 'modis', 'global_mosaic_base', 'huemapped_srtm',
    'srtm_mag', 'daily_terra', 'us_ned', 'us_elevation', 'global_mosaic',
    'daily_terra_ndvi', 'daily_aqua_ndvi', 'daily_aqua_721', 'daily_planet',
    'BMNG', 'srtmplus', 'us_colordem', None, 'daily_aqua', 'worldwind_dem',
    'daily_terra_721']

Details of a layer::

    >>> wms['global_mosaic'].title
    'WMS Global Mosaic, pan sharpened'
    >>> wms['global_mosaic'].boundingBoxWGS84
    (-180.0, -60.0, 180.0, 84.0)
    >>> wms['global_mosaic'].crsOptions
    ['EPSG:4326', 'AUTO:42003']
    >>> wms['global_mosaic'].styles
    {'pseudo_bright': {'title': 'Pseudo-color image (Uses IR and Visual bands,
    542 mapping), gamma 1.5'}, 'pseudo': {'title': '(default) Pseudo-color
    image, pan sharpened (Uses IR and Visual bands, 542 mapping), gamma 1.5'},
    'visual': {'title': 'Real-color image, pan sharpened (Uses the visual
    bands, 321 mapping), gamma 1.5'}, 'pseudo_low': {'title': 'Pseudo-color
    image, pan sharpened (Uses IR and Visual bands, 542 mapping)'},
    'visual_low': {'title': 'Real-color image, pan sharpened (Uses the visual
    bands, 321 mapping)'}, 'visual_bright': {'title': 'Real-color image (Uses
    the visual bands, 321 mapping), gamma 1.5'}}

Available methods, their URLs, and available formats::

    >>> [op.name for op in wms.operations]
    ['GetTileService', 'GetCapabilities', 'GetMap']
    >>> wms.getOperationByName('GetMap').methods
    {'Get': {'url': 'http://wms.jpl.nasa.gov/wms.cgi?'}}
    >>> wms.getOperationByName('GetMap').formatOptions
    ['image/jpeg', 'image/png', 'image/geotiff', 'image/tiff']

That's everything needed to make a request for imagery::

    >>> img = wms.getmap(   layers=['global_mosaic'],
    ...                     styles=['visual_bright'],
    ...                     srs='EPSG:4326',
    ...                     bbox=(-112, 36, -106, 41),
    ...                     size=(300, 250),
    ...                     format='image/jpeg',
    ...                     transparent=True
    ...                     )
    >>> out = open('jpl_mosaic_visb.jpg', 'wb')
    >>> out.write(img.read())
    >>> out.close()

A very similar API exists for WebFeatureService. See
tests/wfs_MapServerWFSCapabilities.txt for details.

There is also support for Web Coverage Service (WCS), Catalogue
Service for the Web (CSW), Web Processing Service (WPS), and Web
Map Tile Service (WMTS). Some of those are beta quality.
