Latest commit c73c06e Jun 20, 2016 @kwilcox kwilcox committed with tomkralidis SOS2.0 and WaterML2.0 (#241)
* Some basic SOS2.0 calls

* Additions to decode get_observation responses from SOS2.0. Adding
support for decoding WaterML2.0 and general Observations & Measurement
types.

* Added a fees to the service identification class.

* Add missing procedure argument and remove the timeout

* Change prints to use the function call (py3)

* WaterML2 fixes and PEP8 cleanup

* Don't double encode parameters (openURL already encodes)

* Add observed_properties as a class attribute

* PEP8 in sos200 and utils

* Fixing 52n sos20 test, adding sos20/waterml2 test, removing broken test

* Revert to using README.txt

* Fix bad merge (duplicate lines)

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.


Logging
-------
OWSLib logs messages to the 'owslib' named python logger. You may
configure your application to use the log messages like so:

    >>> import logging
    >>> owslib_log = logging.getLogger('owslib')
    >>> # Add formatting and handlers as needed
    >>> owslib_log.setLevel(logging.DEBUG)
