OWSLib 0.11.0

OGC Web Service utility library

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

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


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


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

>>> from owslib.wms import WebMapService
>>> wms = WebMapService('', version='1.1.1')
>>> wms.identification.type
>>> wms.identification.version
>>> 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',

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:

>>> [ for op in wms.operations]
['GetTileService', 'GetCapabilities', 'GetMap']
>>> wms.getOperationByName('GetMap').methods
{'Get': {'url': ''}}
>>> 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(
>>> 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.


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)
