Description: 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.
