Hi Ivan getDescribeCoverage gets an ElementTree object, not the actual XML.
However you shouldn't need to do that actually - that method is just there as
an 'extra'.
the way to do it is:
from owslib.wcs import WebCoverageService
wcs =
WebCoverageService('http://geoserver.irpi.cnr.it/geoserver/wcs',version='1.0.0')
wcs.contents #prints available coverages
cvg=wcs['irpi:collazzone_2004'] #this gives you a coverage metadata object to
interrogate
#look at the coverage properties:
cvg.boundingBoxWGS84
cvg.timepositions
cvg.supportedCRS
cvg.supportedFormats
make get coverage request:
u=wcs.getCoverage(identifier='irpi:collazzone_2004', bbox=
(12.7, 42.5, 13, 43) , crs='EPSG:32633', format='PNG', width=100, height=100)
u.read()
Then you get a geoserver exception:
'<?xml version="1.0" encoding="UTF-8"?><ServiceExceptionReport version="1.2.0"
xmlns="http://www.opengis.net/ogc";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/ogc
http://schemas.opengis.net/wcs/1.0.0/OGC-exception.xsd";> <ServiceException
code="problem with CoverageResults">\n
org.vfny.geoserver.wcs.WcsException: The Intersection is null. Check the
requested BBOX!\nThe Intersection is null. Check the requested
BBOX!\n</ServiceException></ServiceExceptionReport>'
This error response seems odd as the bounding box I requested is within your
bounds...
Anyway, hope that helps.
Cheers,
Dom

I think adding the version parameter the getCapabilities works:
http://geoserver.irpi.cnr.it/geoserver/wcs?version=1.0.0&service=WCS&REQUEST=getcapabilities
but the problem is still:
___________
from owslib.wcs import WebCoverageService
wcs = WebCoverageService('http://geoserver.irpi.cnr.it/geoserver/wcs',
version='1.0.0')
description=wcs.getDescribeCoverage('irpi:collazzone_2004')
______________
from which I can't see anything inside "description".. :-(
many thanks...
