Hi Goyo, I've modified the code in the owslib trunk now to better handle url encodings and the returned error.
However it is only a quick fix and I need to review it more thoroughly (this aspect needs reviewing throughout owslib). I had some success accessing your server, until the final getcoverage request which returns an error I don't understand: <?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?><!DOCTYPE ServiceExceptionReport SYSTEM "http://www.idee.es/wcs/dtd/exception_1_1_0.dtd";><ServiceExceptionReport version="1.1.0"><ServiceException code="InvalidFormat">Error al parsear la peticion XML: Start of root element expected.</ServiceException></ServiceExceptionReport> The code I used to test it (and the responses) was this: >>> from owslib.wcs import WebCoverageService >>> wcs=WebCoverageService('http://www.idee.es/wcs/IDEE-WCS-UTM30N/wcsServlet', version='1.0.0') >>> wcs.url 'http://www.idee.es/wcs/IDEE-WCS-UTM30N/wcsServlet' >>> wcs.version '1.0.0' >>> wcs.identification.service 'IDEE-WCS-UTM30N' >>> wcs.provider.name 'IAAA Laboratory, University of Zaragoza' >>> wcs.provider.contact.organization 'IAAA Laboratory, University of Zaragoza' >>> wcs.contents.keys() ['MDT25_peninsula_pendientes', 'MDT_peninsula_baleares_aspecto', 'MDT1000_peninsula_baleares', 'MDT500_peninsula_baleares', 'MDT_peninsula_baleares', 'MDT500_peninsula_baleares_pendientes', 'MDT1000_peninsula_baleares_pendientes', 'MDT_peninsula_baleares_pendientes', 'MDT25_peninsula_ZIP', 'MDT25_peninsula_aspecto', 'MDT500_peninsula_baleares_aspecto', 'MDT1000_peninsula_baleares_aspecto'] >>> cvg=wcs['MDT25_peninsula_pendientes'] >>> cvg.title 'MDT25 Pendientes Peninsula' >>> cvg.boundingBoxWGS84 (-8.7527311628, 35.8849011171, 3.6409641687000001, 43.7511638541) >>> cvg.timelimits [] >>> cvg.supportedFormats ['GeoTIFF', 'AsciiGrid', 'FloatGrid_Zip'] >>> cvg.supportedCRS ['EPSG:4326', 'EPSG:4230', 'EPSG:23028', 'EPSG:23029', 'EPSG:23030', 'EPSG:23031', 'EPSG:23030'] >>> output=wcs.getCoverage(identifier='MDT25_peninsula_pendientes',bbox=(-8,37,2,40), crs='EPSG:4326', format='GeoTIFF', resX=1, resY=1) >>> f=open('test.tif', 'wb') >>> f.write(output.read()) >>> f.close() If you look in the test.tif file you see the error.
