Hi, What really happens when you run gdalinfo is that it tries to capture a small image for further investigations. The request is
GET /geoserver/wcs?SERVICE=WCS&VERSION=1.1.0&REQUEST=GetCoverage&IDENTIFIER=raster_example_20130208_113005_078&FORMAT=image%2Ftiff%3Bsubtype%3D%22geotiff%22&BOUNDINGBOX=-116.917,32.41666843,-116.75033333,32.5833351,urn:ogc:def:crs:EPSG::4326&RangeSubset=contents HTTP/1.1 Host: 193.175.162.189 Accept: */* Accept-Encoding: gzip Proxy-Connection: Keep-Alive Geoserver does not like the request and it sends an error message which is <?xml version="1.0" encoding="UTF-8"?> <ows:ExceptionReport version="1.1.0" xsi:schemaLocation="http://www.opengis.net/ows/1.1 http://193.175.162.189:80/geoserver/schemas/ows/1.1.0/owsAll.xsd"; xmlns:ows="http://www.opengis.net/ows/1.1"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <ows:Exception exceptionCode="NoApplicableCode"> <ows:ExceptionText>java.lang.IllegalArgumentException: The specified dimensional parameter is non-positive.

If Geoserver folks will tell that the GDAL WCS 1.1.0 request is wrong then you can try to get an answer to question b) by sending a question with this information into GDAL developer mailing list. -Jukka Rahkonen- > -----Alkuperäinen viesti----- > Lähettäjä: Robert Kulawik [mailto:[email protected]] > Lähetetty: 8. helmikuuta 2013 13:29 > Vastaanottaja: [email protected] > Aihe: [Geoserver-users] Issue with noValue in WCS coverageOfferings > > Hi List, > > i have a problem with noValue (or nullValue) entrys in Geoserver's WCS and i > don't found a solution for it yet. > > I store a rasterfile, format ArcGrid, GeoTIFF and/or ErdasImg to Geoserver, > version 2.2.x, via REST interface and edit the coverage.xml to add some > missed entrys.
