Dear All Can anyone help me with trying to get a WCS 1.0.0 GetCoverage request to work with THREDDS? I'm using THREDDS 4.6.3 and get expected XML responses when I attempt WCS GetCapabilities and DescribeCoverage requests. However, when I attempt a GetCoverage request, with format equal to GeoTIFF or NetCDF3, I get a "This web page is not available ERR_INVALID_RESPONSE" error and when I show the details I'm told that "The web page at... ...might be temporarily down or it may have moved permenantly to a new web address." I tried this initially with gridded data in a British National Grid projection and the GetCoverage request fails. I therefore created a dummy netCDF file with a latitude longitude projection and have configured a THREDDS instance in a VM on my local machine to test but I am still getting the same error - the GetCapabilities and DescribeCoverage requests work and the GetCoverage request fails. The form of the WCS requests I'm attempting are as follows: http://localhost:8080/thredds/wcs/smwtestwcs/chess_tas_196101_modified.nc?service=WCS&version=1.0.0&request=GetCapabilities http://localhost:8080/thredds/wcs/smwtestwcs/chess_tas_196101_modified.nc?service=WCS&version=1.0.0&request=DescribeCoverage&coverage=tas http://localhost:8080/thredds/wcs/smwtestwcs/chess_tas_196101_modified.nc?service=WCS&version=1.0.0&request=GetCoverage=tas&time=1961-01-31T00:00:00Z&format=GeoTIFF http://localhost:8080/thredds/wcs/smwtestwcs/chess_tas_196101_modified.nc?service=WCS&version=1.0.0&request=GetCoverage=tas&time=1961-01-31T00:00:00Z&format=NetCDF3 I have used ToolsUI 4.6 to check that the dummy netCDF file is OK and I can successfully display the gridded data in a netCDF file using the FeatureTypes | Grid tab. I can also display the dummy netCDF file in the Godiva2 viewer in the VM THREDDS instance. The metadata header of the dummy netCDF file is as follows: netcdf C:/smw/Workspace/THREDDS_WCS/Data02/dummy.nc { dimensions: latitude = 6; longitude = 12; variables: float latitude(latitude=6); :_CoordinateAxisType = "Lat"; :units = "degrees_north"; int crs; :grid_mapping_name = "latitude_longitude"; :longitude_of_prime_meridian = 0.0; // double :semi_major_axis = 6378137.0; // double :inverse_flattening = 298.257225363; // double :_CoordinateTransformType = "Projection"; :_CoordinateAxes = "x y"; float longitude(longitude=12); :_CoordinateAxisType = "Lon"; :units = "degrees_east"; float pressure(latitude=6, longitude=12); :_CoordinateAxes = "x y"; :coordinates = "y x"; :long_name = "Pressure"; :units = "hPa"; :grid_mapping = "crs"; float temperature(latitude=6, longitude=12); :_CoordinateAxes = "x y"; :coordinates = "y x"; :long_name = "Temperature"; :units = "celsius"; :grid_mapping = "crs"; // global attributes: :cdm_data_type = "GRID"; :Conventions = "CF-1.0"; :featureType = "GRID"; } The netCDF file in the British National Grid can also be displayed in ToolsUI 4.6 and Godiva2 viewers. Can anyone shed any light on what I might be doing wrong and why I can't get a GetCoverage WVS request to work? Many thanks, best wishes, Simon. ________________________________ This message (and any attachments) is for the recipient only.
