Hi, I am trying to understand something about WCS 2.x but I do not quite understand how the trimming should be done.
I am playing with Geoserver 2.7.2 and the standard demo layers. GetCapabilities I am getting with http://localhost:8080/geoserver/ows?service=WCS&version=2.0.1&request=GetCapabilities If am interested in the coverage "nurc__Pk50095" I read more info with http://localhost:8080/geoserver/ows?service=WCS&version=2.0.1&request=describecoverage&coverageid=nurc__Pk50095 (BTW, after installing Geoserver both the store and layer must be activated from the config utility before Pk50095 can be used.) So, now I can read the extents of this coverage and they are <gml:Envelope srsName="http://www.opengis.net/def/crs/EPSG/0/32633"; axisLabels="E N" uomLabels="m m" srsDimension="2"> <gml:lowerCorner>5176214.082539256 347649.93086859107</gml:lowerCorner> <gml:upperCorner>5196961.352859256 370725.976428591</gml:upperCorner> </gml:Envelope> Ok, wonderful to see an OGC service where axis order is finally defined so that nothing can go wrong. I'll put Easting first and Northing next and go trimming: localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&coverageid=nurc__Pk50095&format=image/tiff&subset=E("5176214","5186214")&subset=N("347649","357649") But the result is: <ows:Exception exceptionCode="InvalidSubsetting" locator=""><ows:ExceptionText>Empty intersection after subsetting[] </ows:ExceptionText> </ows:Exception> Changing the axis labels makes the request to work: localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&coverageid=nurc__Pk50095&format=image/tiff&subset=N("5176214","5186214")&subset=E("347649","357649") I wonder what is going wrong this time. Is it that GeoServer sends the coordinates of the Envelope or the axis labels in wrong order? If I check the source image with gdalinfo I can see that the first coordinates in the advertised envelope are actually northings Upper Left ( 347649.931, 5196961.353) Lower Left ( 347649.931, 5176214.083) Upper Right ( 370725.976, 5196961.353) Lower Right ( 370725.976, 5176214.083) -Jukka Rahkonen- ------------------------------------------------------------------------------ _______________________________________________ Geoserver-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/geoserver-users
