I'm fairly new at WCS so bear with me if this is a really stupid question, but I can't really understand the problem. I'm trying to retrieve some DEM data from the Italian Ministry of Environment's freely available datasets, which are structured as a Web Coverage Service. In the capabilities of the dataset I'm interested into (http://wms.pcn.minambiente.it/wcs/dtm_75m?service=wcs&request=getCapabilities) it clearly states that the Bounding Box limits are the following:
<ows:WGS84BoundingBox dimensions="2"> <ows:LowerCorner>6.53911455679 35.2154346311</ows:LowerCorner> <ows:UpperCorner>19.6147808261 47.1364182243</ows:UpperCorner> </ows:WGS84BoundingBox>
But if I try to send the following getCoverage request:
The server keeps returning me this error:
<ows:ExceptionReport xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ows="http://www.opengis.net/ows/1.1" version="1.1.2" xml:lang="en-US" xsi:schemaLocation="http://www.opengis.net/ows/1.1 http://schemas.opengis.net/ows/1.1.0/owsExceptionReport.xsd"> <ows:Exception exceptionCode="width/height" locator="InvalidParameterValue"> <ows:ExceptionText> msWCSGetCoverage(): WCS server error. Raster size out of range, width and height of resulting coverage must be no more than MAXSIZE=2048. </ows:ExceptionText> </ows:Exception> </ows:ExceptionReport>
Why is that? Where's the error?
I tried also to swap Lon and Lat duplets or give them in the cartesian coordinates of the dataset, but to no avail...
Thanks for your help!
