I've decided to leave it for now and just use a fixed 10 metre resolution
instead. However, I can't get my GetCoverage request to work with
GeoServer. For example, the following request:
http://localhost:8080/geoserver/wcs?service=WCS&version=1.0.0&request=GetCoverage&coverage=L5203023_02320060610_B10&bbox=-2.2845935058594,52.851759765624,-1.6830920410156,53.263747070312&crs=EPSG:4326&response_crs=EPSG:32630&format=geotiff&resx=10&resy=10
produces the following error:
<?xml version="1.0" encoding="UTF-8"?><ServiceExceptionReport
version="1.2.0" xmlns="http://www.opengis.net/ogc"; xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="

http://localhost:8080/geoserver/schemas/wcs/1.0.0/OGC-exception.xsd";>
<ServiceException code="problem with CoverageResults">
org.vfny.geoserver.wcs.WcsException: Neither Grid Size nor Grid
Resolution have been specified.
Neither Grid Size nor Grid Resolution have been specified.
</ServiceException></ServiceExceptionReport>
However, as you can see, I've included the resx and resy parameters in my
request.
Am I doing something wrong or is this a bug?
Thanks,
Jon
