[Geoserver-users] WCS Downloads

Hi,

a WCS DescribeCoverage request informs me that the following download
formats are supported: GIF, PNG, JPEG, TIFF, GTOPO30, GeoTIFF, IMAGEMOSAIC,
ARCGRID for a particular coverage. However, if I try a download in each
format I receive the following errors:

GIF: The specified ColorModel is incompatible with the image SampleModel.
PNG: Unable to render RenderedOp for this operation.
JPEG: Unable to render RenderedOp for this operation.
IMAGEMOSAIC: Output format: IMAGEMOSAIC not supported by geoserver for this
Coverage.
ARCGRID: Problems Rendering Image null.

GTOPO30 returns a 478 byte zip file that is corrupted (not a valid archive)

TIFF and GeoTIFF work fine.

Any idea why I receive the errors? Do I need extra plugins for formats other
than TIFF, GEOTIFF?

The original coverage file is in EPSG:3031 projection - not the standard
lat/long - is that an issue?

Any help appreciated,
Dave
