[gdal-dev] Geoserver WCS demo problems on opengeo.org

[Radim Blazek]

I am testing QGIS WCS client with [1] and I found some problems which
are server side, I believe.

1) Coverage og:0 / version 1.0.0  [2] and bm / version 1.1.0 [5]: The
server fails in DescribeCoverage with: java.io.IOException null
Translator error Unexpected error occurred during describe coverage
xml encoding ...

2) Coverage usgs:nlcd / version 1.0.0 [3] and nlcd / version 1.1.0
[4]:  The server does not offer any CRS in DescribeCoverage
supportedCRSs / supportedCRS. If the CRS defined in
spatialDomain.Envelope is used server fails reporting error: Could not
recognize crs ...

3) Coverage 0 / version 1.1.0 [6] and naturalearth / version 1.1.0:
The server fails in GetCoverage with
'java.lang.IllegalArgumentException: xScale:the parameter value is not
valid. xScale:the parameter value is not valid.'
It fails with BOUNDINGBOX=-2,-6,2,6&GRIDORIGIN=2,-6&GRIDOFFSETS=-2,3
and it works with
BOUNDINGBOX=-2,-6,2,6&GRIDORIGIN=2,-6&GRIDOFFSETS=2,-3 (GRIDOFFSETS
signs switched) but other coverages (Arc_Sample e.g.) work OK with the
first.

4) Coverage Img_Sample / version 1.1.0 [7]: The server fails in
GetCoverage with 'java.lang.IllegalArgumentException: The specified
dimensional parameter is non-positive. The specified dimensional
parameter is non-positive'.

The problems 1) and 2) occur also with GDAL 1.9.1 while other layers
are working with GDAL and WCS version 1.0.0. I could not verify WCS
1.1.0 with GDAL because all layers fail. I could not verify with
gvSIG-1_11-1305-final because it does not work at all with this
server.

CC to various lists to which it may be of interest. Let us make WCS
really working with OS GIS tools!
