I followed the instructions from
http://docs.geoserver.org/stable/en/user/tutorials/imagepyramid/imagepyramid.html
to create image pyramids for two files.
shaded_dem.tif is a UINT16 GeoTIFF.
dem.tif is a Float64 GeoTiff.
I used this command to create the shaded dem: gdal_retile.py -v -ot UInt16
-levels 6 -ps 1024 1024 -co "TILED=YES" -targetDir shaded_dem shaded_dem.tif
I used this command to create the DEM: gdal_retile.py -v -levels 6 -ps 1024
1024 -co "TILED=YES" -targetDir dem dem.tif

When I drag/drop the WMS layer into ArcMap (similar in QGIS), I get this
error "One or more layers failed to draw:
WMS: WMS service exceptions:Service Error Description:
java.lang.NullPointerException"
The partial geoserver log entry for this is:
RawKvp = {CRS=CRS:84, FORMAT=image/png, BGCOLOR=0xFEFFFF, STYLES=,
WIDTH=776, HEIGHT=415, LAYERS=pioneer:shaded_dem_6_1024, EXCEPTIONS=XML,

java.lang.NullPointerException
If I then go into ArcMap and change the image type of the WMS to "JPG" from
"PNG", the image renders correctly. In QGIS, when I load the WMS layer with
PNG, it does not display (but I can click on it to get values). When I load
the layer in QGIS using JPG, it renders properly.
I am not sure what is different between the two images other than their
data type. One is floating64 and the other is UINT16.
Thanks
Mark
