[Geoserver-users] 16 bit Geotiffs using WMS

Hello,

When I try to render a 16 bit DEM (containing Coverages) with geoserver
using WMS with Qgis.All i get is a blank page.

My Process Steps were as follows:

I used GDAL_translate to convert a DEM into a 16 or 8 bit GeoTiff.The
GeoTiff opens fine if Qgis reads it from the file but,if i load it into
Geoserver and try to render it using WMS, the ouput is simply a blank
page!!!!

if anybody has any suggestions,i would appreciate,
Thanks
Sharat

Ciao,
a sample file and a Jira task for it would be greatly appreciated.

Keep in mind also that for the moment the implementation of
RasterSymbolizer is quite poor hence your DEM data could not be
rendered very nicely.

Hmmm... mine is just a guess, but try to associate the following SLD to
your raster:

<?xml version="1.0" encoding="UTF-8"?>
<StyledLayerDescriptor xmlns="http://www.opengis.net/sld&quot; xmlns:ogc="http://www.opengis.net/ogc&quot; xmlns:xlink="http://www.w3.org/1999/xlink&quot; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot; xsi:schemaLocation="http://www.opengis.net/sld
http://schemas.opengis.net/sld/1.0.0/StyledLayerDescriptor.xsd&quot; version="1.0.0">
<UserLayer>
   <Name>raster_layer</Name>
         <LayerFeatureConstraints>
             <FeatureTypeConstraint/>
         </LayerFeatureConstraints>
   <UserStyle>
     <Name>raster</Name>
     <Title>A boring default style</Title>
