Hello List
I have trouble to display overlaying rasters which contain topografic informations. The rasters are the german topografic map (DGK) which is represented by two layers: The base layer shows all roads and cities as value 0 rastercells, the relief layers shows all topolines as value 0 rastercells. The other cells have 1 as value. I translated them with gdal_translate to geotiff an set 1 as no_data value - which should get rid of those “no info cells”. In QGIS they show up properly and I can see both layers (1 value cells are transparent/ non existing). If used in GeoServer I am unable to see both layers, since the 1 value cells are rendered as white pixels. Something is wrong on the GeoServer side. Here are my settings:

Hi Floarian,
GeoServer historically has had no support for “nodata” pixels.
In version 2.8.0 we have a first implementation of nodata support, but it’s not enabled by default
as we have seen some misbehaviors in it.

If you want to try it out, get GeoServer 2.8.0 and add the following system variable declarations to the “java”
call running the web container for GeoServer (e.g., Tomcat, Jetty):

-Dorg.geotools.coverage.jaiext.enabled=true

Cheers
Andrea

Hi Andrea,

I can not update my GeoServer currently therefore the implementation you have mentioned is not possible for me.

There should be some way to define by SLD and layer config that one value should be transparent. Actually I had a setup which done exactly that, but I have no copy of the sld and layer config anymore.
