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:
