Hi, Have you checked the histograms? It is not unusual that the histogram is badly biased to the black end and image just shows black on the screen. If this is the case then you will need to push the image through a histogram stretch somehow, either by preprocessing or by letting Geoserver to do it. Unfortunataly I have no ready recipes at hand for either.
