Dear William, I tested the (privately) sent sample data and it worked. I suspect that you are previewing the data without specifing the correct style. Either you set your style as the default one or you explicitly call it using the style dropdown. If you don't specify your style as the default one the "raster" style will kick-in and it does very little that is: - select a band, usually number 1 - stretch to 256 bits
The experience you are describing is compatible with this situation. Let me know how it goes. Regards, Simone Giannecchini == GeoServer Professional Services from the experts!
