Dear David, Steve, Ben, etc. I am working with MapServer-WCS. I still have problems defining the correct output formats. Input to most of our WCS are 8bit Geotiffs. The MapServer WCS-output is either tiff, png or jpeg with 24bit or Png;mode=8bit with 8 bit (if no output format is defined). The png;mode=8bit-format changes the imagecolours, so it isn't really useful. I can't get a colored 8bit Geotiff as output (a 8bit-definition always results in greyscale images). I tried different output format-definitions, none of them worked. I can define a palette for the png-format, but unfortunately not for any other format. For our WCS it is important that the output-data looks the same like the input-data. It seems that at the moment MapServer can't just pass the input-data through... This might be a GDAL issue...
So if you find a way to define your wished output-format, please share it, maybe it helps me, too. Maybe anybody else has an idea?
