This produces a white image, meaning it is probably only reading 8 bits. If I add PROCESSING "SCALE=AUTO", then the values are not maxed out at 255, but vary based on the size of data I am requesting. So this won't work either because in my mapping software, as I request smaller and smaller patches, the elevation data is scaled really weird and is not consistent.<br>

Is there anything I am missing to get 16 bit USGS DEM data to be distributed via Mapserver?<br>

Your setup seems reasonable. Can you provide me an example of an output<br>
file produced by MapServer? I'd like to examine it to ensure it is being<br>
produced matching the output format declaration.<br>
