Hi, I'm having bad results trying serve elevation data from GMTED2010 geotifs as .bil. On the client side, the file I get is the right size, however only the low byte of the 16 bit word has any values. The high 8 bits are always zero. That has the effect of making all of my elevations appear to be between 0 and 255 meters. If I try to download the data as 32 bit tifs, it works fine. Unfortunately, my client app is looking for .bils. Here's the start of my map file. I'm using the MS4W latest released version. Any help would be appreciated! Thanks, James
