Hi Eric, The reason that you are getting only a red band in your output file is because DEM data has only one band. Therefore you should use the greyscale option to compress this data. Also, DEM data is not usually compressed to ECW as the pixel values will be resampled to 0-255.
Please contact me offline should you have any questions.

I've run the ECW compressor (free version) on an individual tile, selecting the HDR file, and the results are pretty poor. When choosing the RGB option in the GUI, the output shows only red, as if the other bands were ignored. I would like to use compressed GLOBE tiles within ESRI's MapObjects. Any help would be appreciated!
