Maarten,
GDAL/MapServer supports the DTED format. DTED files; however, do not
normally have the .hgt extension. This often is used for SRTM data
in "raw" format.

global mapper to convert it to geotiff. The geoTiff is 1201x1201 and
has three bands:
Band 1 Block=1201x1 Type=Byte, ColorInterp=Red
Band 2 Block=1201x1 Type=Byte, ColorInterp=Green
Band 3 Block=1201x1 Type=Byte, ColorInterp=Blue
It would appear that this translation with global mapper has damaged
the image data - converting it to 8bit and apparently into RGB mode
as well. Either skip this step and work directly from your DTED files
(if they are really dted) or figure out a more appropriate way to do
the translation.
Best regards
