I've not heard of DEM data before, however after reading a little
about it ( "Digital Elevation Model" ) - I don't see why you couldn't
use it. You'd have to convert the data into one of the following
supported formats and it'll work seeing as how it's a regularly spaced

unsigned char ( 8-bit )
short ( 16-bit signed )
float ( 32-bit )
double ( 64-bit )

I'm guessing you'd preallocate an array using the width and height and
then fill in the height value cells as you read the file.
