The Dem formats I have used tread the height as grid center.
Some DTED sources have the dted (height at center) and also
a file with the average heights. I only process the data with
the height at center.

Are you generating the height values between one cell and the next cell?
Or are you talking about smoothing out the joins between one tile of DEMs
and another. I do not do either of these - yet but I plan to do some work on the
latter.
