[TowerTalk] Fwd: Some more background on HFTA terrain data

[Pete Smith]

In the light of the discussion about terrain modeling, I thought the 
following from N6BV would be of interest.  There's a fair bit of common 
material in the two papers, but the second is particularly informative on 
the differences between DEMs and the seamless NEDs.
