I want to get DTED data (elevation) between two points (on a line). Is there any built-in function for this purpose or I should implement it on my own?

What I want is similar to Linear Line of Sight (LLOS), but it should be on a direct line. I want to check if there is collision between two points or not.

Thank you

Sincerely

What did you end up doing? Your own interpolation, or did you find a package? –  kmort May 10 '13 at 14:42
