DTED is a regular grid format defination for terrain
elevations. Basically 1201 points in a single degree
latitude and longitude. The format is described at
http://www.nima.mil/publications/specs/printed/DTED/DTED_1-2
.html though it is pretty dry reading.... hehe
To convert from flight to DTED would be pretty straight
forward **IF** the flight file was originally taken from
DTED, you should be able to take the vertices and convert
them back to the DTED posts. however, if the grid has been
reduced via delauny you'd have to re-gridify (do
programmer's make up these words?) the data before writing
it back out. I read and write DTED files here, but I am
afraid I do not have code for reading and writing flight
format....
