A few more bits on this one. Here are two examples of course listings which I mentioned earlier:
US Coast Guard Academy course catalog 1975/76:
"Nautical Science I: An introduction to the rules of the nautical road, relative motion, and terrestrial navigation. Specialized concepts of geography, familiarization with piloting techniques."
US Naval Academy course catalog 1980/81:
"Navigation I (2-2-3). Terrestrial navigation including piloting and navigation systems for surface navigation, basic meterology and Inland Rules of the Nautical Road."
Considering the folks I spoke to say that "everybody uses this expression", I was surprised to find not a single book entitled "terrestrial navigation" except for two exam manuals for USCG licenses (one of the books is not yet published). See the attached search from amazon. That seems to confirm that, at least in English-language usage, this term is primarily emerging from the US Coast Guard licensing process vocabulary, and it is not widespread.
