Perhaps I’m missing something here, but wouldn’t a GPS with AGL output be the simplest solution?

Yes, but its not that simple.

That will need a terrainmap, which is freely available, no worries, and it needs a basic GPS reciever - 50bucks, no problem, then it needs some software - easily scriptable in Perl or Python, but the problem is persuading some open-source geek that it would be a cool thing to do. Even the little computing platform to run it on is available dead-cheaply, and draws only an amp or so at 12VDC.

eah and besides, the system will only be as good as the maps are AND as good as the GPS signal is (degradation etc)
