Just an addition in case the comments disappear:
As Woj has posted:
you fly around and your nav system simulates the canyon
This is why the terrain matches the real target - but not in real life - it matches it on his MFD (multifunctionaldisplay) (NAV)- which is switched to moving map display with route and waypoints on it (NAV system simulating the canyon), and the screen in the class room following him.
What the camera shows outside the cockpit is more for entertainment and Mavericks situational awareness.
with modern technology, you can often get a detailed terrain map of the target location. Quite often this is used with terrain following/mapping/guidance and gps type tech - and is used in weapons such as cruise missiles in matching the actual terrain and waypoints to the ones prepared for them in their programming. I have no doubt that same kind of information can be used in preparing for manned missions too.
"LVC – live, virtual and constructive. The live aspect is the military members actually flying in their operational airplanes, driving in their operational truck or vehicle on the ground, remotely piloted aircraft – they’re using their operational equipment. But we’re able to tie that to a virtual environment which is a simulation of that operational equipment. And the constructive environment which is computer generated models and entities that allow us to create realistic threats, realistic bad guys and behaviors that our folks can actually go after.”
the data is generated from intel yes, then looks like Tom has a predefined route planned that matches with the CGI intel terrain map shown in the class room. His actual flight path - that he is flying - is not in the same terrain in real life as seen in the intel CGI map - you can see that when he gets on target, drops his munitions and then goes for his high-G pull out - in the class it is there, in real life he is just flying no mountains around him.
the pit is generated from intel data, fed into Toms MFD (multifunctional display) and has a moving map read-out - the map moves with you as you fly. So Tom isnt flying so much with his eyes but using that intel instead, matching his route with that of the intel, not the real life world around him (within reason of course) - what they have in the classroom is only the intel map terrain, so that is what you see, what Tom is following, but the movie camera is showing everything outside as well.
On commercially available multi function displays you might see it as
Synthetic Vision is just that — a completely fake, albeit accurate visualization of the flight environment created through sensor fusion and 3D rendering. SynVis can only show you where you are in relation to things that it knows about within its databases or that are fed to it from an ADS-B or other traffic system.
quite common these days, and can be merged with realtime camera feeds too, known as enhanced vision system
This is the commercial variant if you like:
Real flight photo, the left MFD (primary flight display) shows the recreated synthetic CGI topographical terrain environment overlaid with flight data, the nav system if you like.
Tom would have similar with his flight data programmed in.
