This would be the next step for flight simulators, which while remarkable still require handmade assets for accurate details.

MSFS 2024 already does photogrammetry from satellite photos. However, it builds triangle geometry much like is done from aerial photography, because gaussian splats are not suitable for games; you can't build collision geometry from a gaussian splat for example.

afaik msfs uses partially automatically generated 3d assets (from Bing Maps?) from aerial/satellite imagery.
