Altitude-based Fog of War Reveal

I would like to see a reward in the map functionality for attaining extreme altitude and a far wider swath of exposure for the glider during flight. Anything you can physically see should be revealed, in terms of overall terrain. This is basically how reconnaissance works. Unless specific items are extremely visible (such as the towers), they shouldn't be added to the map until you FIND them on foot, but peeling back the fog-of-war to show the topographical map should be easier to do.
