For for some REALLY astonishingly realistic terrain maps, buy Flight Simulator 2004 and get some of the incredibly DETAILED terrain add-on's for the USA, UK, Europe, Japan, etc.- With a graphics card capable of hi-rez display (256MB works nice) you can point the camera at the ground from 3-5000 feet and get excellent Air Photos and use them in Vue with bump maps. This is the same effect as seen in the sample Vue scene on the Vue 5 Infinite CD featuring UK countryside. Also, the clouds in FS 2004 are also surprisingly good and can be used in Vue on Alpha Planes. Great for when you need cloud-tops, weather-storm fronts, etc- as the FS 2004 software (and add-on packs) go to great lengths to simulate realistic weather conditions...
