| Video Games include travel through race courses (Crash and Burn) |
| or through ÒMystical WorldsÓ as in Donkey Kong or for the new generation of PC games such as MYST |
| Other PC edutainment systems such as Oregon Trail and Carmen San Diego provide Òadventure/knowledgeÓ filled journeys through sort of the real world |
| NASA, USGS and other sources (such as Russia) provide digital terrain data which can be used to provide totally realistic Òflight simulationsÓ |
| Current widely available 3D data has 10 to 30 meter resolution but even now, Synthetic aperture radar sensors are being tested which can be flown in a plane and give horizontal and vertical resolution of around 1 meter. |
| The software to implement this is called a Geographical Information System (GIS) |
