Terracopter is a real-time fly-through 3D viewer for digital map data. If you have map data that you would like to view in a more realistic way than is possible in traditional 2D applications, Terracopter might be useful for you.
3D software performance used to be an issue. With Terracopter that is no longer the case. Real-time 3D visualization is an obvious dream for anyone using complex and large data-sets consisting of information types such as terrain height, land usage, building geometries, aerial photographs, coverage maps and network infrastructure data.
