VirtualPlanetBuilder is a terrain database creation tool that can read a wide range of geospatial imagery and elevation data and scales from small-area terrain databases to massive whole-planet paged databases. These databases can be uploaded to the Internet to provide online GoogleEarth-style roaming of whole-planet databases, or kept on local disks for high-speed access for professional flight simulator applications.
