| QuickBird satellite image data | Four channels for multispectral data, one channel for panchromatic data | GDB retrieves four image channels for multispectral data, one channel for panchromatic data |
| Ephemeris data | One orbit segment | GDB imports ephemeris data as an orbit segment. This segment contains information about the satellite position, satellite attitude, IFOV, projection, sensor, and orbit. |
| RPC data | One binary segment | GDB imports a rational function model as a binary segment (if the data product provides this information) |
