| Data product | Data returned | Details |
|---|---|---|
| TH-01 - satellite image data | Four raster channels for DGP, one raster channel for GFB, one raster channel for SXZ. | GDB retrieves image channels for multispectral data. |
| Product annotation data | One text segment for product information. | GDB generates a text segment for product information. |
| RPC data | Rational Polynomial Coefficients (RPC) segment. | The Level 1B products and up are delivered with associated RPC values for each band. The RPC values can be used for advanced image processing. GDB retrieves this information as an RPC segment for each band. |
| 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. |
