Data Products
| Data Product | Description | Geometric Processing Level | Bit Depth | File Format |
|---|---|---|---|---|
| SLC | Both amplitude and phase of the SAR signal available. Range-compressed and focused SAR image in slant-range geometry. Georeferenced using orbit data and Range-Doppler projected. Suitable for SAR experts who are working on monitoring studies that require the analysis of phase information (e.g. coherence analysis). | Primary | 16 bits | COG + JSON |
| GEC | Only amplitude information available. Range-compressed, detected, focused and multi-looked SAR image with enhanced radiometric resolution. Resampled and projected onto a WGS84 ellipsoid with average scene center height. UTM and UPS projections. | Ortho | 32 bits | COG + JSON |
| GEO | Only amplitude information available. Range-compressed, detected, focused and multi-looked SAR image with enhanced radiometric resolution. Terrain-height corrected using a high-resolution Digital Elevation Model (DEM). UTM and UPS projections. | Ortho | 32 bits | COG + JSON |
| SICD | Both amplitude and phase of the SAR signal available. Range-compressed and focused SAR image in slant-range geometry. Sensor independent format. | Primary | 16 bits | NITF (SICD) |
