TerraSAR-X Orthorectified Images
The Basic TerraSAR-X EEC product is orthorectified by applying readily available DEMs of the respective area. The quality of these DEMs may range from DTED Level 0 (usually from digital maps) up to DTED Level 2 (e.g. from the Shuttle Radar Topography Mission SRTM).
In an ORISAR, the geometric localization accuracy is enhanced by applying a more precise DEM (if obtainable or delivered by the client) as an essential input for an improved orthorectification process.
The product characteristics of a TerraSAR-X ORISAR are:
- Multilook detected
- WGS84 with standard projections UTM or UPS
- Choice of radiometric representation
- Radar brightness (beta naught)
- Radiometric calibration (sigma naught)
- Radiometric normalisation (gamma naught) - Information on local incidence angle, layover and shadow areas provided
- Application of different SAR filters (GAMMA MAP, Lee, etc)
