TerraSAR-X EEC Full Scenes (Sample Data)
Free geocoded TerraSAR-X sample data stacks in full resolution (EEC format)
Description
TerraSAR-X and TanDEM-X are two German Synthetic Aperture Radar (SAR) Earth observation satellites with the commercial distribution rights being owned by Airbus Defence and Space GmbH.
Their flexible acquisition modes (six different) and imaging characteristics benefit data collections from very-high-resolution (up to 0.25m) to wide-area-coverage. Due to the nature of SAR, the satellites operate independently of daylight and weather conditions resulting in an unrivalled reliability in terms of data collections.
Technical information
| Feature | Info |
|---|---|
| Archive date / refresh frequency | There are datasets available for Silicon Valley / Bay Area and New Delhi as multitemporal stacks. TerraSAR-X has got a revisit time of 11 days to the same point on Earth. |
| Frequency bands | X-Band |
| Resolution | Two Acquisition Modes available: 1. Staring SpotLight (ST): up to 0.25m resolution; scene size approx. 4 x 3.7km2 (); 2. StripMap (SM): up to 3m resolution; scene size 30 x 50km2. () Actual scene size depends on incidence angle |
| Processing level | EEC (Enhanced Ellipsoid Corrected) |
| Data format | EEC: The 16 bit GeoTiff format can in principle be displayed with any image processing software. Special care has to be taken upon histogram manipulation. Depending on the analysis purpose, different parts of the histogram may be used for enhancement. |

Use cases
Multi-resolution – Multi-scale – Multi-polarized Acquisition Modes – from extensive maritime coverage to image interpretation close to optical (commercially unique resolution). Precise Monitoring System (IMINT and Mapping, Maritime Monitoring, Change Detection).
EEC: The product allows a quick and highly accurate overlay with other spatial data. It is used for all kinds of mapping purposes that require a precise geocoding. Even Amplitude Change Detection can be performed, provided layover areas are excluded from the analysis.
