TerraSAR-X/TanDEM-X full archive and new tasking products can be acquired in six image modes with flexible resolutions from 0.25 m to 40 m. The dataset includes products like Staring SpotLight, High Resolution SpotLight, SpotLight, StripMap, ScanSAR, and Wide ScanSAR, each with specific scene sizes and processing levels. Products are provided by ESA and cover worldwide spatial coverage.
Use Cases
- Generate high-resolution digital elevation models based on interferometric processing packages (InSAR-ST, InSAR-HS, etc.)
- Monitor maritime activity and coastal changes based on the Maritime Monitoring package requiring scenes with at least 75% water area
- Analyze land surface changes over time based on the availability of multiple image modes (StripMap, ScanSAR) with resolutions up to 3 m and 18 m
- Create terrain-corrected maps for infrastructure planning based on Enhanced Ellipsoid Corrected (EEC) processing using a DEM
Strengths
- Offers six distinct image modes (Staring SpotLight, High Resolution SpotLight, SpotLight, StripMap, ScanSAR, Wide ScanSAR) with resolutions ranging from 0.25 m to 40 m
- Provides multiple processing levels (SSC, MGD, GEC, EEC) in formats including GeoTiff and COSAR binary
- Includes specialized packages for interferometry and maritime monitoring with specific ordering requirements
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download
- Column-level documentation is absent; field semantics must be inferred after download
