Tromso Satellite Station has processed Synthetic Aperture Radar (SAR) images from ERS-1, JERS-1, and RADARSAT satellites since 1993. The archive includes full and low-resolution images covering 100x100 km and 75x75 km areas, produced within 8 to 20 minutes of acquisition. The data was made available through the Norwegian national ERS-1 programme and agreements with ESA and NASDA.
Use Cases
- Ice monitoring based on near real-time ERS-1 SAR data.
- Ship detection based on full-resolution SAR imagery.
- Oil spill detection based on calibrated low-resolution SAR images.
- Weather and wave forecasting based on SAR data products.
- Agricultural land use analysis based on applications like autumn ploughing detection.
Strengths
- Images are processed and available for distribution within 8 minutes (ERS-1) to 20 minutes (JERS-1) after acquisition.
- Covers specific areas of 100x100 km for ERS-1 and 75x75 km for JERS-1.
- Offers multiple product types: full resolution, low resolution, and calibrated low-resolution images.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
