TerraSAR-X

Very high resolution 25 cm SAR satellite imagery, acquired worldwide with a revisit rate of 2 to 11 days.


Overview

TerraSAR-X imagery is acquired by two high resolution radar satellites (TerraSAR-X and TanDEM-X) every 11 days anywhere on the globe. See more on the marketplace.

This collection provides the following processing levels:

  • Single Look Slant Range Complex (SSC)
  • Multi Look Ground Range Detected (MGD)
  • Geocoded Ellipsoid Corrected (GEC)
  • Enhanced Ellipsoid Corrected (EEC)
