Radar data represent a specific data that are acquired in the microwave part of electromagnetic spectrum. Owing to that the radar images can be acquired in any weather, in a day or night. Presently, the radar data with spatial resolution tens of meters are available. In the very near future a 1m resolution will be a reality. Radar data conveniently complement conventional optical data especially when climatic and meteorological conditions don’t enable getting the optical ones.

The typical applications include:
  • Floods and floods zones mapping
  • Geomorphologic mapping
  • Monitoring of seismological movements and landslides
  • Ship monitoring, detection of sea and ocean pollution
  • Glaciers mapping and monitoring
  • Tropical forests mapping and monitoring
  • DEM generation
