GNS Science offers processing and analysing expertise for a range of sensors and platforms.

  • High spatial resolution
  • Hyperspectral
  • Thermal
  • LiDAR
  • Syntehetic aperture RADAR

Analytical techniques include radiometirc and geometric correction, enhancements, classifications and multi-temporal analysis. Mapping is calibrated and validated using field survey data and other spatial data, and can be integrated using GIS.
