Change detection

Many different temporal changes can be detected by satellite, including urban development, construction, erosion, deposition and disaster impacts. In this example, changes in vegetation health due to climate extremes and deforestation needed to be determined on the island of Cyprus.

Our algorithms allowed us to detect the changes in vegetation in terms of NDVI across large areas and over long time periods from satellite images. We also detected the extent of areas affected by the devastating forest fires of July 2021.


  • Large scale, remote monitoring of vegetation health. 

  • The extent of damage from recent forest fires was also determined.

  • Other changes can be detected including urbanisation, construction, erosion and deposition.
