Using two SENTINEL-1A radar images acquired on March 27 and April 20, 2016, and differential interferometry (DInSAR), the Effigis Earth Observation team measured the ground displacement that took place following this earthquake.
High-resolution satellite images acquired in urgent mode can be used to plan and manage interventions during a natural disaster (forest fire, earthquake, flood).
Using Landsat 7 and 8 satellite images, we see the extent of the natural disaster that has been raging since May 1, 2016 at Fort McMurray (Alberta).
Landsat-7 and 8 satellite images allow to see the extent of this natural disaster.
It’s true that it does not easily spring to mind that the images captured by Earth observation satellites, nowadays with submetric spatial resolution at best, can produce displacement measurements with a precision measured in centimetres or millimetres, as the experts claim. But what exactly does this involve?
