The Airbus’ constellation’s daily revisit capability and high-resolution satellites were used to track damage caused over time and organise recovery operations.
In January 2017, Chile declared the ‘state of emergency’, when the South American country experienced the worst wildfires in its history. More than 100 fires raged through central and southern Chile, spreading uncontrollably across the region, endangering lives and leading to the evacuation of thousands of local people. Strong winds made the situation even more severe – access to the latest imagery-based intelligence, detailing all potentially affected areas and the current situation on the ground, was essential.
The solution and result
To support the Chilean government’s response, Airbus immediately activated the wide swath SPOT 6/7 satellite constellation using its OneNow tasking option. In a first instance, near real-time imagery were acquired over the huge area of 233,623 km2. In a second stage the acquisition focused on some priority regions. SPOT 6/7 images enabled the identification and location of specific fires; the images were used to understand where further evacuations were necessary and to plan an effective response strategy.
Following the initial acquisition, the Airbus’ constellation’s daily revisit capability and high-resolution satellites were used to track damage caused over time and organise recovery operations. OneNow tasking option takes up to three top-priority collections and rush deliveries on a daily basis and in the shortest possible timeframe. This means as soon as the satellite passes the area of interest, an image is immediately acquired and delivered. If cloud cover is still an issue after the first three attempts, Airbus’ constellation continues acquiring images of the area with the highest collection priority to provide the client with the best reactivity and freshest information. This flexibility and commitment to providing useful results helped Chile’s regional governments to plan their emergency response with the most accurate information, protecting the population and reducing the long-term environmental impact from the incident.
