Hellfest is a French rock music festival held annually in Clisson, Loire-Atlantique. It is one of the biggest music festivals in Europe and, in 2018, saw about 180,000 people attend the event.
Airbus’ Pléiades satellite resource was tasked specifically for June 23rd to collect the spectacle of the festival. The Pléiades satellites constellation acquired 50cm products of the event, showing the sheer scale of the event, including the crowds gathered, the parking lots, the enormous tent villages and even the long lines of people waiting in front of small kiosks.
Airbus’ OneDay tasking option fully relies on the true daily revisit of Pléiades satellites constellation that allows Airbus customers to task the satellites on a specific day and get their image exactly when and where needed in record time.
On Saturday 19th May 2018, we acquired the Royal Wedding procession route through Windsor, UK. Over 100,000 people from across the world lined the procession route and gathering crowds can be seen in this acquisition by Pléiades, taken at 11.32am local time. Following the ceremony, a horse-drawn carriage took Prince Harry and Meghan Markle from St George’s Chapel in Windsor Castle through the town and along the tree-lined Long Walk in Windsor Great Park.
Over 100,000 people from across the world lined the procession route and gathering crowds can be seen in this acquisition by Pléiades, taken at 11.32am local time.
Within hours of capture, and following the successful download, processing, and delivery, this acquisition was circulated with international Media. Pléiades is an optical satellite constellation offering a true daily revisit capability that allows our customers to precisely request an acquisition on a specific date. At 50cm resolution, the constellation was the perfect solution to handle the OneDay tasking request and deliver a beautiful image of this historic Royal event.
A magnitude 6.2 earthquake struck the centre of the Italian peninsular on 24th August. The mountain village of Pescara del Tronto was almost completely destroyed and the town of Amatrice was turned into a pile of rubble in just a few seconds.
Detailed images of the area, and in particular the two towns most affected, urgently needed aid and the appropriate emergency response planning on the ground. The extra-high tasking priority from OneNow option, utilising the high-resolution Pléiades satellites, was the right solution to obtain detailed coverage quickly. The satellite was quickly programmed using GeoStore.
By comparing the captured images of the situation with a Pléiades archive image of 13th July 2015, the impact of the earthquake on buildings and the roads network was immediately visible on the image captured on 25th August 2016, the day after the disaster.
The OneNow tasking option enables information from Pléiades and SPOT6/7 satellite images to be obtained less than 24 hours after the programming request was made on GeoStore (or directly through the customer’s usual Airbus contact). To obtain most useful results, up to three forced satellite acquisitions are proposed to provide coverage of the area of interest at the soonest. If weather conditions are difficult, additional attempts are proposed, until cloud-free coverage is obtained. For the earthquake in Italy, OneNow programming was initiated for three Pléiades acquisitions on 25th, 26th and 27th August 2016. However, it was possible to already identify the extent of the damage on the first acquisition.
In May 2016, Serbia experienced some of its heaviest rainfall in a generation. Over the course of just three days, the equivalent of three months’ worth of rain fell, causing devastating floods and landslides. 51 people lost their lives and over 30,000 people had to be evacuated, with extensive damage caused to homes and infrastructure.
One significant challenge for responders was the lack of information about the landslides and that the total number of landslides was understated, which resulted in an inaccurate ‘national landslide inventory’. These inventories typically provide valuable information about the location and severity of a landslide, which then allows for risks to be assessed and for the planning of an appropriate response. In Serbia, there was no national landslide inventory available prior to the disaster and no institutional consensus between governmental and scientific stakeholders responsible for landslides. To facilitate a more systematic response, the BEWARE project commenced, which fused landslide data acquired from field data and satellite imagery. The project’s objective was to assess the damage and to compare it with previous events to assess and prevent risks more efficiently, whilst preparing the local population.
SOLUTION & RESULT
The BEWARE team (Beyond Landslide Awareness) needed detailed satellite based intelligence to produce an accurate assessment of the situation on the ground. One Tasking’s OneNow product was selected as the right imaging product for job, offering instant tasking of a satellite with a high priority. In a first project stage, different scales were used for field mapping and satellite analysis. Over pilot areas, high-resolution Pléiades, as well as the wide-swath SPOT6 satellite were used to acquire images of the area just after the disaster. Based on Pléiades’ high-resolution imagery, an effective method for the data collection was developed, which was validated through field surveys in specific areas. The results were then extrapolated with SPOT6 images, which covers a wider area than the Pléiades images. In a next stage vulnerable areas were identified, which supported the preparation of the local population and risk management to prevent future disasters, where possible.
- Pléiades and SPOT6 images provided a quick and clear picture of the impacted areas
- The remote satellite imagery acquisition lowered the project’s overall expenses and time, in contrast to field mapping costs
- The multi-scale approach using high-resolution Pléiades and wide- swath SPOT images lowered the overall expenses
- The provided data enabled satellite data pooling and sharing, which will be used to prepare municipalities when facing future landslides and to prepare civil agencies, as well as emergency services to react quicker
Etna, Europe’s tallest active volcano dramatically erupted in March 2017, causing ‘phreatic explosions’, which occur when molten lava touches snow. These explosive reactions caused hot stones and steam to be sent into the air at speed, injuring several people with some needing to be evacuated by rescue teams.
Timely coverage of Etna’s eruption
Just before the event, with the eruption expected within hours, Airbus’ Pléiades constellation was tasked to retrieve high-resolution satellite images of the volcano on the day of the eruption; indeed, 50cm products are perfectly suitable to understand the extent of the area affected and perform an impact analysis. Tasked just one day before the eruption, Airbus’ OneNow option, specifically designed to respond to emergency needs, was identified as the most appropriate solution; The Pléiades satellite resource was booked for a high priority acquisition over the volcano on the 18th of March.
Shortly after acquisition, the acquired images were immediately delivered to the customer. On the images, the lava flow and smoke could be easily identified on the collected images providing the client with most suitable information to assess the situation on the ground.
Saipem S.p.A, an Italian oil and gas industry contractor, subsidiary of Italian energy company ENI, had planned to design and construct pipelines in the Caspian Sea. However, this type of work entails intensive dredging, which involves moving underwater sediments from one place to another and thus disturbing water quality.
Traditional water quality monitoring techniques, such as sampling at sea and laboratory analysis, present logistical and operational inconveniences as well as long processing times. This is often incompatible with a company’s need to obtain real-time information. In addition, field observations and measurements, while frequent, are not able to provide a complete and exhaustive spatial answer to describe all the phenomena in progress. Solutions to monitor water quality and compliance – also known as sea turbidity – rely more and more on satellite imagery.
Planetek Italia, a company specialising in geospatial value-added products, deliver water quality reports to Saipem. They contacted Airbus Defence and Space as they needed to get very detailed information, at random and unforeseeable times, in the shortest timeframe.

“We are proud to be able to offer near-real-time services thanks to the fast and reliable tasking service offered by the Airbus Defence and Space satellite constellation. The availability of these capabilities really boosts the opportunities for value-added service providers to offer real solutions to customer needs.”
SOLUTION & RESULTS
Airbus Defence and Space had to guarantee daily and flexible access to imagery. Pléiades OneDay tasking option was the ideal and cost-effective solution. Planetek placed 5 OneDay orders through GeoStore. Thanks to a fully automatic process, all the images were delivered in just 2.5 hours after acquisition!
Planetek quickly extracted the information needed from the imagery and delivered an analysis report to the end-user, Saipem. The result was a quantitative and spatial definition of the dispersion of sediments during dredging operations. Saipem was thus able to receive near-real-time overviews of the dredging impact during the execution of their work.
The satellite imagery based information was used by the company to report their compliance with environmental norms to authorities as well as to increase their efficiency in monitoring all ongoing events during the execution of works.
- Efficient Time Management: 24/7 OneDay Tasking service availability through GeoStore, Pléiades guaranteed acquisitions and rapid deliveries.
- High Accuracy: Saipem benefited from reliable water quality monitoring thanks to Pléiades high resolution, enabling detailed dredging activity assessment by Planetek.
- Cost-Efficient: OneDay tasking option enabling access to information without sending people on site.
