It is one of the biggest music festivals in Europe and, in 2018, saw about 180,000 people attend the event
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 21st and 22nd November 2016, natural disaster hit the French overseas territory of New Caledonia. Several days of exceptional rainfall caused deadly flooding and two devastating landslides in the Houailou district, 235km from the capital Noumea. In just one hour, the discharge of the Néaoua river rose from tens of cubic metres per second, to 600m3 per second, causing the worst flooding in living memory and scouring or silting up nearly 10% of the surface of the agricultural plain. Around a hundred landslides combined, forming mudslides in small catchment basins, engulfing ten homes, and leaving eight people missing.
Critical information over the affected area was urgently required in order to help first responders plan emergency response on the ground. Accurate and the freshest imagery possible was also immediately needed to further understand the impact of the event and assess the damage caused.
“Thanks to Airbus Defence and Space Pléiades constellation and our local partner INSIGHT, we could access rapid post-event imagery. In addition, the resolution and precision of the Pléiades data enabled us to fine-tune our analysis. The reactivity of the teams concerned, Airbus plus INSIGHT, meant that we obtained the information we needed in less than 48 hours!” Mr. Jean-Christophe Lefeuvre, Former Head of the Conservation International office in New Caledonia Géomatique.
SOLUTIONS AND RESULTS
Relying on Airbus’ satellite constellation’s high reactivity, the Pléiades satellites were tasked with the highest priority over the town of Houailou in order to collect two 50cm products of the affected area, with a minimum cloud cover and an acquisition angle compatible with the operational needs of the project. Promise kept, the images were delivered after the tasking activation.
Airbus Defence and Space reseller in the Pacific, INSIGHT, carried out automatic processing of the Pléiades data in order to extract and understand the changes which had taken place.
In order to qualify the field data more precisely the change detection solution, using Pléiades 50cm products, uses a number of information enhancement techniques:
– A co-registration phase that allows perfect superposition of the images used.
– A change detection phase, which involves three main steps:
1) The “Magnitude Difference” which is the conventional method for change detection, taking into account the time lapse between the two images and apparent changes in vegetation.
2) The Principal Component Analysis (PCA), which is used for more detailed characterization of the changes on the ground.
3) And the Subtractive method that enables further details to be determined. This method is, however, heavily influenced by shadows on the vegetation.
– Finally, the results were concatenated and vectorised for direct integration into the GIS of the Conservation International NGO.
All of these processing operations and quality control checks were made available to Conservation International by INSIGHT just 24 hours after Airbus Defence and Space delivered the source data.
Pascal Sawa, Mayor of Houailou said: “Thanks to the partnership with Conservation international, an independent NGO, and INSIGHT, a Caledonian service provider, the Town Hall received a certain amount of information and summary documents very rapidly. These documents analysed all the various data concerning the sector, providing extremely valuable information in terms of observation of the sequence of events and provided an accurate and reliable description of the phenomena involved. They offered numerous options for investigation directly linked to the search for those who were unaccounted for.”
- Clearer understanding of the impact of the rainfall on the ground and precise insights over the area affected by the disaster, due to accurate and reliable change detection based on Pléiades 50cm products.
- Rapid access to critical information thanks to Pléiades unrivalled responsiveness combined with INSIGHT’s reactivity.
- Precise information thanks to the excellent geometrical accuracy of Pléiades imagery and clearer assessment of the variability of the vegetation cover thanks to high quality Near-Infrared (NIR) products.
On 13 March 2017, Somali pirates hijacked the Aris 13 oil tanker along with its eight Sri-Lankan crew members, whilst transporting bunker oil from Djibouti to Mogadishu. Once on-board, the armed pirates cut off all the communication and positioning equipment including the Automatic Identification System (AIS) emitter, which regularly transmits the vessel’s identity, position and course. When the CSO Alliance (a maritime community countering maritime crime on a global scale) lost Aris 13’s AIS signal they needed immediate high-resolution imagery to identify the vessel’s location.
The high-resolution Pléiades sensor was charged, with the OneDay tasking option, to obtain high-priority satellite images within 24 hours.
SOLUTION & RESULTS
The high-resolution Pléiades sensor was charged, with the OneDay tasking option, to obtain high-priority satellite images within 24 hours. The first image was taken near the port of Alula, on the north coast of Puntland. The ship was expected there due to the European counter-piracy operation EU NAVFOR (Op Atalanta), which initially indicated that pirates had hijacked the vessel. However, it was not possible to identify Aris 13 in the image taken on the 15 March 2017. A new acquisition was tasked with OneDay to capture the north west of the Port of Abo, in which Aris 13 was visible the next day. The detailed image allowed clear identification of the tanker’s length, width, shape and technical characteristics, and the crane on the middle deck.
- Very simple and fast satellite tasking process and imagery delivery through the online GeoStore
- Satellite images saved time and cost, whilst providing timely visibility of the remote and dangerous area
- High-resolution imagery enabled clear remote identification
The same night that the images were delivered, the Puntland coastguards began negotiations with the pirates and the vessel was released.
On 16 April 2016, an earthquake measuring a 7.8 magnitude struck Ecuador. Among other cities, the coastal town of Pedernales, which was in close proximity to the epicentre, was severely impacted, with several houses and buildings destroyed. Following the event’s news, Airbus’ Pléiades satellite constellation was immediately tasked to collect the most up to date information of the situation.
The OneNow tasking option, especially designed to answer emergency needs, was urgently activated to acquire Pléiades images of the situation.
The GeoStore web portal was used to instantly access satellite resources: The OneNow tasking option, especially designed to answer emergency needs, was urgently activated to acquire Pléiades images of the situation. On the same day at 16:10pm, just after the tasking plan was updated, an automatic notification confirming the planned acquisition attempt and time was sent to the client.
Only two hours after, at 18:04 pm, the satellite passed over the area of interest, with the image becoming available at 22:13 pm. It took just 4 hours and 9 minutes from image acquisition to the delivery of the fully processed image, providing the customer with visibility of the area on the very same day the order was placed. Using the provided Pléiades’ very high-resolution images, the damage was clearly visible – facilitating detailed insights due to the 50cm products and enabling the planning of an appropriate emergency response.
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.
On November the 5th 2015, the Fundão mining dam in Brazil failed for an unknown reason, causing one of the most serious ecological disasters the country has ever seen. The dam, which is located 500km north of Rio de Janeiro, was holding toxic sludge and mineral waste from a nearby iron mine. More than 60 million cubic metres of mud was spilt when the dam failed and this volume of unexpected material resulted in the failure of a second dam located below, further exasperating the issue.
Bento Rodrigues, a village located just two kilometres from the dam, was ravaged by the mudslide, killing 13 people and leaving more than 50 people injured. The toxic mudslide eventually joined the second largest river in Brazil, the Rio Doce, and then the ocean, killing thousands of fish and depriving half a million of people clean drinking water.
How do we respond?
When an unexpected disaster, such as this occurs, authorities need immediate visibility of the situation on the ground to enable an appropriate response to be planned and executed. The International Charter ‘Space and Major Disasters’ aims at providing precisely that. It is a unique, global collective of 16 space agencies, initiated in July 1999 by the European (ESA) and French (CNES) space agencies. Airbus DS Intelligence is one of its historical partners. It responds to the Charter objectives in using satellites to rapidly collect and disseminate imagery, to provide local and national authorities with the intelligence they require to plan an effective emergency response and mitigate the humanitarian impact of a disaster.
Each member space agency has committed resources to The International Charter, giving authorised users access to a unique pool of know-how and satellites resources, which can be tasked through the Charter’s dedicated online portal, 24/7, at no cost for the user.
The Pléiades constellation was selected due to its ability to acquire and deliver imagery in near real-time – therefore offering the most suitable solution for fast and useful results.
On the 8th of November 2015, The International Charter was triggered by INPE (the Brazilian Space Agency), on behalf of CENAD (Brazilian National Risk and Disaster Management Agency). Among several optical satellites requested by the International Charter, Airbus tasked the very high-resolution Pléiades satellite constellation, using its unique OneNow option, to retrieve images of the area surrounding the Fundão mining dam, in order to identify the extent of the disaster and help the response activity. The Pléiades constellation was selected due to its ability to acquire and deliver imagery in near real-time – therefore offering the most suitable solution for fast and useful results.
Once tasked, Pléiades faced a challenge due to heavy cloud cover over the area of interest. Thanks to OneNow option, Airbus delivers three acquisitions in the shortest timeframe and in case of difficult weather conditions, the activated satellite constellation insists in collecting the area until successful images are obtained: extra top-priority acquisitions are made to provide urgently a clear view of the situation: the first Pléiades image of the dam was thus acquired on the 11th November. 6 mapping products, based on several Pléiades images acquired in two days, were processed by CENAD and helped them to develop an appropriate response to the disaster.
On the 25th April 2017, the first new generation Airbus A400M airlifter, destined for the Spanish Air Force, arrived at Santa Lucía Air Base in Mexico, ready to be displayed at the FAMEX 2017 exhibition. The Airbus Intelligence team was tasked with capturing an image of the event from the air, using Airbus’ advanced earth orbiting satellite constellation. With only one day to secure the required imagery before the aircraft returns to its home base in Zaragoza, Spain, the Airbus team needed to act fast and task a high- resolution sensor capable of capturing the event in fine detail.
The team used One Tasking OneDay option, which enables customers to specify the exact day on which an image needs to be acquired, as well as the resolution.
To meet their objective, the team used One Tasking OneDay option, which enables customers to specify the exact day on which an image needs to be acquired, as well as the resolution. The tasking was booked using the intuitive online tasking system, GeoStore, which can be accessed by anyone with a GeoStore log in. Pléiades was identified as the best satellite for this task, due to the constellation’s high resolution 50cm-product. The constellation consists of two identical satellites, orbiting 180 degrees apart, which increases the revisit rate and capability to capture images on the daily basis.
On the event day – as soon as the first Pléiades satellite passed over Santa Lucía, the area was collected; From then on, the process is really fast: about 2 hours after collection, an acquisition notification is sent to the customer; at the same time, the image automatically goes into our production system to be delivered and ready to be used approximately 30 minutes after.
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.
Sergio Samarelli, Planetek CTO
“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.

In Nigeria – one of only three polio-endemic countries left in the world – 122 new polio cases were identified in 2012. Only prevention can help make a lasting difference. To achieve full eradication of this disease, an exhaustive vaccination programme needed to be implemented across the entire country within a very short timeframe. To reach every child, vaccination campaigns can benefit from using satellite imagery. Indeed, mapping all types of settlements using satellite imagery can help foster more efficient deployment of health professionals and ensure no village is missed.
That was the challenge undertaken by GIM, a Belgian company specialised in processing VHR imagery for urban applications, in partnership with eHealth Africa, an NGO that has their headquarters in Nigeria and works across West Africa. This mapping effort took place as part of the framework of the Global Polio Eradication Initiative, with active participation from the World Health Organisation and UNICEF together with the Nigerian local government authorities.
To achieve its ambitious goal, GIM leveraged their partnership with Airbus Defence and Space to collect spatial data over 225,000 sq.km in Nigeria. The objective was to create a fresh and accurate map of all human infrastructures in order to have a comprehensive view of places and people to target. Within the project’s defined timeframe fresh imagery needed to be acquired to develop the map and implement GIM’s ambitious mission.
Within the record timeframe of 30 days, an immense area of 50,000 sq.km was acquired.
SOLUTION & RESULTS
1st stage: fresh and highly detailed data
From single huts to large cities, including roads and rivers, all features had to be visible on the end-users’ map. OnePlan was identified as the most appropriate One Tasking option to acquire high-resolution images using the 50cm resolution Pléiades sensor to cover the extensive area within the project’s defined timescale. One challenge was to meet GIM’s need for extremely detailed, but also fresh data to make a most accurate assessment.
In September 2013, Pléiades satellites were tasked over the Nigerian region. Within the record timeframe of 30 days, an immense area of 50,000 sq.km was acquired. This collection was then further extended to meet GIM requirements.
2nd stage: An Updated map, perfectly matching GIM’s needs
GIM leveraged its in-depth expertise in Object-Based Image Analysis (OBIA) to process the orthorectified and pansharpened imagery. This data was processed in record time and the end-user, eHealth Africa, provided with a constant flow of information supporting the vast immunisation campaign.
The spatial imagery offered very high-quality visual information to establish an updated map covering an area of 100,000 sq.km depicting 500,000 buildings, 20,000 villages, 1,500 cities and many roads, tracks, lakes and rivers; contributing to not missing a single child at risk of catching polio.
3rd stage: Speculative tasking for optimising local interventions
The World Health Organisation (WHO) declares a country cleared of the disease only after three full years with absolutely no trace of the virus, whether among the population or in the environment.
Airbus Defence and Space therefore launched speculative acquisition over Northern Nigeria, where the virus used to be active, and Pléiades has covered 178,000 sq.km over this region. Local organisations are now able to optimise their physical interventions by using this fresh data as soon as needed and with a high standard of support.
- OnePlan increased efficiency of the vaccination planning: Employing Pléiades through OnePlan facilitated the reliable delivery of the right qualified coverage within the specified timeframe, which perfectly matching project milestones and was completed on time and on quality.
- Systematic extraction of all human features: Pléiades 50 cm mapping product is an efficient solution to create comprehensive mapping.
- Guaranteed of a genuine partnership: the collection plan was initiated hand in hand with GIM from the beginning in order to determine the level of priorities fully consistent with the vaccination planning and roll out. The speculative acquisition also anticipates – and guarantees immediate availability of the updated basemap whenever needed – and at a reduced cost.
By contributing to map all types of settlements in record time, the use of Pléiades satellites can help create a map and thus foster a more efficient organisation of massive deployments of resources on the ground.
AT A GLANCE
Optimise polio vaccination campaigns by collecting very-high-resolution images across an entire country in a short time.
SOLUTION & RESULTS:
Rapid delivery of the freshest basemap information to produce accurate maps.
Increased efficiency of the vaccination planning and great support to polio eradication.
