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 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.
Oil represents one of Libya’s main sources of export revenue and with an estimated 48 billion accessible barrels, the volatile nation has one of Africa’s largest reserves. Since 2011, Libya’s oil industry has been hit by frequent attacks, causing oil production to shrink to less than a quarter of its pre-uprising levels.
Libya’s largest oil terminal, which is also home to a refinery and a number of crude oil storage tanks, is located near the port of Ras Lanuf. In 2016, a series of terrorist attacks set several of the tanks on fire, causing them to burn uncontrollably for several days. Pipelines in the area were also attacked during that time, with oil workers struggling to isolate pipelines and contain the damage. The area, which is located 220 kilometres southwest of Banghazi and 200 kilometres southeast of Surton, needed to be regularly monitored to provide stakeholders with accurate updates of the situation on the ground and to enable an appropriate response to be planned.
The area immediately around the Ras Lanuf Oil Refinery was of particular interest and an accurate level of awareness was essential.To achieve this level of up-to-date visibility, the decision was taken to use Airbus’ very high-resolution Pléiades satellites constellation, which can be flexibly updated in accordance with a client’s specific requirements and provides decision-makers with the required detail, without incurring unnecessary risk or costs associated with in-field surveying.
As regular monitoring of the area was essential, the OneSeries option was selected as the most appropriate service from the One Tasking portfolio.
OneSeries allows for regular tasking of Airbus’ satellites, at the customer’s required frequency, enabling constant monitoring of a specific location or area, with cloud coverage guaranteed to represent less than 10% of the image. As requested for this project, the images were captured and delivered every two weeks.
THE SOLUTION & RESULT
The first image was captured on the 16th of January 2016. It shows dark grey and black patches – oil leaks saturating the desert’s sandy ground. Visually, the oil leaks are in stark contrast to the light brown colour of the desert which surrounds the oil refinery. The image also allows the client to clearly identify burnt out tanks. An intact tank, as visible in the North, has a white roof and white side-walls. In contrast, the damaged tanks are black on the image. Some of the oil tanks don’t even have visible side-walls anymore and they appear to have been torn apart due to explosions or destroyed in the fire, with oil seeping into the sandy ground around them.
Another image taken on the 30th of January 2016 shows that the situation on the ground has worsened further. A fire with black smoke and a new oil leak are visible in the North, whilst further tanks in the storage facility’s centre appear to be damaged. Near infra-red views show the fire in great detail, sufficient enough to understand the real situation and to inform the emergency response.
Images taken on the 13th of February show that the situation on the ground now is under control – the leaks haven’t worsened and there is no smoke or fire visible anymore.
Images taken on the 29th of February show that cleaning work of the facility has started with some of the oil leaks cleared and areas around destroyed storage tanks cleared.
The following images captured on the 12th and 30th of March and the 11th of April further confirm that the situation on the ground hasn’t worsened. This illustrates the advantage these remotely acquired images have, as costs and risks that are associated with visiting the site in person, can be reduced.
The timeliness of the service allowed the client to monitor the oil storage facility and the ongoing attacks, as well as clean-up activities when control was regained. This example shows how Airbus’ OneSeries option of the One Tasking service allows frequent monitoring of critical areas on the ground, ensuring up-to-date information is provided to emergency response teams and decision-makers. It demonstrates the crucial position earth observation satellites have in providing up-to-date intelligence, especially when the situation on the ground is dangerous.
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 Thursday 7th September, an 8.2 magnitude earthquake struck the waters off Mexico’s Southern coast. Affecting the states of Chiapas, Oaxaca and Tabasco, the earthquake killed 96 people in the region.
In order to get the first critical information on affected areas and help local authorities quickly react, Airbus’ high-resolution Pléiades satellites were immediately tasked over the impacted region. With multiple tasking plans per day, Pléiades constellation offers an unrivaled optimization of data collection: unforeseen weather changes, as well as last-minute requests, can be taken into account for the first-class level of service.
Detailed and very fresh satellite images were collected and delivered only a few hours after the event struck the Gulf of Tehuantepec. This was thanks to the OneNow tasking option that is ideally suited to plan emergency response on the ground.
The new images were also contrasted with historic images of the areas, allowing experts to understand where private houses, public buildings or infrastructure had been damaged. The images of the city Tonala and Juchitan clearly show the destroyed official Palacio Municipal building, as well as damaged church wall.
It was the strongest earthquake in over a century.
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.
The 2015 Hindu Kush earthquake struck South Asia on the 26th October with a 7.5 magnitude, 260km North-East of Kabul, Afghanistan. The deadly earthquake caused hundreds of deaths and heavy damage in one of the world’s most impoverished and war-torn regions. The Pakistan National Space Agency (SUPARCO), was requested to provide damage assessment maps of the area to inform emergency decisions and rescue operations. The freshest imagery, delivered in high resolution and in the shortest timeframe was needed to produce the maps.To view map click here
The deadly earthquake caused hundreds of deaths and heavy damage in one of the world’s most impoverished and war-torn regions.
The Pléiades images were delivered just two and a half hours after acquisition, due to a fully automated process.
THE SOLUTION & RESULTS
Shortly after the earthquake, SUPARCO’s team placed 5 One Tasking, OneNow emergency requests through the GeoStore online portal at 8:45pm. The Pléiades images were delivered just two and a half hours after acquisition, due to a fully automated process. The near real-time performance allowed SUPARCO’s teams to immediately start their analysis, before rapidly providing 4 detailed damage assessment maps, based on the 50cm Pléiades product. These value-added maps were distributed to all concerned disaster management agencies, providing operational teams on the ground with the intelligence to effectively manage their relief and rescue activities, and to manage the early recovery phase.
- The 24/7 GeoStore web service enabled the immediate request of Pléiades images, and the rapid delivery of damage assessment maps
- Providing detailed damage maps, field team ground operations were efficiently managed
- Operational effectiveness was achieved due to a collaborative relationship with SUPARCO
SUPARCO teams are very grateful to deal with Airbus Defence and Space not only as a data provider but above all as a dedicated partner. Imran Iqbal, Member (SAR), SUPARCO
