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 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.
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
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.
Marie Hakova from GISAT comments on One Tasking
“We’ve been using GeoStore for the past 2 years and the ease of both tasking new imagery and accessing archive satellite data from Airbus Defence and Space, has been highly appreciated by my clients. GeoStore is an easy way to order archived data that can be received within two hours or less – making product delivery quick and efficient. Tasking the satellites has never been easier, and now includes the option of getting feasibility studies within GeoStore and offers more programming services with Pléiades One Tasking – containing four options:
- Pléiades OneDay
- Pléiades OneNow
- Pléiades OnePlan
- Pléiades OneSeries
Computer programmers did an excellent job and impressed potential clients within the defence-intelligence market, in particular. This is due to the extraordinary ability to programme data one day and getting the next available image (depending on cloud cover, of course). Clients receive the data within two hours of their acquisition, thus being able to assess critical security threats immediately.”
I am personally very pleased that such service is now available. Over the years, being able to communicate users’ needs back to satellite data providers (and vice versa) confirms the Airbus Defence and Space GeoStore online database is a really great solution.
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 & 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.
The Airbus’ constellation’s daily revisit capability and high-resolution satellites were used to track damage caused over time and organise recovery operations.
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.
The Langkawi International Maritime And Aerospace Exhibition in Malaysia represents Asia’s premier maritime and aerospace event. Airbus was one of the key exhibitors at the exhibition, which ran from the 21st until the 25th of March 2017. To promote Airbus’ attendance, it tasked its OneDay service to capture and deliver high-resolution images of the event location during the course of the exhibition. Situated close to the equator, Malaysia’s cloud coverage can make the acquisition of crisp satellite images a challenge. However, due to OneDay’s unique nature, imagery acquisition has now become risk-free. Customers are able to postpone or confirm a booked acquisition up to 12 hours before the acquisition date due to any change in requirement or if a weather report suggests the results will be compromised by cloud coverage.
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
