In addition, we will be exhibiting and doing demonstrations at the Applications and Platforms stand on Floor 2, so if you have a specific point of interest then please come along and ask.

Geohazards TEP@EGU 2016 wrap-up

 The EGU General Assembly 2016 was held in Vienna from 17 to 22 April with great success, with 4,863 oral presentations given, 10,320 posters, 947 PICO sessions and a total of 13,650 scientists from 109 countries taking part.

The Geohazards Exploitation Platform (GEP) featured in the interesting discussions of the Geoscience community, being subject of five presentations and a training session during the first three days.

 

 

On Monday, the new functions built into the GEP to support results publication ad sharing were presented to the GEO Supersites community.  All appreciated the clear contribution the GEP will make to enable Open Science for the Geoscience community, a key element of the GEO Supersite initiative.

New processing results of the GEP were also presented, including:

  • A preview of the new InSAR Browse Services developed by German Aerospace Center (DLR) in the context of their GEP pilot (more information on this service will follow on the GEP blog).
  • A continental scale map showing 12-days Interferometric Coherence of almost all of Europe, processed by scientists of CNR-IREA.
  • Sharing of results with an example from the 2015 earthquake in Chile (see yourself on GEP)

On Tuesday, examples of the SBAS processing chain and time series analysis were shown, with availability of per-pixel time series over Campi Flegrei, the Gargano area and Mount Etna.  The second presentation focused on the integration of the SBAS algorithm into processing services through the GEP, and described how the GEP makes it possible to realize a wide spectrum of service modes, like an on-demand mode and a surveillance mode systematically updated at each new acquisition.

On Wednesday, the GEP “Optical Image Correlation” pilot project was presented.  The project is led by University of Strasbourg and the team is implementing a processing chain on the GEP cloud-based (Hadoop, MapReduce) environment, which will enable analysis of surface displacements at local to regional scale (10-1000 km2), targeting in particular co-seismic displacement and slow-moving landslides. 

A training course for the GEP SBAS-DInSAR web tool was held. The course provided a short overview on the DInSAR processing methods allowing retrieving mean surface deformation maps and displacement time series, with a specific focus on the SBAS-DInSAR technique. Secondly, the GEP and G-POD environments were introduced and the P-SBAS web tool presented. Finally, the advanced features as well as some main results achieved via the web tool were shown.

In all of these presentations, we saw geoscience research and IT coming together in the GEP as geoscientists manage to introduce new concepts coming from the evolving IT world into their algorithms, leading to reduced execution times and new processing scales that allow for previously unfeasible analyses.  This development is being warmly received.  For instance, when the current scenario of growing satellite data was discussed at the “Integrated Research Infrastructures and Services in Geosciences” session in presence of  representatives from the European Plate Observing System (EPOS), the TEP model was presented as an answer to manage the concerned challenges.  The general consensus among the EGU audience was that we are living interesting times, in which the needs of the research infrastructures are shaping the evolution of the ICT and  governance is being negotiated by user communities in view of solutions that are sustainable in the long term.

New S1 InSAR processing service

On-Demand Sentinel-1 InSAR processing service

The Sentinel-1 mission flying under Europe’s Copernicus Programme offers a powerful system for monitoring surface displacement through the Interferometric SAR (InSAR) technique.  It acquires Synthetic Aperture Radar (SAR) data on a global scale, and operates under an open and free data access policy.

The satellite uses an Interferometric Wide Swath (IWS) mode to obtain the raw digital radar data about the Earth’s surface.  Accurate and specific processing algorithms are required in order to turn this raw data into visual information products, and this layer of expertise can discourage users who are not familiar with InSAR techniques from using the data.

To promote wider use of Sentinel-1’s SAR data, increase research on interferometric techniques and make it easier for people to produce accurate Sentinel-1 InSAR measurements, CNR-IREA has developed a web tool which, through a user-friendly interface, enables users to generate interferograms in an automated and unsupervised way (see Figure 1). With this service, users can select SAR images from the Sentinel data repository, set a few processing parameters, and then automatically process imagery and retrieve the interferogram which shows the changes in the surface area detected by the radar.

CNR-IREA developed its InSAR web tool in the context of the Geohazards Thematic Exploitation Platform (Geohazards TEP). Designed for exploitation on the Geohazards TEP, the web tool has been available to users from the geohazards community since April, as an initial prototype in ESA’s Grid Processing On Demand (G-POD) infrastructure. The prototype will evolve into a pre-operational service on the Geohazards TEP by early 2017.

A short course on how to use CNR-IREA’s InSAR web tool on the Geohazards TEP will be given at the next EGU General Assembly (see here for details:

ESA TEPs @ BiDS 2016 conference

It was an exciting three days packed with presentations and demos, but most importantly, also a place for exchanging ideas, brainstorming and networking. BiDS this year was a very successful conference and left me with the feeling that "everybody" was there. For sure, the attendance was much more than had been expected, around 300 people or more I would say, probably also thanks to the amazing location of the "Auditorio de Tenerife", in the beautiful Canary Islands.

This year, the conference had a lot of "Exploitation Platforms" talks. Beside two dedicated sections, one of which in a plenary, all the other ones had some kind of "platform" inside. For me, it was the affirmation that Big Data nowadays goes in parallel with the concept of platforms and that Earth Observation is following, and in some cases driving, this trend. For sure, after this conference, everybody could see as a fact that the future of Earth Observation follows tightly the concept of "bringing processing to the data" and I think this is a big success for ESA and the TEPs, which have been pioneering this approach for a couple years.

On the second day, I had the honour of providing a presentation about the common Open Architecture, standardization and OSS framework activities that ESA is doing together with the the TEPs and other sister initiatives. The feedback from this activity was very positive, even more than I expected, with many people interested to join in, from the Copernicus services to other industry-lead independent EO platform activities. I certainly came back with the feeling that our work on the open architecture is useful even outside ESA, in the more wide EO data and Big Data ecosystem.

So, I would say BiDS was a success, not only from the point of view of ESA and the TEPs, but also on the personal side. I had the chance to meet and discuss with lots of people and start collaborations which I think will be very mutually beneficial in the future. I'm looking forward to finding everyone back again, with new ideas and updates, at the next BiDS'17 conference in Toulouse, and probably for most people, also at the Living Planet 2016 symposium in Prague.

Happy EO Platforms to everyone!

TEPs at Big Data from Space

If you are attending Big Data from Space make a note of the following speakers:
 
S. Clerc (Coastal TEP) : Big Data and Tools, the Thematic Exploitation Platform Concept (Day 1)
This paper attempts to provide some best practices for the design of Earth Observation (EO) data exploitation services, collected from the observation of successful realization and trends. On-line exploitation, in particular through dedicated thematic platforms, is considered a key concept to allow common users to harness the power of Big Data in Earth Observation.

S. Pinto (ESA lead architect) : Exploitation Platforms Open Architecture (Day 2)
This presentation will summarise the status of the TEP architecture, discussing the lesson learnt from the single TEP projects and the current Exploitation Platform Open Architecture draft. It will also present the status of the standardization work of the Exploitation Platform interfaces, performed in close connection with the HMA working group and the plans for the evolution of the Exploitation Platforms harmonization activity.

R. Tergueff (Forestry TEP) : Services and User Support on the Forestry Thematic Exploitation Platform (Day 2)
The F-TEP services cater for users with varying familiarity with EO data and processing. Each user group is supported by providing an interface that they feel comfortable working with, and which helps them to achieve their goals for forestry data products with ease. As users grow with expertise and confidence and want to pursue more complex tasks, they can proceed to unlock new functionalities. With this model, F-TEP can act as a learning platform as well.

 

Geohazards Community Online Questionnaire

This link brings you directly to the Community Survey online questionnaire

Today we are opening an online survey to involve more parties from research, industry, administration and government authorities in the evolution of the Geohazards Thematic Exploitation Platform (GEP) services.

GEP is an R&D activity developing a new ground segment operations approach, complementary to the traditional operations concept, and demonstrating the benefit of new technologies for large scale processing of EO data. 

The platform is intended to support initially the global geohazards community’s objectives, as defined in the context of the International Forum on Satellite EO and Geohazards, organised by ESA and GEO in Santorini in 2012. In particular, GEP is a follow-on to the SuperSites Exploitation Platform (SSEP), an ESA initiative to support the Geohazards Supersites & Natural Laboratories initiative (GSNL) of the Group on Earth Observations (GEO).

GEP allows both on-demand processing for specific user needs and systematic processing to address common information needs of the geohazards community as a whole, as well as massive processing on multi-tenant computing resources on the Cloud. Such capacities will address the challenges of monitoring tectonic areas on a global basis, and of studying a range of geohazards. To exploit the geo-information generated using the Platform, GEP leverages open APIs for the integration of interactive processing and post-processing services.

The Platform follows a model for partnership and community building that is user driven. Fundamentally the current solution has been designed from working on user requirements from the GEO initiative on Geohazards Supersites and the CEOS Working Group on Disasters, with its Seismic Pilot involving a range of expert users such as for example the University of Leeds for UK’s COMET, ISTerre for the french Formater network, the italian Istituto Nazionale Geofisica & Vulcanologia, UNVACO, or NASA/JPL and University of Miami in the USA.

The evolution of the current platform into an operational service is following a capacity building process driving the requirements, design and implementation activities. This process includes a mechanism to gather user needs in liaison with the following types of organisation: 

  • Geo-science community incl. Universities (PIs) worldwide;
  • Organisations with a national mandate concerning risk assessment (incl. seismological centres);
  • Specialists of geohazard risks in other sectors (pre-commercial research affecting insurance/reinsurance sector, civil engineering companies, energy, etc.);
  • National & regional civil protection agencies and national & local authorities with a risk management mandate (potentially for both prevention/preparedness and response).

This process allows the GEP consortium to design functionalities able to meet prioritized user needs in view of efficient and cost effective operations. 

The programme of work covering the period 2016­-2017 will pursue activities with the Platform’s early adopters and will evolve the 16 processing applications currently available to exploit conventional and advanced InSAR processing for precise motion monitoring. The activity will develop six Pilot projects to demonstrate the potential of federated processing of EO data on the Cloud: a new pilot on photogrammetric processing using optical EO data with Univ. Strasbourg (France), the integration of optical based processing method for volcanic hazard monitoring with INGV (Italy), a pilot on terrain motion surveillance with CNR-­IREA (Italy), the systematic processing of Sentinel­-1 interferometric quick looks with DLR (Germany), the integration of a PSinSAR chain for precise terrain motion mapping with Altamira Information (Spain) and an exercise with the Corinth Rift Laboratory to test and exploit the platform processors and services to support geohazards science in this seismic part of Greece. In this course, the GEP will expand its overall user base to gradually reach a total of 60+ registered user applications in 2017.

This growing user community is a key aspect for the GEP consortium so we have created an online questionnaire to involve more parties from research, industry, administration and government authorities in the evolution of the platform’s services.

You have now the opportunity to contribute your needs and expectations in terms of functionality enhancements, use scenarios, services portfolio, data provisioning and concrete benefits for the GEP users.

The online survey is structured in 5 parts, and on average, it will take only 10 minutes to complete:

  1. About you
  2. Your thematic interests and current practices
  3. You as a geohazards platform user
  4. Your objectives with EO data [ incl. a branch for SAR experts ]
  5. Finally, your vision of a research community platform

You can access the survey by following this link:

Report of the User Consultation on Disaster Risk Reduction (DRR) & new satellite EO methods

On 27th November 2015 ESA hosted a User Consultation on Disaster Risk Reduction using new satellite EO methods jointly organised by e-GEOS and ALTAMIRA INFORMATION in the framework of the General Studies Programme (GSP) led by the European Space Agency. These studies are looking at new Earth Observation (EO) methods & new ICT technologies to improve the understanding and management of natural hazards.

The primary objectives of the event were to better understand geo-information requirements about Disaster Risk Reduction, share ideas about new methods and new underlying technologies to exploit satellite EO for hazard and risk mapping and identify issues for which innovative techniques could be tried in the themes: landslides, earthquakes, flooding & volcanoes.

A total number of more than 40 participants belonging to more than 20 different public or private organizations from 10 different countries and staff from international organisations such as the United Nations joined the event and actively contributed to the working sessions.

New hazard mapping to demonstrate the contribution of satellite data to DRM in Bhutan and Nepal.

ESA has originated a pilot project in the framework of eoworld2, a collaboration between the European Space Agency and the World Bank, to demonstrate the benefit of satellite EO to support Disaster Risk Reduction (DRR) in Nepal and Bhutan.

The Hindu Kush Himalayan Mountains are the source of 10 major river systems and provide vital ecosystem goods and services to more than 1.4 billion people spanning a range of countries from Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal to Pakistan.

The World Bank has numerous on-going projects in the Himalayan mountain region, ranging from agriculture, rural roads, climate change, watershed management. In Nepal and Bhutan it is actively involved since several years in projects related to hydroelectricity and infrastructure planning (roads, dams, agriculture) and makes use of existing national data provided by the involved agencies from both countries.

The pilot is conducted by a Swiss team comprising of MFB-GeoConsulting GmbH, Gamma Remote Sensing AG and SUPSI-IST. Project users include World Bank staff and local users involved with risk management and sustainable development.
