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:

http://meetingorganizer.copernicus.org/EGU2016/session/22336).

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:

GEP Community Survey online questionnaire

It will be open from the 1st to 21st of March, 2016.

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.

Welcome to the Urban TEP

The main goal of the Urban Thematic Exploitation Platform (TEP) is the implementation of an instrument that helps addressing key research questions and societal challenges arising from the phenomenon of global urbanization.

Therefore, the Urban TEP represents a web-based platform that allows users to effectively utilize Earth Observation (EO) imagery and existing auxiliary data (e.g., geo-data, statistics) to measure and assess key properties of the urban environment and monitor the past and future spatiotemporal development of settlements.

Key elements of the Urban TEP are the provision of easy and high performance access to EO data streams and archived data, multi-mission and multi-source data management and processing infrastructures, modular pre-processing and analysis procedures (value-adding processors), user-oriented functionalities for product and service development, validation and standardization as well as exchange and distribution of ideas, methods and thematic layers.

To maximize the relevance and societal benefit of the Urban TEP, the initiative includes a comprehensive concept for active expert knowledge and user community integration. Hence, the Urban TEP core consortium – consisting of 5 partners - is supported by a network 6 key user communities including the group of scientists conducting the Group on Earth Observation (GEO - Task SB-04 Global Urban Observation and Information), the World Bank Group, the European Environment Agency (EEA), DG Regio of the European Commission, the International Society of City and Regional Planners (ISOCARP) and the City of Prague. In addition, 7 associated consultancy partners will bring in their expertise and competences in key sectors relevant for the Urban TEP development, implementation and sustainability.

Accessing Sentinel-1 Orbit files on Geohazards TEP

Several ESA Geohazards Exploitation Platform (GEP) early adopters applying for the scenario 2 ‘New EO Service Development’ are currently supported for the integration of their data processing chain on the GEP Cloud environment. 

The resulting processor integration is then made available from the GEP Portal to users (upon sign-in credentials for https://geohazards-tep.eo.esa.int/). On the Portal, authenticated users can select data over an area of interest, set processing parameters, run a processing job and share their results on the platform.

To support these processor integration activities, we have defined an application template, dedicated to the access and the processing of Sentinel-1 data from the Platform. The template, together with the installation procedure, is available on GitHub

Based on this application template, under src/main/app-resources/myapp/run, developers of new Processing applications can now retrieve from the Platform’s catalogue the Sentinel-1 products together with the Precise Orbit Ephemerides data (or POD).

From a running workflow, a function is typically getting the start/end time of the current Sentinel-1 product to be processed, and an OpenSearch query is then performing the retrieval (using the “enclosure” parameter, that provides with the file download location) of the corresponding PODs. A last step is downloading the orbital data from the enclosure reference, and storing it on the proper file system location, in order to be ingested by the SAR processing code embedded in the new application.

In average, ESA releases the Sentinel-1 POD Precise Orbit Ephemerides 20 days after the related acquisition. If you want to process Sentinel-1 products acquired in near-real time, you can also use the orbital data enclosed within the Sentinel-1 product.
