Post processing tools made available to screen EO data also allow to make nice images using Sentinel-2

The on-demand Band Combination 8 processing service COMBI provides RGB composites from user defined bands of single or multiple data products from a broad range of EO missions. All bands are in their native format e.g. no radiometric correction is applied thus can serve only for fast screening of the data, not for further processing. We are sharing nice results using time series of Sentinel-2 images of the Copernicus programme.

With the majority of TEPS now in the pre-operations phase we look forward for other opportunities to meet all interested users.

Geohazard TEP (GEP) expanding users' base

The GEP (Geohazard Thematic Exploitation Platform) Early Adopters programme is now welcoming new institutions with their users to take advantage of the platform capabilities.

Started in 2015 with 29 users, the GEP Early Adopters programme now includes 61 users and 54 different organisations from 19 countries, read more about this on the the GEP blog.

Users interested in geohazard analysis, GEP tools and the related products are invited to visit the Geohazard Portal.

Landslide Monitoring with Geohazards TEP

Geohazards Exploitation Platform has been used to produce a velocity map of the unstable area around the Aletsch Glacier, the largest in the Alps, which is experiencing an average retreat of about 50 m a year. The adjacent rocks that were previously constrained by the ice mass are progressively being released, generating slope instabilities. For this reason, the Aletsch region is a unique place where scientists can investigate how changes in glaciers affect the long- and short-term evolution of rock slope stability.

Keep an automatic eye on seismic zones

The Copernicus Sentinel-1 twin radar satellites combined with cloud computing are monitoring Europe’s earthquake zones by searching for ground shifts as small as a millimetre. 

Radar was developed in the last century to pick up aircraft moving at hundreds of kilometres per hour. Today’s satellite radar can reveal otherwise invisible shifts in the ground taking place as slowly as the growth of your fingernails.

The new, automatic radar service covers Europe’s seismic regions, monitoring an area of three million square kilometres in 200 m blocks.

Once any motion of interest has been identified, more detailed checks can be made through ESA’s Geohazards Exploitation Platform.

“The quick-browse service has been under way across European tectonic regions since January, harnessing automated processing developed by the DLR German Aerospace Center,” explains Fabrizio Pacini of Terradue, overseeing the Platform.

The GEP is one of six ‘Thematic Exploitation Platforms’ (TEPs)' being developed by ESA in the frame of the Earth Observation ground segment evolution strategy. The TEPs aim at fostering the exploitation of EO data by providing an online environment for users to access information, ICT resources, and tools.

The TEPs are contributing to the creation of an European EO data ecosystem for research and business, one of the overarching objectives of ESA Earth Observation Envelope Programme.

 

Earth's most active volcanoes on satellite watch

 As hundreds flee lava and ash spewed from Mexico’s Colima volcano, its continuing eruption is being tracked not only by ground instruments but also from space. Starting last month, Colima is one of 22 active volcanoes worldwide being monitored by satellites.

The latest observations by Europe’s Sentinels and the US Terra and Landsat satellites are being processed automatically for the rapid delivery of key parameters to geohazards researchers.

“Within the geohazards arena, this kind of systematic service is really something new,” explains Fabrizio Pacini of Terradue, which operates the new service through ESA’s online, cloud-based Geohazards Exploitation Platform, or GEP.

“Researchers already use Earth observation data, of course, but usually on an on-demand basis from a single sensor. We make use of a range of sensors to cover multiple sites on a continuing basis.”

The service is based on automated processing chains developed by GEP research partners, running on the GEP itself, then made available through it.

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:
