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.
