Geophysical Data Centre

The mission of theRESIF data centre is to distribute and archive all data from the French permanent and mobile seismological networks.

ISTerre’sGEODATA was in charge of prototyping RESIF’s national data centre (from 2011 to 2016). The data centre, which went into operation at the end of 2016, is currently being co-operated by the University of Grenoble Alpes, the OSUG data centre and the ISterre laboratory.

The GEODATA service is also in charge of data collection and validation platforms for the INSU mobile fleet :SISMOB and for the French accelerometer network : RAP.

RESIF data are freely accessible : http://seismology.resif.fr

RESIF data center contacts

– generic addresses for the data center : resif-dc univ-grenoble-alpes.fr, dc resif.fr

– Helle Pedersen : scientific manager of the RESIF data centre
– Emeline Maufroy : scientific carrier of the platform for data collection and validation of the RESIF accelerometric antenna (RAP)
– Florent Brenguier  : scientific carrier of the RESIF mobile antenna data collection and validation platform (SISMOB)
– Gregory Arneodo : CNRS research engineer
– Catherine Péquegnat : CNRS research engineer
– Jonathan Schaeffer : CNRS research engineer
– David Wolyniec : design engineer CNRS
– Jérôme Touvier : CNRS research engineer
– Rima Bouazzouz : design engineer CNRS

The business expertise of technical staff of the data center are :
– project management, information system architecture ;
– relational databases ;
– seismological databases, data/metadata matching, domain standards (processing, distribution tools, data and metadata formats), access to online databases and the use of international archives ;
– the deployment/development of applications related to the management and distribution of geophysical data.

Specific skills

– Python2.7, C, SQL, scripting tools and language
– Librairies Opspy, libmseed
– seismological data manipulation tools
– access to data via global servers
– seismological data and metadata format

The data collection, processing and distribution activities carried out by the service are upstream of the data mining and intensive exploitation activities. We implement massive and fast data access interfaces related to these activities.

Data center engineers work closely with instrument engineers from the laboratory’s national observation services and facilities.
