Data policy

The Epos-France seismological data center (SDC) mostly delivers open-access data and in some cases, restricted-access data from temporary networks. The distribution of open data is our priority concern, and will benefit – in case of resource shortage – from most of our manpower and computing infrastructure capabilities.

  • Open-acess data is available, at any time, from our request engines (FSDN webservices, EIDA, seedlink). We also operate a rsync service that makes it possible to download/sync datasets;
  • Mobile (temporary) networks data is often restricted-access for an average time period of three years after the experiment is closed. A login and password is usually required to download this data, after the Principal Investigator of the experiment provides the datacentre with his agreement;
  • Networks metadata is always public. Thus, you may browse full inventories and maps without needing any specific access grant.

DOI

Some of the Epos-France data sets have DOIs (Digital Object Identifier) associated with their seismic network according to the standard procedure approved in 2014 by the FDSN.

If you are using Epos-France data for your work (research, engineering, education), you must follow these citation guidelines.

Quality Assurance

  • the delivered data necessarily have associated metadata;
  • the data center does not make any modification on the data that is entrusted to it and delivers them as is
    the delivered data are of different qualities :
    – raw: no quality check is applied;
    – modified/validated: different processes are applied according to the management policy of each network. They can be corrected in time, holes filled, etc. More information
