New interactive tool for seismic data discovery and enhanced data metric access across 13 data centers

The European Integrated Data Archive (EIDA) is a federation of 13 data centres dedicated to securely archiving seismic waveform data and providing seamless access to over 25,000 stations. For the past decade, EIDA’s holdings have been accessed through the WebDC3 interface (https://orfeus-eu.org/webdc3/), which is expected to be replaced with a modernized web interface to address evolving user needs and technological advancements.

The new EIDA web interface introduces significant improvements, including the ability to access data from all 13 federated archives, extending beyond single-centre access to provide comprehensive coverage of the EIDA holdings. Built with JavaScript and the Vue 3.js framework, the interface features a maintainable architecture and modular components for data searching, filtering by parameters such as availability and region, and visualizing additional data metrics through detailed graphs. The actual subset of data selected based on the interactive discovery and selection can be downloaded and includes the three different types of data EIDA currenlty provides via the various federated web services: fdsnws-station (station metadata), fdsnws-dataselect (waveforms), fdsnws-availability and WFCatalog (quality metrics). These features, combined with dynamic table-based filtering, sorting, and advanced visualization, streamline data discovery, selection, and retrieval. The presentation will provide a summary of the current status and offer the opportunity to user to interact with a demo version and provide feedback about new features being developed.

Future development plans for the new web tool include support for Authentication and Authorization Infrastructure (AAI) to enable secure user authentication and access control, enhancing logging and user-specific accessibility. Transparent display of DOI, license, and attribution will improve data traceability and ensure proper citation.
