The European Plate Observing System (EPOS) has been established to facilitate, harmonize and standardize data collection and processing for Solid Earth Research applications. The EPOS is principally based on the existence of national and pan-European infra-structures while it is completed with Thematic Core Services (TCS) for individual scientific domains, and Integrated Core Services (ICS). Besides geophysical data and products, the contribution of geodesy to EPOS is currently represented mainly with GNSS data and products. As Europe is covered by various networks of GNSS stations maintained by variety of agencies with different technical and scientific objectives, the GNSS TCS has been established in order to integrate as many as GNSS data and products. For this purpose, the TCS developed a new distributed system disseminating and controlling data and metadata, and which enables an easy data search, selection or download for any specific application.
Within the EPOS Implementation Phase (EPOS-IP) project, a major effort in GNSS TCS targeted these developments: a) new distributed system for GNSS data dissemination and quality control, b) pan-European products such as coordinate time-series, velocity fields and strain-rates and, finally, c) sustainable model for data, data products, software and services provision and maintenance in future operational phase which will start in 2019. The poster focuses on developments towards a new way of data dissemination including new GLASS software, data and metadata quality control. It presents the overall concept, implemented architecture, software and portal components, the technologies that are used and resulting API’s and their descriptions in formal languages for integration into the central EPOS project software and the existing workflow system. The EPOS-IP project is funded by the ESFRI European Union.
