To achieve the goal, EPOS GNSS:
► facilitates access to relevant and validated GNSS data, metadata, and data products
► coordinates the archiving of relevant GNSS data, metadata and data products
► promotes best practice for GNSS station operation, data quality control and data management
► maintains and distributes open source software for GNSS data, metadata and product discoverability
► maintains and develops GNSS data products
The EPOS Thematic Core Service GNSS Data and Products has developed an open source platform, called GLASS, to store and disseminate data and metadata from GNSS stations operating in Europe. In collaboration with EUREF, various GLASS nodes are linked together to provide a single point of access through web portals to: validated GNSS station metadata, the GNSS data itself and derived GNSS products such as position time series, velocities and strain rate maps.
a new way of accessing GNSS data and products for Solid Earth Science researchers
GNSS Products Portal – The portal enables access to the GNSS observations and products. Graphical interfaces enable station visualization and multiple queries over stations and associated metadata allowing users to retrieve the desired information. At the GNSS Product portal is possible to download derived GNSS products such as position time series, velocities and strain rate maps.
Data Gateway Portal –This is an e-infrastructure to store and disseminate GNSS data and products from existing Research Infrastructures. The portal stores EPOS stations metadata and enables access to the GNSS observations and products. The GNSS Data Gateway is where people can search for available GNSS data from all over Europe, including EUREF Permanent GNSS Network (EPN) data.
M3G Portal – The portal where operational centres (which operate the GNSS stations) can upload information about the type of instrument and antenna they are using, when it was installed, which type of receiver, contact information, name of station and network etc. M3G is the central access point for operational centers to upload the log-files of their GNSS stations.
Virtual Machine – To distribute the software to the various partners, the UBI team has put together a virtual machine, or simply VM, with most of the software that all partners have been developing pre-compiled and installed.
