Description: The use of digital object identifiers (DOI) for scientific data and scientific software is increasingly common practice for more than a decade. As a result of the Coalition on Publishing Data in the Earth and Space Sciences (COPDESS) and other initiatives, DOI-referenced datasets are fully citable in scholarly literature and more and more journals require the availability of data underlying scientific results and their citation. Technical implementations, like Scholix (a framework for Scholarly Link Exchange) enable direct links and between literature and data and support the visibility of research data. Key elements for enabling these links are persistent identifier (PID). These PIDs allow, e.g., to uniquely identify data, scholarly literature and code (via DOIs), persons (via ORCID), institutions and funding agencies (via ROR – the registry of research organizations), via machine-actionable links and should be included in the DOI metadata. Similar to other scientific disciplines, the use of DOI for geodetic data is increasing in the last years. While this is easy for static data, like for global of regional gravitational models or GNSS campaign data, most geodetic data are large (mainly due to the large number of files and high temporal resolution) and highly dynamic (real time data acquisition) and highly granular. Geodetic services of the International Association for Geodesy (IAG) are international key player for geodetic data provision and distribution and their operating institutions and funding agencies increasingly require the provision of tangible data use and access statistics. Credit through citation was a major reason for the Global Geodetic Observing System (GGOS) to establish a Working Group on using DOI for geodetic data sets (GGOS DOI WG) and for the working group members. The GGOS DOI WG was established in 2019 and includes international representatives of IAG Services and geodetic data centres and associated members that aims at developing best practices and recommendations for the consistent implementation of DOIs across all IAG Services and in the greater geodetic community. This presentation will give an update on recent group activities and on the status of DOI minting for geodetic datasets across IAG Services.

Description: The Global Geodetic Observing System (GGOS) is a collaborative contribution of the global Geodesy community to the observation and monitoring of the Earth System. Geodesy is the science of determining the shape of the Earth, its gravity field, and its rotation as functions of time. Essential to reaching this goal are stable and consistent geodetic reference frames, which provide the fundamental layer for the determination of time-dependent coordinates of points or objects, and for describing the motion of the Earth in space. The geodetic observation and analysis infrastructures as well as the high-quality geodetic products provide the foundation for Earth and planetary system sciences and applications. GGOS endeavors to facilitate and enable production and sharing of the Earth observations needed to monitor, map, and understand changes in the Earth’s shape, rotation, and mass distribution. GGOS also advocates the global geodetic frame of reference as the fundamental backbone for measuring and consistently interpreting global change processes as well as the essential geospatial infrastructure to ensure a homogeneous and sustainable development worldwide. GGOS closely works with its parent organization, the International Association of Geodesy (IAG), especially its components, the Services, t Commissions, Inter-Commission Committees and dedicated Projects to keep these fundamental geodetic contributions sustainable. Additionally, GGOS supports the IAG by strengthening external and interdisciplinary relations and contributions to the broader community, including the Group on Earth Observations GEO and relevant United Nations groups, in particular UN-GGIM Subcommittee on Geodesy and the new UN Global Geodetic Centre of Excellence.

Description: This presentation covers the 10 year history of GGOS Japan. As many as six Japanese national institutes have been operating large-size geodetic facilities with VLBI and/or SLR in Japan and also in Antarctica, and they had been involved in each geodetic service rather independently. In 2013, we initiated "GGOS Working Group" in Japan to enhance the communications among the Japanese institutes and global geodesists and also to encourage collaboration beyond each technique. GGOS Japan is basically a loose network, but it has a chair, a secretary, an outreach representative, working groups (currently active: Data DOI working group) and representatives of each geodetic technique (VLBI, SLR/LLR, GNSS, DORIS and gravimetry). We regularly host annual meetings and sometimes small meetings with focused issues. We have also involved in organising or supporting scientific sessions in domestic and international conferences. During the 10 years history, it was positioned as a GGOS Affiliate in 2017 and we renamed it as "GGOS Japan" in 2019. Basara Miyahara was elected as the GGOS President in 2019. GGOS Japan's webpages are being updated on the GGOS Website, and we have contributed to GGOS YouTube channels. We often set focused activities. We are currently working on the review of ITRF2020 from an operating point of view, and we are also working on a possible best location for a future GGOS Cores site in Japan. In the future we hope to collaborate with international communities, in particular with other GGOS Affiliates.

Description: The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) is a collaborative contribution of the global geodesy community to the observation and monitoring of the Earth System. Geodetic observation techniques and analysis infrastructures, as well as high-quality geodetic products, provide the basis for advances in Earth and planetary system sciences and for various applications. One main objective of GGOS is to support activities and initiatives to communicate the value of Geodesy to science and society, as well as contribute to understand and solve complex issues facing the global geodetic community. Towards this objective, GGOS has established and maintains a website ggos.org, which serves as a point of entry to Geodesy to facilitate discoverability and usability of geodetic data and products. This includes user-friendly and illustrative descriptions about geodetic observation techniques and results. GGOS has also recently produced short videos to explain the value of Geodesy to non-geodesists. The new “Discover GGOS and Geodesy” video is available in multiple languages (youtube.com/@iag-ggos). Presently, GGOS is working on the implementation of a comprehensive geodetic portal, the GGOS Portal (ggos.org/portal), which should realize in future a comprehensive and descriptive source of geodetic information with detailed metadata. With this, GGOS engages with diverse user communities to increase awareness of Geodesy and the ever-expanding utility of Geodesy in everyday applications.
