News and Activities
GGOS IberAtlantic (GGOS IA) functions as a regional node of GGOS, focusing on geodetic activities across the Iberian Peninsula and the Atlantic region. GGOS IA fosters collaboration among geodetic institutions while promoting scientific research and technological development tailored to the region’s unique geophysical characteristics.
GGOS Portal Survey
GGOS, 🏛️ Organisation NewsThe services of the International Association of Geodesy (IAG) provide very important and valuable geodetic data, information, and data products that are increasingly relevant for Earth System research, including monitoring of global change phenomena and a wide range of diverse applications such as satellite navigation, surveying, mapping, engineering, geospatial information systems, and so on.
Currently, it is difficult for many people to obtain an overview of all available geodetic products and data. The Global Geodetic Observing System (GGOS) of the IAG aims to fill this gap by developing the GGOS-Portal, which will serve as a central search and access point for geodetic data and products (one-stop shop). Data and products will be described by detailed metadata and remain physically located at their originating data centers of each contributing IAG service and other data providers. The GGOS-Portal will only synchronize the provided metadata and include it in its platform to ensure better discoverability. In the long term, the GGOS-Portal can provide a set of tools for organized knowledge search, including visualization to support identification and selection of appropriate resources (information, data, products).
In general, geodetic data portals are a dime a dozen. However, the GGOS portal will be much more than just a data portal for geodetic data from the IAG Services. The combination of the easy understandable descriptions of products and observation techniques with this comprehensive source of detailed geodetic metadata makes the future GGOS portal unique.
GGOS is now conducting a survey to inquire the opinions of geodetic data users on data availability and visibility and to identify requirements for a comprehensive and user-friendly GGOS-Portal. In addition GGOS will obtain an overview of the current availability of data products and their metadata. Please take 10 to 15 minutes and participate in this survey to help us developing the GGOS Portal, a future unique access point for geodetic data and products: https://geodesy.science/ggos/portal/

G06 Monitoring and Understanding the Dynamic Earth with Geodetic Observations
Convener(s): Basara Miyahara (Japan)
Co-Convener(s): Detlef Angermann (Germany) Allison Craddock (USA) Hansjörg Kutterer (Germany)
Description
Geodetic observations of the Earth’s shape, rotation, and gravity show that these Earth properties change on a wide range of timescales reflecting the wide range of processes affecting them, from external tidal forces to surficial processes involving the atmosphere, oceans, and hydrosphere to internal processes acting both at the core-mantle boundary as well as within the solid Earth itself. Measurements of the Earth’s shape, rotation, and gravity can therefore be used to gain greater understanding of mass transport within the entire Earth system, from tracking water in its various phases as it cycles through the atmosphere, oceans, and land, to crustal deformation associated with tectonic motions and glacial isostatic adjustment, to torsional, rotational, and inertial oscillations of the core. Geodetic observations provide the basis on which future advances in the geosciences can be built. By considering the Earth system as a whole (including the geosphere, hydrosphere, cryosphere, atmosphere and biosphere), monitoring Earth system components and their interactions by geodetic techniques and studying them from the geodetic point of view, the geodetic community provides the global geosciences community with a powerful tool consisting mainly of high-quality services, standards and references, and theoretical and observational innovations. Earth observations are needed not only for scientific research but also for societal applications such as disaster prevention and mitigation, managing resources like energy, water, and food, mitigating the effects of climate change, and protecting the biosphere, the environment, and human health. Geodetic observations provide the metrological foundation for Earth observations and provide the means to determine mass transport in the Earth system. Geodetic observations are therefore a cornerstone of the Earth observing systems needed for scientific research and societal applications. This Symposium will highlight the importance of geodetic observations to monitoring and understanding the dynamic Earth system for the benefit of both science and so
