The GGOS Bureau of Products and Standards: Description and Promotion of Geodetic Products

Abstract

The Bureau of Products and Standards (BPS) is a key component of the Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG). It supports GGOS in its goal to provide consistent geodetic products needed to monitor, map, and understand changes in the Earth’s shape, rotation, and gravity field. In addition to the operational structure, the Committees “Earth System Modeling” and “Essential Geodetic Variables” as well as the Working Group “Towards a consistent set of parameters for the definition of a new Geodetic Reference System (GRS)” are associated to the BPS. This contribution presents the structure and role of the BPS. It highlights some of the recent activities, which are focused on the classification of geodetic products and on the generation of user-friendly product descriptions to support the establishment of a comprehensive Internet portal for Geodesy under the responsibility of GGOS. The GGOS website www.ggos.org serves as an “entrance door” and information platform to geodetic data and products, and should become an essential tool to make these data and products easier findable and accessible. With this, GGOS is contributing to address different user needs (e.g., geodesists, geophysicists, other geoscientists and further customers) and to make other disciplines and society aware of Geodesy and the importance of its products.
