Abstract:
Geodesy aims to determine the geometric figure and the gravitational field of the Earth, as well as its orientation in space. Steadily increasing accuracies, with which these tasks are being solved, are based on corresponding improvements in geodetic measuring data, both, on the quantitative as well as the qualitative level. Similar developments in the acquisition, processing and analysis of observation data, which have always been at the limit of the technically and scientifically feasible, are witnessed in the fields of seismology and geomagnetism as well. Recently however, innovative developments, building on Big Data approaches, are emerging with the combination of diverse data streams into integrated processing environments. Geodetic, seismological and geomagnetic observation data are fundamental for a better understanding of Earth system processes. The combination of these geoscience data collected by ground- and space-based sensors, their consistent processing, validation and assimilation into complex Earth system models contribute in an essential way to the future implementation of GGOS, the Global Geodetic Observing System.
