Abstract
Interoperability of data and products among disciplines is becoming a key aspect within the scientific community to allow the optimal integrated exploitation of data, taking advantage of modern real-time work-flows using also AI techniques.Within the EWRICA project, aiming at creating robust local ground motion models shortly after an earthquake to assess secondary effects such as tsunamis and landslides, one of the tasks focussed on integration of near-field seismo-geodetic data into real-time source inversion. To enable this task, Real-Time Precise Point Positioning (RT-PPP) data have been converted to miniSEED records on the fly by using a tailored plugin for SeisComP developed within the project. The real-time data in GFZ Displacement Real-Time (GDRT) format have been mapped to miniSEED channels as described in the SeisComP documentation [1]. The initial mapping has been defined considering also one additional use case implemented in the TURNkey project where RT-PPP data were generated from a newly developed standalone instrument. RT-PPP has been integrated in the data flow and sent out to clients via seedlink for processing in the known data and metadata format enabling faster and improved assessment of seismic moment, hypocentre and rupture kinematics.In this presentation we introduce the gdrt_plugin released for the first time in June 2022 with the SeisComP v5.0.0 [2], we outline the initial process of mapping the GNSS products to existing data and metadata formats and would welcome discussions about further integration in seismology through the FDSN.[1] https://www.seiscomp.de/doc/apps/seedlink.html#seedlink-sources-gdrt-label[2] https://github.com/SeisComP/seiscomp/releases/tag/5.0.0
