Discovery and Delivery of Space Geodetic Data Products from Distributed Archives

This project enhances metadata exchange and user access to geodetic data products through GSAC-WS implementation, QC parameters, and federated search. Updates to SOPAC and UNR processes have further improved data quality. The project also includes an alpha implementation of GSAC-WS capability for legacy repositories. Monthly metrics reporting provides ongoing insights.

  1. Discovery and Delivery of Space Geodetic Data Products from Distributed Archives PI: Frances Boler, UNAVCO Insert an eye-catching yet meaningful picture here. If possible, show the scale of an instrument. • Modernize mechanisms for exchange of metadata for space geodetic products among established archives • Improve user discovery and access to a comprehensive catalog of available products through implementation of the modernized GSAC-WS (Geodetic Seamless Archive Centers - Web Services) • Incorporate new science-based quality control (QC) parameters to enable users to better identify data products applicable for their domain Federated search results shown in new Google Earth display • SOPAC implemented real-time extensions to their site log XML schema and these are provided as output from the GSAC-WS system. • UNR has finalized the process for production of their QA product and completed a re-analysis of 15 million daily files. • An alpha implementation of GSAC-WS capability based on RAMADDA for repositories utilizing legacy GSAC flat file exchange mechanism completed. • Monthly metrics reporting has been initiated.
