Crustal Dynamics Data Information System (CDDIS)

The Crustal Dynamics Data Information System (CDDIS) is NASA’s public, active archive of space geodesy data, derived products, and related information. The CDDIS is funded by NASA but cooperates extensively with the international community in support of Earth science research. The CDDIS supports a large international community of geodesy, solid Earth, and natural hazards researchers by providing timely access to the contents of its archive. The archive includes Global Navigation Satellite System (GNSS), Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI), and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) data as well as products derived from these data. The CDDIS is one of NASA’s Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs). All data, products, and information are online and openly available through anonymous ftp and web access.
