UNAVCO Geodetic and Related Data Resources

UNAVCO promotes research and learning by providing access to several types of data that our community of scientists uses for quantifying the motions of rock, ice and water at or near the Earth?s surface. Geodetic GPS/GNSS Data (Global Navigation Satellite System / Global Positioning System Data), enable millimeter-scale surface motion measurements at discrete points. Geodetic Imaging Data are collected by a variety of different sensors deployed on satellites, aircraft, and on the ground, and provide high resolution terrain models and deformation measurements over areas of tens of meters to hundreds of square kilometers. Data collected from Strain and Seismic Borehole instruments measure the deformation at or near the surface of the Earth and measure rock physical properties in the vicinity of the installations. At many of the sites where geodetic measurements are made, Meteorological Data are also collected to aid in the processing of the geodetic data.
