About SCEC About CEM

The SCEC Community Geodetic Model (CGM) provides displacement time series and velocities of the Earth’s surface over southern California using data from Global Navigation Satellite Systems (GNSS), which includes the Global Positioning System (GPS), and interferometric synthetic aperture radar (InSAR), both space-based geodetic observation techniques. For detailed instructions, refer to the user guide.
