Scientists generally use two tools to look at GPS data when studying tectonics: time series and velocity vectors. We'll use station CAT3, on Catalina Island off the coast of California, as an example.
A time series is a graph that shows how positions change over time (Figure 1).
A velocity vector is an arrow that shows direction and speed of motion of a GPS site. The velocity vector for each site shown in Figure 2 is calculated from data like those shown in Figure 1.

The site was originally developed by the GPS Reflections Research Group at the University of Colorado (CU) using funding from NSF EAR1144221. It was built by Evan Pugh and Kristine Larson at CU and by the UNAVCO Education and Community Engagement Program.
