GPS Velocity Viewer
This interactive tool allows users to see GPS/GNSS-measured crustal motions around the globe in a wide range of reference frames. The default view shows horizontal motions in the North American reference frame but users can choose to add vertical motions, earthquakes epicenters, plate boundaries, volcanic centers, or other reference frames. The tool can also be used as an interface to learn GPS/GNSS station names and download time series data.
Could be used in nearly any circumstance when learners are studying plate tectonics. Gives learners a chance to explore crustal motion of a region of interest to them.
- Strongly encouraged to have users watch the short video How to Use the GPS Velocity Viewer
- It is helpful for users to understand reference frames Tutorial: GPS Velocities Reference Frames or YouTube video: Measuring Plate Tectonics with GPS [see minutes 0:40-1:30 for reference frames])
