Fetch sample GPS velocity data from California (the U.S. West coast).
All sample datasets in Verde are deprecated and will be removed in Verde v2.0.0. The tutorials/examples will transition to using Ensaio instead.
Velocities and their standard deviations are in meters/year. Height is geometric height above WGS84 in meters. Velocities are referenced to the North American tectonic plate (NAM08). The average velocities were released on 2017-12-27.
This material is based on EarthScope Plate Boundary Observatory data services provided by UNAVCO through the GAGE Facility with support from the National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA) under NSF Cooperative Agreement No. EAR-1261833.

pandas.DataFrame) – The GPS velocity data. Columns are longitude, latitude, height (geometric, in meters), East velocity (meter/year), North velocity (meter/year), upward velocity (meter/year), standard deviation of East velocity (meter/year), standard deviation of North velocity (meter/year), standard deviation of upward velocity (meter/year).
Utility function to help setup a Cartopy map.
