Gps data

Definition

GPS data refers to the information collected from the Global Positioning System, a satellite-based navigation system that provides precise location and time information anywhere on Earth. This data plays a crucial role in seismology by allowing researchers to track ground movement, monitor tectonic plate boundaries, and study fault lines with great accuracy.
