What is geodetic surveying?
How do geodesists use GPS?
Geodesy is the science of accurately measuring and understanding the Earth's geometric shape, orientation in space, and gravity field. Using GPS, geodesists can monitor the movement of a site (orientation in space and gravity field) 24/7.

The movements of Earth's surface in the U.S. are monitored by NOAA's National Geodetic Survey through its nationwide network of permanent GPS stations called Continuously Operating Reference Stations.
23 hours ago · The National Geodetic Survey can't change what's really happening, but we can at least measure and monitor it and provide that information so others can use it to the best of their abilities to make sure that they have the best information about the actual heights of places and survey marks used for development and analysis and monitoring of change over time, regardless of what the cause is ...
These videos from NOAA's National Geodetic Survey offer a deep dive into the science of knowing where you – and everything else is in the world! The National Science Teaching Association (NSTA) includes this resource in its database.
Learn about NGS survey projects or submit your own to share with NGS and others. New Datums: The North American Datum of 1983 (NAD 83) and the North American Vertical Datum (NAVD 88) will be replaced in 2022 to improve alignment with reference frames and improve accuracy of GPS-derived heights.
