National CORS Map

The National CORS Map provides a map interface which allows the user to find and display CORS stations and access data associated with the points. NGS (National Geodetic Survey) coordinates a network of continuously operating reference stations (CORS) that provide Global Positioning System (GPS) carrier phase and code range measurements in support of 3-dimensional positioning activities throughout the United States and its territories. CORS Data - Enable centimeter-level positioning for points of interest - Enable decimeter-level positioning for moving points - Monitor crustal motion - Monitor moisture content for the lower atmosphere - Monitor electronic charge in the upper atmosphere
