Description:

GEOID18 is the National Geodetic Survey’s (NGS) latest hybrid geoid model, which enables GPS users to access orthometric heights that are consistent with official vertical datums of the National Spatial Reference System (NSRS). GEOID18 covers the 48 CONtiguous United States (CONUS), Puerto Rico, and the U.S. Virgin Islands, includes 1 arcminute grids for the geoid height, the geoid height estimated uncertainty, and deflections of the vertical (DEFLEC18), and is accessible at geodesy.noaa.gov/GEOID/GEOID18.
