GEOID90 was the first high-resolution geoid model for the United States computed at the National Geodetic Survey. It did not contain data for Alaska, Hawaii nor Puerto Rico.

GEOID90 was disseminated on 5 1/4" floppy disks only. It is being made available on the web for historical, investigative purposes only. NGS recommends the use of only our latest geoid model. See the NGS geoid page to find out what that model currently is.
