Gravity Dataset for the United States Lower 48 states

The terrain corrected United States gravity database is available through the link below. The terrain corrections were calculated by Mike Webring of the U. S. Geological Survey using a digital elevation model and a technique based on the approach of Donald Plouff. The reduction of these data has been updated with modern geodetic datums and a higher precision digital elevation model. In the present version, latitude and longitude values are referenced to NAD83 (North American Datum 83; horizontal datum) and elevation values in meter are referenced to NGVD88 (Vertical datum).
