|Gravity Data For The Maryland/Virginia Area
|The gravity station data (5,905 records) were compiled by the U. S. Geological Survey.
This data base was received on July 11, 1997. Principal gravity parameters include
observed gravity, Free-air anomalies and Bouguer anomalies. The Bouguer gravity anomaly
values were computed using the 1967 gravity formula (International Association of
Geodesy, 1971). See Open-File Report 90-265 for further information.
