|Gravity Data for Minnesota
|The gravity station data (55,907 records) were gathered by various governmental organizations
(and academia) using a variety of methods. This data base was received in March 1993.
Principal gravity parameters include Free-air Anomalies and Simple Bouguer Anomalies
(no terrain correction applied). The observed gravity values are referenced to the
International Gravity Standardization Net 1971 (IGSN 71) and the gravity anomaly computation
uses the Geodetic Reference System 1967 (GRS 67) theoretical gravity formula. The
spatial resolution of the data is randomly distributed within the boundaries of Minnesota.
