        abstract:  The gravity station data (1,633,499 records) were gathered by various governmental organizations (and academia) using a variety of methods. This data base was received in March 1999. Principal gravity parameters include Free-air Anomalies and Simple Bouguer Anomalies (with terrain correction applied only in areas where substantial variations in local topography exist). The gravity station data has been adjusted 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 data are randomly distributed within the boundaries of the U.S., Alaska and Hawaii.
        purpose:  To provide easy access to global and regional gravity data and related models for scientific studies.

                attributeType:
            descriptor:  The terrain correction is an adjustment to the simple Bouguer correction that accounts for variations in terrain above and below the elevation of the gravity station at distances away from the point of measurement. Terrain below and above the level of the theoretical horizontal slab used to make the simple Bouguer correction results in a mass deficiency or excess that always yields an erroneously low gravity measurement. As a consequence, the terrain correction is always added to the simple Bouguer correction. The total terrain correction is the sum of the inner and outer zone terrain corrections described above.

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Horizontal Positional Accuracy Report
            evaluationMethodDescription:  Horizontal accuracy varies from source contributor to source contributor. However, horizontal positions are usually taken from topographic maps of the area being surveyed. Accuracy may range up to +/- 100 feet.

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Vertical Positional Accuracy Report
            evaluationMethodDescription:  Vertical accuracy varies from source contributor to source contributor. However, vertical positions are usually taken from topographic maps of the area being surveyed, monumented benchmark locations, or they are determined by the use of the Global Positioning System (GPS). Accuracy may range from meters to centimeters or better.

            nameOfMeasure:  Quantitative Attribute Accuracy Assessment
            measureDescription:  Statistical analysis.
            evaluationMethodDescription:  Gravity data values are the result of the measurement of small variations in the gravitational field of the earth. The magnitudes and ranges of these variations are well known in the potential field discipline.
