    dct:description "The gravity station data total 3064 records. This data base was received in April 1997. Principal gravity parameters include Free-air Anomalies which have been adjusted to the International Gravity Standardization Net 1971 (IGSN 71), and the gravity anomaly computation uses the Geodetic Reference System 1980 (GRS80) theoretical gravity formula. The data are randomly distributed within the boundaries of Portugal." ;
