Abstract
Gravity data assembled for a state gravity map to be published by the Nevada Bureau of Mines are available from the EROS data center on magnetic tape. The first 18 files of the tape contain principal facts for individual data points, organized by 1° x 2° quadrangle. The approximately 71,000 individual data points are from numerous sources including the Defense Mapping Agency data base and U.S. Geological Survey files. Each data record contains geographic position, observed gravity, terrain correction, Bouguer gravity anomaly (p = 2.67 g/crn3 ), and isostatic residual anomaly (Airy Heiskanen, T = 25 km, A/? = 0.4 g/cm3 ). The 19th and 20th data files are 2 km square grids of complete Bouguer and isostatic residual gravity values based on the data in the preceding files. The 9-track magnetic tape is written at 1,600 bytes-per-inch (BPI) in ASCII format with an 80-character record and 4,000-character (50 record) block size.
