|PR/VI Gravity Data per 2 min Cell (96)
|This 2’ gravity density grid for Puerto Rico and the Virgin Islands displays the distribution
of about 26,000 terrestrial and marine gravity data held in the National Geodetic
Survey gravity data base in July 1996. These data were augmented by gravity data contributions
from NGA (former National Imagery and Mapping Agency (former Defence Mapping Agency))
and by satellite altimeter-derived marine gravity anomalies computed by Sandwell and
Smith (1996). The values show the number of gravity data contained in a given 2’ cell.
Additional information is available at http://www.ngs.noaa.gov/GEOID/We are particularly
grateful to NGA (former National Imagery and Mapping Agency) for their assistance
and their data contributions.
