|Alaska Gravity Data per 2 x 4 min Cell (96)
|This 2’ x 4’ gravity density grid for Alaska displays the distribution of about 1.1
million 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’ x 4’ 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.
