Collection of Observed Gravity Values, Absolute Gravity Measurements, Grids and Other
Derived Summary Data |
The National Geophysical Data Center (NGDC) of NOAA, in cooperation with the National
Geodetic Survey of NOAA, have published a Gravity CD-ROM containing observed and derived
gravity measurements. Contributions to this data compilation include many national
and international organizations, in both academia and government. The compact disc
contains almost 620 Mbytes of data, partitioned into 1486 files. Approximately 25
percent of the data are observed values -- regional station data collections (separated
primarily by contributors) and absolute gravity measurements. Grids and other derived
summary data sets represent another 65 percent of the data. The remaining 10 percent
of the disc contains geopolitical base map reference data and software. |
