Absolute gravity database
Information about developpment and structure of the global Absolute Gravity data base
The new database for absolute gravity (AG) measurements has been implemented at BGI and BKG in 2007 and is operational for storing absolute gravity data either in the form of metadata or as detailed measurement results. The database contains up to 355 sites in early 2010.
