| NGDC manages a wide variety of geophysical data including trackline and survey data
as two distinct types. Multibeam data tend to bridge these data models depending on
scale and track pattern. One of NGDC’s geophysical data holdings is the MBBDB system
which has been assembled as an online data base using existing Commercial and Government
Off-The-Shelf (COTS and GOTS) software systems: ORACLE, ArcGIS, Generic Mapping Tools
(GMT), MB-System, and Autochart. The MBBDB is a world wide compilation of mulitbeam
bathymetric data.
