GEODAS (GEOphysical DAta System) is an interactive database management system developed by the National Geophysical Data Center (NGDC) for use in the assimilation, storage and retrieval of geophysical data. The GEODAS software is being used with several types of data including marine trackline geophysical data, hydrographic (bathymetric) survey data, aeromagnetic survey data, multibeam bathymetric data, […]
NOAA Electronic Navigational Charts (ENCs) have been developed to support safe navigation in U.S. waters and are available for free download at NOAA ENC.
Map products include georeferenced true-color images derived from IKONOS satellite imagery, estimated bathymetry (in meters), benthic habitat cover, and detailed benthic habitat classes.
The NOS Data Explorer serves as a portal to obtain NOS spatial data.
Allows users to view and download all available land cover and change data collected through the Coastal Change Analysis Program
