NOAA Office of Coast Survey - Hydrographic Survey Data

bathymetry earth observation marine navigation model oceans oceans


Founded in 1807, NOAA’s Office of Coast Survey is the nation’s first scientific agency and today is responsible for supporting nearly $5.4 trillion in economic activity through providing advanced marine navigation services. The Office of Coast Survey collects and qualifies hydrographic, bathymetric, and topographic data, from NOAA platforms and many other data providers. These data and associated deliverables are posted here for various users to access, including but not limited to the "National Bathymetric Source Program" for incorporation into compilations of the best available bathymetry and NOAA’s National Center for Environmental Information (NCEI) for archival. Qualified data is cleared for application to the navigation products and for public distribution without restriction. Unqualified data is either in queue to be qualified or deemed not to be usable for navigation, but cleared for public distribution according to the data license associated with each file.
