NOS Hydrographic Surveys Collection

National Geospatial Data Asset (NGDA) NOS Hydrographic Surveys

1950s smooth sheet

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record. Survey types are B: Hydrographic EEZ Surveys; D: Discovery Surveys; H: Hydrographic Surveys; F: Field Edit Surveys; W: Non-NOS Hydrographic Surveys.

Distribution Formats	Bathymetry Attributed Grid (BAG) File Specification: Bathymetric Attributed Grid (BAG) is a non-proprietary file format for storing and exchanging bathymetric data developed by the Open Navigation Surface Working Group. BAG files are gridded, multi-dimensional bathymetric data files and is the standard NOS hydrographic data file for public release. Geospatial Portable Document Format (GeoImage) File Specification: Geospatial Portable Document Format (GeoImage) is a layered geospatial PDF. This image file contains several layers including: a combined bathymetric surface, a survey scale set of soundings, a large scale raster nautical chart, latitude/longitude graticule, title block, and an acoustic imagery mosaic (if available). The image is also geographically referenced, allowing users to locate features, measure distances and angles, and select specific layers of interest ASCII XYZ TIFF PDF Generic Sensor Format (GSF) Multi-resolution Seamless Image Database (MrSID)

General Documentation	Metadata Landing Page NOS Hydrographic Survey Data Home Page Home page for digitized data from smooth sheets of hydrographic surveys completed between 1837 and 1965, and from survey data acquired digitally on NOS survey vessels since 1965. Over 76 million soundings from over 6,600 surveys are included. NGDC has developed an interactive map and data discovery tool, the Bathymetry Map Service, and a text-based search engine, the Hydrographic Survey Text Search, which enable rapid data discovery and download.

Purpose	These hydrographic data are made available to the public for a wide variety of uses, such as sea-bottom characterization, habitat classification, coastal studies, boundary issues, and tsunami forecasting. These data are not intended to be used for navigation. Nautical charts produced and certified by NOAA should be used for navigation purposes.
