Service Description: A map service showing the location and coverage of National Ocean Service (NOS) Hydrographic Surveys. The NOS Hydrographic Database (NOSHDB) and Hydrographic Survey Metadata Database (HSMDB), both maintained by NOS and NOAA's National Centers for Environmental Information (NCEI), provide extensive survey coverage and ISO metadata of the coastal waters and Exclusive Economic Zone (EEZ) of the United States and its territories. The NOSHDB contains 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. Data products from NOS surveys, including Bathymetric Attributed Grid (BAG) files, Descriptive Reports, smooth sheet images, survey data images, textual gridded data, and geo-referenced sidescan sonar mosaics, ISO metadata, and survey statistics are available for download from NCEI.
This service is available as a
dynamic map service and a
tiled map service. The tiled map service draws faster, and is visible from global scales, to zoom level 10 (approx. 1:577,000 scale), but does not have the ability to toggle sublayers on/off.
Modern surveys provide gridded data in the form of bathymetric attributed grids (BAGs). Please see the following services for mosaics of the BAG data:
Or view a
combined map with the image services and survey polygons.
Layers available in this map service:
- Layer 0: Surveys with BAGs available (Bathymetric Attributed Grids).
- Layer 1: Surveys with digital sounding data available for download (including those with BAGs).
- Layer 2: Surveys without digital sounding data available for download (hidden by default).
- Layer 3: Detailed BAG footprints.
The
NCEI Bathymetric Data Viewer (
NOAA GeoPlatform entry) can be used to search and display these data.
