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 Geophysical Data Center (NGDC), 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 NGDC.

All Layers and Tables

Layers: Description: A map service displaying the footprints of NOS Hydrographic Surveys. Layer 0: Surveys with BAGs (Bathymetric Attributed Grids). Layer 1: Surveys with digital data available for download. Layer 2 (hidden by default): Surveys without digital data available for download. The National Ocean Service (NOS) Hydrographic Data Base (NOSHDB) and Hydrographic Survey Meta Data Base (HSMDB), both maintained by NOS and NGDC, provide extensive survey coverage and Federal Geographic Data Committee (FGDC) with Remote Sensing Extensions (RSE) 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 BAG files, Descriptive Reports, smooth sheet images, survey data images, textual gridded data, and geo-referenced sidescan sonar mosaics, FGDC/RSE metadata, and survey statistics are available for download from NGDC. The corresponding map service showing color-hillshade visualizations of the BAGs (Bathymetric Attributed Grids) is available here: http://maps.ngdc.noaa.gov/arcgis/rest/services/web_mercator/bag_hillshades/MapServer. For more information about NOS Hydrographic Survey data available at NGDC, please see: http://ngdc.noaa.gov/mgg/bathymetry/hydro.html
