        abstract:  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.
        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.

        abstract:  This image service provides a seamless mosaic of high-resolution quality-controlled seafloor elevation from NOAA / National Ocean Service (NOS) Hydrographic Survey Bathymetric Attributed Grids (BAGs) in U.S. coastal waters. Many near-shore areas have been mapped at high resolution (often 1 meter or better). The depths are usually relative to Mean Lower Low Water (MLLW) datum. 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. Current versions of the BAG file contain position and depth grid data, as well as position and uncertainty grid data, and the metadata specific to that BAG file, providing end users information about the source and contents of the BAG file. This service has a server-side function available. This can be selected in the ArcGIS Online layer using "Image Display", or in ArcMap under "Processing Templates": None: Provides depth values in meters. Usually relative to mean lower low water (MLLW), except for some rivers/lakes (see the survey metadata for details); ColorHillshadeBAG: an elevation-tinted hillshade visualization. This is also available as a separate tile layer (faster to draw): https://noaa.maps.arcgis.com/home/item.html?id=7ca0a68d6fd8480cb83c89173ab9d814. The elevations/depths are displayed using this color ramp: http://maps.ngdc.noaa.gov/viewers/bathymetry/images/bag_hillshades_color_scale.png

                description:  REST endpoint for Bathymetric Attributed Grid (BAG) Color Shaded Relief "Subsets" ArcGIS Image service. Allows access to the underlying images; allows subsets using a definition query; maximum of 80 rasters displayed at a time. When using the subsets version in ArcMap or the JavaScript API, etc., a definition query can be used to display groupings of images. Example definition query to view all the BAGs for a single NOS survey H12003 off Maryland/Virginia: "Name LIKE 'H12003%'".

        abstract:  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. Layers available in the map service: Layer 0: Surveys with BAGs available (Bathymetric Attributed Grids); Layer 1: Surveys with digital sounding data available for download; Layer 2 (hidden by default): Surveys without digital sounding data available for download. Layer 3: Detailed BAG footprints.
