Published Benchmark Stations

Published Benchmark Stations This feature layer, utilizing National Geospatial Data Asset (NGDA) data from the National Oceanic and Atmospheric Administration, displays the Center for Operational Oceanographic Products and Services (CO-OPS) locations of all water level stations, in the United States and elsewhere, that have published bench mark sheets. According to NOAA, "The published tidal bench mark sheet is a final documented compilation of tidal datum elevation and tidal bench mark information based on the accepted tidal datums computed from tide station observations."

Per the Federal Geospatial Data Committee (FGDC), Water - Oceans & Coast is defined as "features and characteristics of salt water bodies (i.e. tides, tidal waves, coastal information, reefs) and features and characteristics that represent the intersection of the land with the water surface (i.e. shorelines), the lines from which the territorial sea and other maritime zones are measured (i.e. baseline maritime) and lands covered by water at any stage of the tide (i.e. Outer Continental Shelf ), as distinguished from tidelands, which are attached to the mainland or an island and cover and uncover with the tide."
