Water Level Prediction Stations

Water Level Prediction 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 U.S. and international stations at which tide predictions can be generated from historic and active water level stations. According to NOAA, "Tide predictions are a calculation of what the water level will be based on the analysis of data collected at these locations. Harmonic stations generate predictions from harmonic constituents from the data analysis; Subordinate stations generate predictions using time and height adjustments applied to the predictions for a specific harmonic station. CO-OPS offers six-minute and hourly tide/water level predictions 'on-the-fly' for all stations with harmonic constituents. CO-OPS also offers high/low data for all stations in NOAA's published tide and current table."

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.” For other NGDA Content: Esri Federal Datasets
