Name: Datums_Stations

Display Field: name

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Layer represents the geographic location of all water level stations at which datums have been calculated. For marine applications, a datum is a base elevation used as a reference from which to reckon heights or depths. It is called a tidal datum when defined in terms of a certain phase of the tide. Tidal datums are local datums and should not be extended into areas that have differing hydrographic characteristics without substantiating measurements. In order that they may be recovered when needed, such datums are referenced to fixed points known as benchmarks. The "Present Epoch" is from 1983-2001 and includes the latest datums available. The "Superseded Epoch" is from 1960-1978 and has been replaced by the "Present" datums, or was not replaced due to insufficient data. More information can be found at http://tidesandcurrents.noaa.gov/datum_options.html and http://www.tidesandcurrents.noaa.gov/publications/Computational_Techniques_for_Tida l_Datums_handbook.pdf
