Hydrographic data definition
Hydrographic data. ’ means all data obtained from the measurement and description of the physical features of the exclusive economic zone, all internal waters and adjacent terrain, including the depth of the water, configuration and the nature of the topography beneath, the direction and force of currents, heights and times of tides and water stages, location of topographic features and fixed objects for survey and navigation.

Hydrographic data. ’ means information acquired through hydro- graphic or bathymetric surveying, photogrammetry, geodetic meas- urements, tide and current observations, or other methods, which is used in providing hydrographic services. This includes any source data used in the preparation of nautical charts or related products, tide and current predictions, or other nautical products issued by NOS. It does not include data that is unrelated to the production of such products. Hydrographic data is gathered through direct observations, and does not include interpretation of these observations. For example, if NOAA were to contract with a surveying company to perform a hydrographic survey, the sound- ings provided by that company, as well as any other information necessary to evaluate the accuracy of those soundings, would be hy- drographic data. However, a nautical chart containing those sound- ings would not be hydrographic data, because the production of the chart involves data processing, compilation, editing, and other steps after the actual collection of data.
