U. S. Shoreline mapping through aerial photography
Since the late 1930s, high-resolution, georeferenced aerial photography for defining the nation’s 95,000-mile shoreline has been a responsibility of the National Geodetic Survey, part of NOAA’s National Ocean Service (NOS). Precision aerial photography is the primary source material used for creating coastal survey maps and digital cartographic files. These data sets, in turn, provide data for producing NOAA nautical charts.

( WEBSITE )
Description
DigBath250 Vector attributed digital bathymetry of UK and adjacent European waters DigBath250 - BGS published map dataset DigBath250 proposed sectors Click on these images to view the relevant map in more detail. Digital maps home The British Geological Survey (BGS) has begun the compilation and production of a vector attributed digital bathymetry of UK and adjacent European waters. The product is known as DigBath250. Its purpose is to provide a regional scale digital bathymetry as a primary dataset for geographic information systems (GIS), mapping and modelling of the seabed and sub-seabed, as well as tidal, current and water column modelling. It is available in standard GIS and CAD formats.
