NOAA's Shoreline Survey Maps - Raster NOAA-NOS Shoreline Survey Manuscripts that define the shoreline and alongshore natural and man-made features

NOS coastal survey maps (often called t-sheet or tp-sheet maps) are special use planimetric or topographic maps that precisely define the shoreline and alongshore natural and man-made features, such as rocks, bulkheads, jetties, piers, and ramps. These maps typically range in scale from 1:5,000 to 1:40,000. The first shoreline survey was completed in 1834. Since the early 1800's, over 12,000 coastal survey maps have been constructed. These maps permanently reside within the offices of the National Archives and Records Administration (NARA).
