Shoreline maps are the graphic repre­sen­tation of planetable and photogrammetric surveys. The maps contain graphic data relating to the shoreli­ne, alongshore natural and man‑made features, and a narrow zone of natural and man‑made features inland from the shoreline. The original sources of a shoreli­ne map are ground survey data and photographs. Utilizing these sources, photogrammetric map compila­tion techniques, and instruments, cartographers generate shoreline maps, overlays, and associated data. The data are primarily generated to support nautical chart mainte­nance, new nautical chart construction, and hydrogra­phic survey operations.
