Overview
These historical coastal images were gathered from numerous sources, scanned on a flatbed scanner, and georeferenced to existing base map data. Many of the historical images are managed by the NOAA National Geodetic Survey. NOAA originally acquired the images to provide a historical context against which to measure historical shoreline boundaries, shoreline erosion rates, impacts of current and future localized storm events, wave-driven inundation from distant storms, and sea-level rise impacts.
