In honor of the 150th anniversary of the Civil War in 2011, National Oceanic and Atmospheric Administration (NOAA) has assembled a special historical collection of maps, charts, and documents prepared by the U.S. Coast Survey during the war years. The collection, “Charting a More Perfect Union,” contains over 400 documents, available free from NOAA’s Office of Coast Survey website.
Coast Survey’s collection includes 394 Civil War-era maps, including nautical charts used for naval campaigns, and maps of troop movements and battlefields. Rarely seen publications include Notes on the Coast, prepared by Coast Survey to help Union forces plan naval blockades against the Confederacy, and the annual report summaries by Superintendent Bache as he detailed the trials and tribulations of producing the maps and charts needed to meet growing military demands.
