In honor of the 150th anniversary of the Civil War in 2011, Commerce's Nationasl Oceanic and Atmospheric Administation (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 nearly 400 documents, available free from NOAA’s Office of Coast Survey website.

“People are planning now for their visits to Civil War sites next year, and we want to give them an opportunity to visualize the terrain, ports, and coasts as they were from 1861 to 1865,” said Meredith Westington, NOAA’s chief geographer. “Most people wouldn’t think of turning to NOAA for historical Civil War documents, but the agency has an amazing legacy.”

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. | The Civil War special collection is accessible through a searchable database at www.nauticalcharts.noaa.gov/history/CivilWar. |  Read more
