Present Status

In 2002, a new server configuration was implemented replacing the GIF and TIFF image server. In order to accommodate the large color file sizes of the 1900s historical maps and charts, a Mr. Sid Image Server was added and all existing images were transferred to the LizardTech Mr. Sid Compression Format (at 50:1) This technology allows the user to browse, pan, and zoom into the images through standard internet browser software and the ability to download images in the Mr. Sid Compression Format to their desktop systems for later viewing via a free download of a Mr. Sid Viewer. A new, dynamic catalog replaced the old static catalogs and allows for user defined searches by map or chart number, year, type, and description. Currently, over 14,000 images are available for free downloading at the site.

The Collection is available for free usage by the general public, other Federal, State or Local agencies, and educational institutions. If the images are used in a publication, presentation or exhibit, the Coast Survey requests an appropriate credit line be included such as "From the Image Archives of the Historical Map & Chart Collection/Office of Coast Survey/National Ocean Service/NOAA."
