As a special service to the mapping community, Maptech is proud to host this collection of historic USGS topographic maps. This ongoing project is headed by historian Christopher Marshall and compiled through the efforts of many individuals. We are honored to be the stewards of this fine collection, making it available to all via the World Wide Web.
For a discussion on the evolution of USGS maps, please check out the section on "Historic Topographic Maps". Select "About the Collection" for information on how you can help expand this library. Maps are scanned and processed by volunteers who share an interest in historic maps. Maptech sponsors their efforts by providing free web space for this collection.
Of course, those seeking speedy access to current USGS topographic maps should investigate Maptech's Terrain Navigator. Terrain Navigator combines regional collections of USGS topographic maps on CD-ROM with powerful PC navigation software for 2-D and 3-D viewing, customizing, printing and GPS use.
