Historical Topographic Maps – Preserving the Past | U.S. Geological Survey

Legacy U.S. Geological Survey Topographic Maps 

The Historical Topographic Map Collection, or HTMC, provides a comprehensive digital repository of all scales and all editions of U.S. Geological Survey (USGS) printed topographic maps that is easily discovered, browsed, and downloaded by the public at no cost. 

In 2011, the USGS National Geospatial Program began publishing scans of 1:250,000-scale and larger topographic maps printed between 1884, the inception of the topographic mapping program, and 2006, when the final maps created using traditional cartographic methods and lithographic printing processes were published. Many of these maps are no longer available for distribution in print. 

Today, the HTMC contains over 185,000 high-resolution, georeferenced digital files, with accompanying metadata, representing these legacy maps.
