USGS Topographic Maps

Paul V. Galvin Library is a participant in the Federal Depository Library Program, and as such, receives 7.5 minutes topographic maps of the United States from the United States Geological Survey. The depository is receiving electronic versions of these maps, which are distributed in GeoPDF format. These new maps can be searched for in the online catalog of the library's holdings available on the library homepage.

Current editions of maps that were originally distributed to depositories in paper format have been digitized as normal PDF. These and the newer editions, in Geo PDF format, are available for download from the USGS Map Locator, below.

As one of the cornerstones of the U.S. Geological Survey's (USGS) National Geospatial Program, The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data. The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover. Other types of geographic information can be added within the viewer or brought in with The National Map data into a Geographic Information System to create specific types of maps or map views. The National Map is a significant contribution to the National Spatial Data Infrastructure (NSDI) and currently is being transformed to better serve the geospatial community by providing high quality, integrated geospatial data and improved products and services including new generation digital topographic maps.
USGS Map Locator
The USGS Map Locator allows for the download of 7.5 minute U.S. Topographic Maps in a zipped PDF format. It also is handy for use as an index of the maps, so that the ones held in a physical format by the library can be retrieved.
