USGS Topographic Map Series in the Map & Aerial Photography Library

The U.S. Geological Survey (USGS) began systematically mapping the United States of America in the 1880s. Over time, they produced topographic maps of all US territories at increasingly detailed scales. Maps were updated as needed. For a history of the Mapping program see A 125 Year History of Topographic Mapping and GIS in the U.S. Geological Survey 1884-2009, Part 1, 1884-1980 and  A 125 Year History of Topographic Mapping and GIS in the U.S. Geological Survey 1884-2009, Part 2, 1980-2009.

The USGS stopped printing and distributing topographic maps to libraries in 2009 when they switched to US Topo, which allows for free download of digital copies and a print on demand system.

Current Topographic Maps

The most recent versions printed in the traditional manner are available for self-service in the Map Library on the first floor of Knight Library. For the most detailed scale (1:24,000 that covers an area measuring 7.5 minutes of latitude by 7.5 minutes of longitude, also known as 7.5-minute topo quad[rangle] maps), we have complete coverage for Oregon, Washington, Idaho, Nevada, California, and Hawaii. We also have complete coverage for Alaska, which was mapped in less detail, due to it’s size. We have national coverage at the 1:100,000 scale (1 degree latitude by 30 minutes longitude) and 1:250,000 (1 degree latitude by 2 degrees longitude). All three series also may be downloaded as PDFs directly from the USGS website.

Historic Oregon Topos

In addition, we have historic collections of topographic maps of Oregon. The links below lead to inventories of our paper collection. To use the older maper maps, contact the Map and Aerial Photography Library.

Historic Metro Series

The Map & Aerial Photography Library has an extensive collection of older USGS topographic maps of US Cities. Please contact the Map & Aerial Photography/GIS Librarian for more information.
