USGS Resources for Working with Topographic Maps
Downloading and Purchasing USGS Topographic Maps
Download free digital topographic maps in a GeoPDF format by going to the USGS Store and clicking on "Map Locator & Downloader". Users have the option of selecting two different kinds of topographic maps. Both can be downloaded in a digital format for free or ordered as a paper product:
- US Topo Maps - The same 7.5-minute quadrangles as our historical topographic maps, but generated entirely by computer. Updated every three years, these maps have different layers that can be turned on and off.
- "Historical" topographic maps - These are high-resolution scans (400 ppi to 508 ppi) of existing paper maps. They are available at all scales and in all editions.
To browse popular thematic maps, go to the USGS Store and click on "Education Products"
