USGS Topographic Quadrangle Images (1998)

These are images of U.S. Geological Survey topographic maps that we received in 1998. The files have not been updated since that time, and many of the maps are more than 50 years old. For the latest USGS topographic map products, please see the US Topo web site. Newer versions of some of these DRG images are available for free download at the USGS Store.

The USGS refers to these images as Digital Raster Graphics (DRGs).   Use the links on this page to download DRG images in TIFF or MrSID format for use with image viewing or GIS software on your local system.   Use the TopoFinder to view the images on-line.

For more information: see the U.S. Geological Survey – Explanation of DRGs or our MrSID Information page. A legend of USGS topographic map symbols is also available.
