Topographic Maps for Minnesota
The U.S. Geological Survey produces several nationwide series of topographic maps at
different scales: 1:24,000; 1:100,000; and 1:250,000-scale. The most detailed national map coverage is the 1:24,000-scale
topographic quadrangle series. These maps show many features in addition to
the brown elevation lines that show topography.
Scanned (digital) topographic maps are called "Digital Raster Graphics" or
DRGs. One version of DRGs are individual files that include the outside or
"collar" information; "collarless" versions clip off the outside information in
order to create seamless files.
About Topo Maps
USGS Topographic Maps (USGS)
This website gives an introduction to the history of USGS topographic
mapping from 1879 to the present as well as general information about
topographic mapping, maps of the USGS, Digital Raster Graphics (DRGs),
topographic map revision, symbols, and mapping standards.
- Original maps: Minnesota had completed once-over 1:24,000-scale coverage in the early 1980s.
- Updated maps: Between 1991 and 1996, a cooperative program with the USGS
produced 138 revised 1:24,000 topographic maps for the Twin Cities, Duluth, St.
Cloud, Moorhead, Mankato, Rochester, Red Wing, Winona, a few other cities,
the growing suburban area of the Twin Cities-St. Cloud corridor and the
Brainerd lakes area. See map.

USGS Historical Quadrangle Scanning Project is scanning and
georeferencing all scales and editions of topographic maps published
by the USGS since the inception of the topographic mapping program
in 1884. The maps will be available for online viewing and
