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
Minnesota Info
- 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 has developed a New Generation of Topographic Maps, free online in GeoPDF® format. Minnesota's maps became available in 2010.
- The 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 are available for online viewing and download.
