Revised Topographic Quadrangle Maps

(59K, GIF)

The U.S. Geological Survey produces several nationwide series of topographic maps at different scales. Its most detailed national map coverage is the 1:24,000-scale topographic quadrangle series. Minnesota completed once-over coverage in the early 1980s. By the late 1980s, the state's most obsolete maps, in the growing urban areas, were 10 to 25 years old.

Between 1991 and 1996, a cooperative program with the USGS has produced 138 revised 1:24,000-scale topographic maps. Printed revisions are now available 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.

The thumbnail image above shows the riverfront area of downtown St. Paul. It is a small portion of the St. Paul East 1:24,000 quadrangle, which was scanned at 250 dots per inch and has a resolution of 2.4 meters per pixel.
