USGS Quadrangle Boundaries for Idaho (3.75-Minute)

This data set portrays an index to the U.S Geological Survey (USGS) 3.75 minute digital orthophoto quadrangle images that cover Idaho. These boundaries are sometimes referred to quarter-quadrangles. The University of Idaho Library has at least one 1-meter orthophoto for each quadrangle. The data set was created by merging together source files from the USGS-Boise office and the Idaho Department of Water Resources.
