Do not add additional folds to the maps. A topographic map is a graphic representation of selected natural and man-made features on the earth's surface, plotted to a definite scale. Precise engineering surveys and measurements by the USGS allow topographic maps to show the shape and elevation of the terrain, the network of streams and rivers, and principal works of man. Planning and development projects such as locating highways, selecting industrial sites, locating communication towers, routing pipelines and underground cable. Research projects involving geologic, hydrogeologic, and mineral investigations.
Recreational use includes hunting, fishing, hiking, skiing, boating, and camping.
Topographic maps provide basic tools for orienteering and help us better understand and appreciate the outdoors. The map scale expresses the size relationship between the features shown on the map and the same features on the earth's surface. This could be expressed as 1 inch represents 24,000 inches or 2,000 feet. Adjacent maps of the same quadrangle series can generally be combined to form a single large map. The Depository Map Collection at McIntyre Library holds most of the following national topographic maps.
