Topographic Maps

Topographic maps portray elevations and geographic positions for both natural and man-made features. These are often used as a basic reference map. 

Topographic quadrangles, also known as topo quads or "topos", are typically produced for a region or nation using a standard set of map scales and dimensions. These sets may be referred to by their scale or by the number of minutes or degrees of latitude/longitude which each sheet covers. For example, USGS topographic quadrangles at a scale of 1:24,000 are also referred to as 7.5 minute quads.

Print collection at Morris Library

The Maps collection in the lower level includes 7.5-minute topographic maps of Delaware, Maryland, New Jersey, and Pennsylvania. Please ask at the Student Multimedia Design Center desk for assistance. The earlier 15-minute topographic maps of these states are housed in Special Collections.

Delaware has unique topographic map products, linked from the State Map & Data tab.
