Topographic Maps of Utah
Topographic maps show the 3-dimensional surface of the earth in 2-dimensions using elevation-contour lines. Contour lines join points of equal elevation above a specified reference, such as sea level. Think of a contour line as an imaginary line on the ground that takes any path necessary to maintain constant elevation.
A topographic map gives direction, location coordinates, scale, and description of features, such as roads, trails, rails, canals, streams, towns, political and geographic boundaries. Symbols on the map represent buildings, water tanks, mines, picnic sites, and other small features not to scale.
Topographic maps are used by a wide variety of people ranging from engineering professionals, emergency responders, historians and outdoor enthusiasts.
