Maps Using Hachure and Contour Methods

Map makers have traditionally used various means to represent the three dimensions of the earth in two-dimensional images. Prior to the nineteenth century, for example, the most common device for indicating relief on a map was through variations of light and shade.

As the use of shading became systematized during the eighteenth and nineteenth centuries, French cartographers referred to these shading lines as "hachures." Hachures represent the slope of the land—the more gentle the slope, the fewer the lines—and the absence of line indicates flat terrain. The illustration on the right side of the document is an example of this system.

The use of contour lines to visually represent different elevations of land came into general use toward the end of the nineteenth century. An early version of a contour map is seen on the left. Simply speaking, a single contour line corresponds to a single elevation of the land. Because the contour line defines a curved surface (the earth), each line encloses a more or less circular area. The total effect is a pattern of concentric lines. The "base" line or datum for most contour maps is sea level, with each line on the map representing a standard distance above or below the base line. As each line signifies an increase or decrease in the land elevation (in this map, 3 feet), one can accurately calculate height by simply counting the lines from the base line (the water's edge in this instance). The slope of any change in the landscape relief can also be determined by noting the proximity of the contour lines to one another. A high concentration of lines tells the map user that the elevation changes sharply, while widely spaced lines indicate a gradual slope.

The two maps of Salem Neck, Massachusetts, surveyed by George W. Whistler (father of artist James A. McNeill Whistler) and William G. McNeill, topographical engineers for the United States Army, were created for a study conducted in 1822 of fortifications in the area. When the Office of Chief of Engineers decided in 1861 to study the feasibility of reconditioning the forts, they referred to these maps and the reports accompanying them.
