Relief

From the earliest maps to the present, mapmakers have relied on a variety of methods, symbols, and designations to address the challenging task of illustrating the three-dimensional aspects of a location using a flat, two-dimensional map.

AACR2 recognizes many different ways of portraying relief, including

pictorial hachures
landform drawing gradient tints
rock drawing form lines
contours spot heights
soundings hypsometric tints
bathymetric tints hill shading
satellite imagery

The forms of relief used most often on early North Carolina maps are pictorial, hachures, and soundings. Beginning in the mid to late 19th-century, North Carolina mapmakers began to use additional methods for showing relief, including contours, spot heights, and hill shading. The examples below show illustrations of each method.



"Relief Shown Pictorially"

On many early maps of North Carolina and the southeast, topography is illustrated simply by drawings of mountains and hills. Early explorers were clearly aware that there was a large mountain chain several hundred miles to the west of the coast, but the maps they produced show that there was at the time very little additional information.
