2020年9月15日 · A contour line is a curve that joins points of equal value. In cartography, contour lines join the points of equal elevation above a given standard level like the mean sea level. A contour map is a map to illustrate the topographical features of an area using contour lines. It is often used to show the heights, slopes and depths of valleys and ...

2025年2月17日 · There are three primary types of contour lines found on most topographic maps: intermediate contours, index contours, and supplementary contours. Each serves a specific purpose in depicting the terrain accurately.

Contour lines are curved, straight or a mixture of both lines on a map describing the intersection of a real or hypothetical surface with one or more horizontal planes. The configuration of these contours allows map readers to infer the relative gradient of a parameter and estimate that parameter at specific places.
