Nov 8, 2024 · contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. contour line A topographic map with contour lines connecting places that are the same height above sea level. Numbers on the lines give the height in feet. (Sea level is zero.)

Sep 15, 2020 · 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 ...
Aug 10, 2021 · Contour lines are important tools for understanding the terrain and planning routes, whether you’re a hiker, a mountaineer, or a geologist. 1. Understanding Elevation. One of the primary functions of contour lines is to represent changes in elevation. Each contour line on a map represents a specific elevation above sea level, and the lines ...
Contour lines join points of equal and constant values, such as elevation on a topographic map. Learn how to interpret contour lines for mountains, valleys, rivers, gullies and more with examples and diagrams.
Aug 28, 2023 · Contour Lines: Contour lines are continuous lines on a map that connect points of the same elevation. Each contour line represents a specific elevation value, and the interval between contour lines is known as the "contour interval." The spacing between contour lines reflects the steepness of the terrain.

Contour lines also indicate the shape of the terrain. Roughly concentric circles are probably showing you a peak, and areas between peaks are passes. Studying a topo map of a familiar area is a great way to learn how to match terrain features with the contour lines on a map. Index contour lines: Every fifth contour line is a thicker, "index ...
