CONTOUR LINE Meaning and
Definition
-
A contour line is a term frequently used in cartography and geography to describe a line on a map that connects points of equal elevation above or below a given reference point, usually mean sea level. These lines are often referred to as isohypse lines. Contour lines allow for the representation of the three-dimensional surface of an area on a two-dimensional map.
These lines are essential tools for understanding the topography and relief of a specific region, providing critical information about the shape and height of the land. By connecting points of equal elevation, contour lines allow map users to visualize hills, valleys, mountains, and other landforms. The spacing between the lines indicates the steepness of the terrain; close contour lines indicate steep slopes, while widely spaced lines represent gradual inclines or flat areas.
Cartographers use various techniques, such as surveying or remote sensing data, to establish the heights at specific points across a landscape and later create contour lines based on these values. The lines are typically plotted on topographic maps, which display both natural and man-made features. By interpreting and analyzing contour lines, geographers, hikers, and other users can gain insight into the relief and characteristics of a given area, aiding navigation, land use planning, and scientific research. Overall, contour lines are a fundamental tool in understanding and representing the physical features of the Earth's surface.

Etymology of CONTOUR LINE
The word "contour" comes from the French word "contour" which means "outline" or "shape". It is derived from the Old French word "cun-tur" which is a combination of "cun" (comprising) and "tor" (twist). The term "line" comes from the Old English word "līne" which means "rope" or "thread". Therefore, the etymology of "contour line" suggests that it refers to a line that outlines or shapes something. In cartography and geography, a contour line represents a line connecting points of equal elevation on a map or a three-dimensional surface.
