What is contouring and contour line?

In cartography, a contour line (often just called a “contour”) joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

Why are contour lines useful?

The purpose of contour lines is to represent the tridimensional shape of the terrestrial surface on a bidimensional map. Contour lines are the intersection of an horizontal plane parallel to the reference level and the topographical surface to describe. Consequently: Contour lines are always closed curves.

What do you mean by contouring?

Contour is the outline or shape of something. … Contour comes from the Italian contorno meaning “to draw a line,” which is precisely what you are doing when you trace the contour of something.

On the other hand, contour is used to enhance and highlight the natural features of the face – like its shape – and makes it distinct.

How many methods are there for contouring?

How do contour lines work?

Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant. Contour lines show elevation and the shape of the terrain. … In order to keep things simple, topographic maps show lines for certain elevations only.
