What are contour lines examples?

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.

What are the uses of contour lines?

These contour lines are an important way of showing the rise and fall of the land on a map. Contour lines show all the places that are the same height above sea level. They also tell us about the slope of the land. On a steep slope, the lines are close together.

What are contour lines used for in art?

A contour line defines the outline of a form, as well as interior structure, without the use of shading. A fundamental basis of drawing, contour lines are usually the first technique children adopt to draw people, houses, and trees.

Why are contour lines important in art?

The purpose of contour drawing is to emphasize the mass and volume of the subject rather than the detail; the focus is on the outlined shape of the subject and not the minor details.

How are contour lines used in construction?

It is the line on a plan or map that represents those points that have the same height, that is to say, they have the same altitude, in relation to a reference plan. They must not intersect or coincide, except in vertical walls and cornices, as the higher they are the less developed they are.

What is contour write its characteristics and uses?

Contours show distinct characteristic features of the terrain as follows: i) All points on a contour line are of the same elevation. vii) Closed contour lines with reducing levels towards the centre indicate pond or other depression. viii) Contour lines of ridge show higher elevation within the loop of the contours.
