What is contour line drawing?
Put simply, a contour line drawing is an “outline drawing,” that uses no shading. A contour drawing is done when the artist looks intently at the EDGES of an object, but rarely looks at the paper while the pencil moves.
Why is contour line drawing important?
Contour drawing forces you to really notice and work to replicate the outline of an object. It trains your hand to follow what your eye sees. Start by spending about half your time looking at the object and half your time looking at your paper, and gradually work your way up to looking at the object 90% of the time.
What are 3 types of contour lines?
There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line.

What are the types of contour?
There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. This tells you the elevation above sea level.
What are the characteristics of contour lines?
Characteristics of Contours
- Must close on themselves, on or off the map.
- Perpendicular to the direction of max.
- Slope between them is assumed uniform.
- The distance between them indicates the steepness of the slope, gentle or steep.
- Irregular signify rough, smooth signify gradual slopes.
What are 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 is contour drawing in civil engineering?
An imaginary line on the ground surface joining the points of equal elevation is known as contour. • In other words, contour is a line in which the ground. surface is intersected by a level surface obtained by joining points of equal elevation. This line on the map represents a contour and is called contour line.
What Colour are contour lines?
brown
Topographic contours are shown in brown by lines of different widths. Each contour is a line of equal elevation; therefore, contours never cross. They show the general shape of the terrain.

What are the 5 Rules of contour lines?
2.10: Rules of Topographic Maps
- Contour lines always separate points of higher elevation (uphill) from lower elevation (downhill).
- Contour lines never cross or intersect.
- Contour lines never split or divide.
- Contour lines always close to form a shape, usually an irregular circle.
What are called contour lines?
A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line.
