Factors Affecting the Selection of Contour Interval

Contour lines that are relatively close together indicate a slope that is fairly steep. Contour lines that are further apart indicates a slope that is relatively flat. The area of the map above boxed in orange shows an area that has a fairly steep slope, while the area boxed in purple is a relatively flat area.

Spacing tells us about the slope. Given that the two images are from a map of the same scale, we can state that where the contours are closer together, the slope is steeper. Closer spacing of contours tells us that elevation is changing faster over distance, in other words, a steeper gradient.

DIFFERENCE IN ELEVATION: Point A is on the 580′ contour; point B is on the 520′ contour. The difference in elevation is 60 feet.

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. They’re useful because they illustrate the shape of the land surface — its topography — on the map.

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. Numbers on the lines give the height in feet. (Sea level is zero.) Lines drawn closely together indicate that a slope is steep.

What is another word for contour lines?

A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value.

Also called contour, level curve, level line.

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.
• Concentric closed contours: hills or depression.

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.
