What is meant by the contour "interval" on a topographical map?

Answer 1

Contour Interval - The vertical difference in measurement units such as meters or feet, between successive contour lines on a contour map.

Answer 2

Ha! I just taught this lab. Weird.

The contour interval is the amount in feet or metres or whatever the unit of measure is between contour lines. Remember, contour lines connect points of equal elevation. Usually on a standard contour map, only the index contours are labeled and they are drawn bolder than the others. But each line, light or bold, represents an elevation.

So say you have 2 index contours one labeled 400 units and one labeled 500 units. There are 4 contour lines between them. Count from the line next to 400 to the 500 line. That's 5 lines. 500 - 400 = 100, 100/5 = 20. So the contour interval is 20 units.

On most maps, the contour interval is also given.

Answer 3

The contour interval is the amount in feet or metres or whatever the unit of measure is between contour lines. Remember, contour lines connect points of equal elevation. Usually on a standard contour map, only the index contours are labeled and they are drawn bolder than the others. But each line, light or bold, represents an elevation.contour lines are the imaginary lines joining all points/places having the same height.contour intreval is the diffrence in height between 2 successive contour lines.usually it is 20 m for indian topo.

Answer 4

it is the vertical distance between two contour lines(difference in level)
