Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. The actual contour interval of a map depends upon the topography being represented as well as the scale of the map.

A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a topographical map.Mar 8, 2017
To calculate contour interval, we need to divide the difference in elevation between the index contour lines by the number of contour lines from one index contour line to the next. For example, if the distance 200 is divided by the number of lines, where the number of lines is 5.
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.
Contour intervals tell you the change in elevation between any two contour lines. You can find the contour interval in the map key, usually located underneath the scale of the map at the bottom center.Feb 5, 2022
A contour line on a topographic map connects points of equal elevation. The change in elevation from contour line to contour line is called the contour interval.
Contour Index are bold and thicker lines that appear at an interval of every fifth contour line. The increase in the number associated with specific contour lines shows the elevation of the terrain is also increasing and vice versa.

The shape of the contour lines can indicate the shape of the landforms in a specific area. For example, concentric circles show a peak, with the smallest circle marking the summit.
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. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing.
Topographic maps are an important tool because they can represent the three-dimensional landscape in two dimensions. A person who can read a map from the top can discover the location of peaks, valleys, mountain intervals, and saddles, among other land features.
A contour map consists of contour lines for a given geographic region. To keep the contour map simple and easy to read, not all contour lines are marked with their elevation reading. These marked or labeled lines are known or called Contour lines of the index.
To combine a topographic map with the surrounding landscape, which will allow you to identify features such as mountains and rivers, it is important to ensure that the map is oriented correctly.
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.
Index contours are bold or thicker lines that appear at every fifth contour line. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing. If the numbers associated with the contour lines are decreasing, there is a decrease in elevation.
Contour lines are critical to understanding the elevation profile of your terrain or a particular land formation.
This tells you the elevation above sea level. 2. Intermediate lines are the thinner, more common, lines between the index lines. They usually don't have a number label.
Topography is the study of geographical features on a landscape. A map with contour lines on it is called a topographic map. Topographic maps use a combination of colors, shading and contour lines to represent changes in elevation and terrain shape. Essentially, topographic maps represent the three-dimensional landscape ...
Of course, paper maps aren’t the only topographic tool out there. Smartphone apps and computers can provide any topographic map you may need quickly and accurately, even beyond the reach of wifi and cell signals.
