Read this:  Topographical Map Information:

Contour Intervals Since each contour line represents a specific elevation, two different contour are separated by the same difference in elevation (e.g. 20 ft or 100 ft.). This difference between contour lines is called the contour interval. You can calculate the contour interval by following these steps:

a. Take the difference in elevation between 2 bold lines.

b. Divide that difference by the number of contour lines between them.

Imagine that the difference between two bold lines is 100 feet and there are five lines between them. What is the contour interval? If you answered 20 feet, then you are correct (100 ft/5 lines = 20 ft between lines).  100 ÷ 5 = 20 ft between lines.

The legend on the map also gives the contour interval.

Interpreting Contour Maps

How does a topographic map tell you about the terrain? Let’s consider the following principles:

1.The spacing of contour lines shows the slope of the land.Contour lines that are close together indicate a steep slope.This is because the elevation changes quickly in a small area.Contour lines that seem to touch indicate a very steep slope, like a cliff. When contour lines are spaced far apart the slope is gentle. So contour lines help us see the three-dimensional shape of the land.

Look at the topographic map of Stowe, Vermont (Figure above). There is a steep hill rising just to the right of the city of Stowe. You can tell this because the contour lines there are closely spaced. The contour lines also show that the hill has a sharp rise of about 200 feet. Then the slope becomes less steep toward the right.

2. Concentric circles indicate a hillFigure below shows another side of the topographic map of Stowe, Vermont. When contour lines form closed loops, there is a hill. The smallest loops are the higher elevations on the hill. The larger loops encircling the smaller loops are downhill. If you look at the map, you can see Cady Hill in the lower left and another, smaller hill in the upper right.

3.Hatched concentric circles indicate a depression. The hatch marks are short, perpendicular lines inside the circle. The innermost hatched circle represents the deepest part of the depression. The outer hatched circles represent higher elevations (Figurebelow).  Volcanoes craters would be shown this way on a topographical map.

4.V-shaped portions of contour lines indicate stream valleys. The “V“ shape of the contour lines point uphill. There is a V shape because the stream channel passes through the point of the V. The open end of the V represents the downstream portion. A blue line indicates that there is water running through the valley. If there is not a blue line the V pattern indicates which way water flows. In Figure below, you can see examples of V-shaped markings. Try to find the direction a stream flows.

The top of this drawing is a topographical map showing the hills that

are illustrated at the bottom.

On this map, the vertical distance between each contour line is 10 feet.
