A topographic map can be easy to read once you know the details. First, look for the map’s scale, which will let you know how much detail the map contains. The scale on any topographic map will tell you how many miles, or fractions of a mile, one inch represents. The smaller the scale, the more detail the map has.

What do the numbers mean on topo maps?
It is found in the top right hand corner of the map (Fig. … The next thing that you should notice on a topographical map are the numbers running all around the outside of the map. These numbers represent two grid systems that can be used to find your exact location. The first is called latitude and longitude.
How do you read slope on a topographic map?
To find the slope of a feature, the horizontal distance (run) as well as the vertical distance (rise) between two points on a line parallel to the feature need to be determined. The slope is obtained by dividing the rise over run. Multiply this ratio by 100 to express slope as a percentage.
How do you read a topographic map for kids?
Try this: If you put your finger on a contour line and follow it around the map, every place your finger is touching is that same elevation. Topographers make reading maps even easier by adding numbers right next to certain lines. Say you’re observing a contour line and the number 12,500 is right on top of it.
How is a cliff shown on a topographic map?
Answer: Cliffs are represented by very close (or sometimes touching) contour lines. … Also note that if a feature such as a small cliff is shorter than the contour interval, then it may not show up on the map.
How do you read elevation contour lines?
You can figure out the elevation of any point by finding the nearest labeled line, counting the number of lines above or below it, multiplying by the contour interval, and adding or subtracting the result from the nearest marked contour line. The more closely spaced the contour lines, the steeper the slope.

What is the contour interval on a topo map?
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.
How do you measure contour lines on a topographic map?
How can you tell if its a hill on a topographic map?
Concentric circles indicate a hill. When contour lines form closed loops all together in the same area, this is a hill. The smallest loops are the higher elevations and the larger loops are downhill.

How do you identify a cliff on a contour map?
On a contour map, the contour lines are very close together or merge into a single line in other words, contour lines overlap. This indicates a cliff.
What does a knoll look like on a topographic map?
Hills, peaks, knolls, mountains: A hill, peak, knoll or mountain is an area of high ground. From a hilltop, the ground slopes down in all directions. A hill is shown on a map by contour lines forming concentric circles. … Knoll = small, rounded natural hill.

Read the number opposite the pointer. That number is your true elevation. If using an optical instrument, just read the number across the horizontal line. That number is your true elevation.
