How to Calculate Gradient on a Contour Map?

To determine gradient, simply divide the change in elevation between the two points found on your topographic map by their horizontal distance. That’s it!

How to Calculate Gradient on a Contour Map?

Calculating the gradient on a contour map is a useful tool for studying the topography of an area. The gradient is the rate of change of the terrain, and can be used to determine the steepness of a slope, or the rate of change of elevation. Knowing the gradient can help you plan for hikes, outdoor adventures, or other outdoor activities. In this article, we’ll explain how to calculate the gradient of a contour map and provide some helpful tips for using gradient maps.

The first step to calculating the gradient on a contour map is to measure the distance between two points. This can be done with a ruler or a measuring tape. The distance between the two points should be measured in the same units as the contour interval (feet, meters, or some other unit). Once you have the distance between the two points, you can calculate the gradient by dividing the change in elevation by the distance.

For example, let’s say you have a contour map with a contour interval of 10 feet and you measure the distance between two points to be 100 feet. The change in elevation between the two points is 20 feet. To determine the gradient, you would divide 20 by 100, which is 0
