Topographic Map Gradient Calculator. Step one: Find the two points you will be working with. However, the application of slope calculation can seem a little more complicated. The ability to read and interpret topographic maps is considered a basic skill for all geoscientists and geoscience students. Determine the vertical distance by identifying the elevation values for each contour line you have selected. Topographic maps are used to understand the shape of the land, whether a slope will fail, how glaciers are changing, and geologic history, among many other things. Then measure the horizontal distance between these two contour lines by using a ruler.
Topographic Map Gradient Calculator. This elevation grade calculator determines and expresses, in four different ways, the slope of an earthen surface. On topographic maps, gradient is usually calculated with reference to two points. Understand what map projection is, learn how scales work in map projection, and read the main types of map projections. This typically involves finding two nearby points of elevation, for example, a peak and valley, or a higher and lower point. Topographic maps are used to understand the shape of the land, whether a slope will fail, how glaciers are changing, and geologic history, among many other things. A gradient is the difference in elevations between two locations divided by the distance between the two locations. Topographic Map Gradient Calculator.
Then measure the horizontal distance between these two contour lines by using a ruler.

Topographic Map Gradient Calculator. Determine the vertical distance by identifying the elevation values for each contour line you have selected. You can also find the elevation of a single location, simply enter the address you want the elevation measure. @MatricRewrites Explanation on how to calculate the gradient on a topographical map. Additional science videos and resources at: https://science.glide.page Subscribe. Topographic maps include contour lines that indicate elevation changes, which makes them a great way to measure the steepness, or gradient, of an area. Let's call them point A and point B. The Calculate Slope tool generates a surface displaying slope, using elevation data.
