Earthwork estimates for any type of structure, such as bridges, dams or roads, can be found with the help of contour intervals on a map. A higher contour interval is used for a large area and a small contour interval for a small area.
When a large area is to be mapped onto a small piece of paper, contour intervals are used.
As with counting from one number to the next,.To Knowing how to calculate the contour interval becomes a useful skill.l, start by counting the contour lines from one index line to the next index line. Maps generally count five contour lines from one index line to the next, including the next index line. If the uphill elevation is equal to 1,000 above average sea level and the lowest elevation is equal to 800 above average sea level, the difference in elevation is equal to 200. Index contours are bold or thicker lines that appear at every fifth contour line.
