Calculate the Slope and Contour Intervals Between Two Spot Elevations
You supply the horizontal distance between two points and the elevations of both end points, and I’ll show you the slope between those two points. If there are any contour lines in the interval between the two points, I’ll also show a table giving the horizontal distance from the lower endpoint to the point where each contour line crosses the interval.
Distance between endpoints:
Elevation Difference Between Contours:
Endpoint Elevations:
