Measurement of Road Distance

Explore the process of calculating road distances using OpenStreetMap, delving into practical applications and hands-on learning.

We'll cover the following

We’ve calculated the distance on the surface of the Earth. Even though the geodesic method is closer to reality than the straight-line model, there’s still potential for optimization. Since the salesperson is supposed to drive the distance by car, we need to calculate the real driving distance instead of the surface distance.

The distance (using the geodesic method on WGS-84 ellipsoid) between the two stores, A and B, is 11.3 km (or approximately 7 miles). But how long would it take if we went by car? And how long would we need to cover this distance? We’ll use OpenStreetMap’s API to answer these questions.
