Hello! I used the open source call api "https://graphhopper.com/api/1/route?point={lats[i]},{longs[i]}&point={lats[j]},{longs[j]}&profile=bike&locale=de&calc_points=false&key=##
to get the distances between multiple points.
I would like to know what kind of metric is behind these calculations, is it Manhattan distance?
No, it is the distance of the route calculated by GraphHopper. Hard to say in a few words, but it is the distance of the route we recommend for bikes going from A to B. You can visualize the route on GraphHopper Maps, e.g. Graphhopper Maps
Hello, thank you for your answer. My question was more focused on the mathemical formula used behind, if it’s known which metric/formula is used to calculate these distances
