Distance

Spatial relations include very different situations. Two airports approached by the same airline are connected independently of their distance. In this case, the proximity is given by the flight time or the money spent for the ticket. Two mountain villages located in neighboring valleys separated by a mountain chain may have a common border but are remote in terms of traveling distance. The traveling time to get from one of the villages to the other could be greater than the flight time between the two airports mentioned above. Moreover, the trip depends on the traffic constraints as well.

In the illustration above there is a driving route drafted, containing some obstacles. The relief and the obstacles in the digital elevation model are taken into account by calculating the route.
