Marble is able to calculate route for: 1) bicycle 2) car 3) other vehicle but it can't calculate precise distance between chosen points! I don't need route for a bicycle or for a car (I live in Russia), but I need to calculate distance for a plane. Why is there no such feature? Looking forward to seeing the feature in the next release, Evgeniy
Please see http://docs.kde.org/stable/en/kdeedu/marble/measure-distances.html for instructions how to measure distances.
