the points on the map not show the distance. they only stay on the border to show where to go to arrive the location. but if the in range of the map, the are 1000 steps over the location, and hey chose, maby with a key, the location(building , ship or coardinates)
i think it the relativ vector must be xy-relativ cut to be maximal dist of the map view. with a 2d map, they can be uncorect coardinates by the scaling, because his maps are maby very huge
