Hello everyone I am trying to find the angle of the way i.e. if i have two ways intersecting at some point then at that point i want to find the angle between the two ways. Can anyone know how i can do this? |

JOSM can show angles when editing - just draw a new overlapping way over the existing ways and look at the status bar. Do NOT upload. |

If you wanted to do it mathematically you would need to have the co-ordinates of at least three points; the one where they meet and the two which will define the lines from the meeting point that you want to find the angle between. You'd then probably also need to know the co-ordinate reference system and perhaps desired projection, though for short lines I doubt this would make much difference (and this is going beyond my level of knowledge but it is to do with spherical geometry in some way). Google finds this and this which relate. |
