I need a way to determine if a polygon's coordines follow a road or not. Is there an attribute for this? I want to list directions, but if the coordinates don't follow a road they are not very accurate. Some coordinates follow roads, but some may not. If any of the coordinates don't follow a road I could just omit displaying directions all together. If I could determine if the path is following a road or not without having to visually look at the map it would be helpful. Does anyone know if there is an attribute or if this is possible? Thanks in advance!
