Does OSM data contain information relative to the center-line of a road or a way to determine it? In the US and elsewhere some roads change back and forth to/from dual carriage ways or are dual carriage ways for their entire length. Is there a way to determine a road "center line" from the OSM data, i.e., a single line tracking the road? Regards, Jim asked 02 Nov '12, 12:41  obrienj |
One Answer:
A typical road is represented by a single osm way, which should already follow the centerline of the road. Dual carriageways are often represented by two osm mays (tagged as oneway=yes), but the principle is the same. If you want to go into more details, have a look at the lanes tag and tag suffix. But there are a lot of ways that lack this detailed info (especially the suffix ones, as it is a fairly new scheme). answered 02 Nov '12, 14:05  Vincent de P... ♦ |
