I don't believe that the relations will covey the state / properties of the road as a way would. > way way back in 2015, this section of the OHM wiki page got set up: > https://wiki.openstreetmap.org/wiki/Open_Historical_Map#Short-term_plans the > link to OHM/Tags was never filled in in the 4+ years since. i think it's high > time we started describing how people are tagging to reflect historic > features and dating. i certainly am working through a lot with my stuff, and > the method Leon is using could certainly go in as well, as examples of > experiments as this is largly experimental at this time. I've checked, the page isn't locked. Why don't you start documenting how you are tagging roads? -R _______________________________________________ Historic mailing list [email protected] https://lists.openstreetmap.org/listinfo/historic
