I’m on Street Complete and I’m trying to differentiate between Concrete, Concrete slabs, and concrete lanes. There’s a walkway that’s just a normal concrete walkway, I didn’t know there were so many designations for this.

      I have to say it only adds to my confusion. What the heck is a “concrete plate”??

      the example looks like the worst possible surface imaginable for a road.

        I was also confused. I’ve been using concrete:plates for almost all walkways that I’ve encountered. On surface=concrete:plates it says this:

        surface=concrete - concrete forming a large surface, typically cast in place and may have predetermined breaking joints

        Which is confusing, because sidewalks AFAIK are cast in place and have predetermined breaking joints, but it seems like surface=concrete is more for mostly continuous concrete surfaces regardless of that text?

          As I understand it, concrete plates, at least in the UK, tend to be quite big, like the road here:

          Concrete Road

          You might find though that pavements / sidewalks are made up of smaller plates, as they’re easier to transport and fit, rather than waiting for a large area of concrete to set. The only paths that I can think of right now that are concrete are on private property, so I can’t link to them. They’re things like garden paths and are continuous.

          If you’re not sure though, you can always tag as surface=concrete and let someone else add any extra detail in the future. At least then the basics are there :)

    There might be something on the wiki, in the meantime how I decide is:

    • if it’s a single expanse of poured concrete it’s Concrete
    • if there is dirt / grass between two parallel tracks of concrete (whether or not the tracks have any joins) it’s Concrete Lanes
    • if it’s just concrete but there are seams where it’s been poured separately, Concrete Slabs

    And if it’s anything else I skip.

      You’re only supposed to use slabs (plates) if they were pre-made. If it was poured (whether in one batch or multiple), the wiki says it should be just “concrete”.

      https://wiki.openstreetmap.org/wiki/Key:surface :

      concrete: Portland cement concrete, forming a large surface, typically cast in place and may have predetermined breaking joints. For pre-fabricated plates, please use concrete:plates or concrete:lanes if you know how the concrete is laid out and one of these tags fits.

      edit: Tbh most people probably don’t realize this, I probably mistagged some myself. I assume even advanced software would treat “concrete” and “concrete:plates” equally, perhaps giving some special treatment for “concrete:lanes”.
