I'm editing a residential area in the US that has many sidewalks (tagged as My question is what to do if I don't have a pair of curb cuts, but simply access to the road itself (near parking). Tagging the way as A related question is what to do when I have multiple curb cuts near each other. Crossings between each of them doesn't make sense to me, since it's a residential road people can cross between any of them, including diagonally. Should I just connect to a common node on the road? |

This question is not easy to answer since mapping sidewalks, sloped curbs and crossings are called "micro-mapping" and are not extensively surveyed in OSM at the moment. So you are free to innovate or try to contact other people interested by the same level of details by other means like IRC or the OSM mailing lists (see Contact on the wiki) because at the moment, we don't have well established practices about these detailed things. Thanks for the great response. I'm glad you caught my error about tagging of the way as a crossing rather than just the node. For my question, I think I'd say the way should be tagged as highway=footway, with no special tag for the node where it intersects with the road.

Here's what I do now. I tag such "links" with For the second part, if there are dropped kerbs (aka curb cuts) on four corners of an intersection, I essentially draw a box connecting them, so I ignore the possibility of diagonal crossings, as that's typically not allowed or at least it's unusual to do so. Of course there are some cities which have such diagonal crossings, and those should be marked as such in that case. See this image on the wiki for how I would map this type of situation (though for three kerbs rather than four). |

It does not really answer the question but at that level of detail it seem to be appropriate to tag the footway/streeet areas in some way (landuse=street has been suggested) 1
The links are necessary for routing, while

Yes, they would be useful for rendering, or analysis. Also they can give you the information where the sidewalk ends and street starts. They give you the information about actual shape of the street (eg. oversized load can go over a sidewalk, but not through a house). You can find more uses. I am only saying that when you survey the area this deep, you can draw it to the map...

As noted in the selected answer, I shouldn't have tagged the way with
highway=crossing.For any reading along; apparently, only nodes should be tagged with highway=crossing. For micro-mappers, you'd want highway=footway + footway=crossing.
@Joel D Reid You don't need to comment on ancient questions to make a point. Moreover, to update, in recent months over the past year there were discussions about
virtual=yes, andfootway=link.I want to tag things correctly. Is the wiki the canonical source for recommended tagging practices? You mentioned tag:virtual, which I cannot find as a proposal nor guideline in the wiki.
@Kovoschiz Please don't assume my intent—I didn't comment to make a point. This question page was the first result in my searching, for example, despite being "ancient". This page is not archived or deleted, so I think it is here to inform people. So, my intent was: if I can help the next reader to jump to the answer, great.
