Hi!
OpenStreetMap is a map that anyone can edit and anyone can freely reuse. It has a huge ecosystem, and can thus be a bit confusing to edit or to work with.
I thought that having a weekly thread to ask all beginner questions would be nice for everyone interested, so - go for it!
If you know the answer to a question, please answer (so that I don’t have to answer everything).
Believe it or not, I started last week. :)
My area has been doing sidewalks as separate ways, though very little is complete. I’ve already filled in more than a square kilometer of sidewalks with all their crossings and curbs, but just encountered my first intersection with this sort of weird grey area crossing where there is a traffic light but no pedestrian signal.
Well, that is impressive! Personally, I only map sidewalks separately if they are clearly separated by a decent amount (>1m) over a longer stretch of pavement
