Hello! I've just started using StreetComplete, and I want to make sure I understand the answers before I go through and make a bunch of garbage data.

In this picture, is the kerb a ramp, or flush?

The sidewalk deflects downwards, but it's not a ramp ramp like the example picture.

How about this one?

The kerb itself dips, but the sidewalk on this one looks more flat and does simply run into the road. And then it has the texture, obviously. Is this one different from the last one?

Also, just to check, I marked both of these sidewalks as "concrete". That's correct, right? I wondered about "concrete plate", because they're segmented, but the picture made concrete plate look much more substantial.

My other question was based on the "lit" tag for a bus stop. This bus stop has a street light near it, but there's no light on the bus stop itself. It sounds like that means it is lit? Would a non-lit stop just be one that is fully dark at night, then, with no kind of lighting anywhere near it at all?

This one is further from the street light, but still has line of sight. Lit?

Thanks very much for any help you have!

Only use flush if the transition would not be apparent to a blind person. Less than 3cm of curb. If a cane would catch the curb, it should be tagged as lowered.

StreetComplete's "curb ramp" option gives the curb the lowered tag, making it the same as if you picked the "a bit higher than road surface" option.

@psycotica0 concrete:plates are pre-formed chunks that can be moved into place. concrete is poured in-place, and is the correct value for sidewalks. I have never seen any actual concrete:plates in use in real life, but SC users are tagging it all the time. They should honestly make the difference more clear in the app.

As for lit tags, I turned those off because I didn't want to overthink it.

Yeah, I think the image for concrete plates in the app is from the wiki, and is kinda unclear because it's some rectangles of concrete. And I'm looking down and what I'm seeing is a series of rectangles made of concrete. I agree, though, with that in mind I feel like the app could benefit from some guidance there to say "concrete, perhaps with joints, such as for sidewalks" or "concrete plates, precast elsewhere and installed. Rarely used" or something. Just a bit of a nudge in the right direction.

I think the key feature of the picture on the wiki is that they have visible lift points near the corners.

In some of the pictures they have been filled, but in others they haven't.
