Hiya, I see you're taking on the sidewalks in this area. I'm doing the same in Rosemont and thought I'd pass along some resources that I'm following in order to make the data we add the most useful possible for people who use mobility tools. [This video](https://www.youtube.com/watch?v=_AczR5YHPdw) explains a lot of the standards.

A few things I've noticed about your edits in this area:

- Are you using the offset of 0.6, -1.54 that is the standard for Bing imagery for the area? If not, you should write this down and start using it from now on so that your edits align with others'.
- Some of your crossings are labelled as Marked, but they appear in the satellite imagery to be unmarked. I know this changes a lot (paint doesn't last long through the winters here!) but we should try to use each tag when appropriate.
- It's helpful to add a Curb node to each endpoint of a crossing — though not in the middle of a sidewalk line, because that might imply to routing software that one has to traverse a curb when continuing on a sidewalk when one doesn't, if that makes sense. I don't add any further detail to the curbs in the iD editor, since it's hard to know their height, but instead scout this on location with Street Complete.
- My understanding of `concrete:plates` is that it is for premade plates that are moved into place, not for concrete poured on site.
- There are also some complicated standards for where sidewalks cross driveways, that I can elaborate on.  I've been writing up a document to try to help consolidate the data on how to do sidewalks to the best standard, but haven't finished it yet.

I would very much like to coordinate with you to continue work on the sidewalks in the greater Montreal area!  :)
