RFE: Allow users to contribute under their own OSM account

[Lee-Carre]

Is your feature request related to a problem? Please describe.

Inspired by

• Changeset bounding box area #327
• other thematic-rendering websites

Describe the solution you'd like

Much like many other thematic renderings, being able to login using one's own OSM account (via Oauth, rather than requiring password), in order that submitted (wheelchair:*) changes be made via that user's account, instead of wheelmap_visitor.

Describe alternatives you've considered

• regular editors (StreetComplete, Vespucci) authenticated with one's own account. However, this significantly increases the barrier-to-entry for those interested in accessibility but not (necessarily) mapping (for its own sake).

Additional context

Besides attribution for contributions, this would enable enthusiasts to keep track of all their changes, regardless of where or how they're made, since all their changes would be logged in the history of their own account.

this significantly increases the barrier-to-entry

Only if it is made mandatory. This is not essential for ticket 327 (limit changeset bounding box) so it doesn't have to be, from my perspective.

Thanks for raising this issue! I can’t promise when / if we implement this, but if, it would be optional. I‘d love to have this feature again as it would encourage power users to map accessibility. I hope in the meantime it’s possible to implement it with better UX than the last existing version of it :)

Status update: This feature is definitely going to be part of a new version. It might start behind a feature flag (e.g. a URL parameter) at first, but will make it into Wheelmap again. We're going to experiment with this in the https://github.com/sozialhelden/wheelmap-frontend/tree/feature/osm-sync branch.
