[OSM-talk] wheelmap.org batch updates

[andy at onthewings.net]

Hi list,

I saw that wheelmap.org was discussed in the broad meeting last year ([2022-03](https://wiki.osmfoundation.org/wiki/Board/Minutes/2022-03#Contributions_without_individual_OSM_accounts)), but I still havequestions/suggestions regarding wheelmap.org's contribution to osm.

Currently wheelmap.org users are contributing anonymously. Wheelmap.org contributions are batched periodically before submitting to osm (I think). This often creates osm changesets that cover a very large area. It pollutes osm local area history, and it's hard to isolate bad edits.

My suggestion would be to use smaller batches. For example, each individual wheelmap.org usage session get batched separately. It would still allow users to stay anonymous, yet group related changes in a single changeset, assuming people work on a specific area in each wheelmap.org usage session.

Implementation-wise, a random id is generated when opening wheelmap.org, edits will be labeled with said id, and the wheelmap.org server batch edits using this id.

If my suggestion is good, it would be great if board/DWG can communicate this with wheelmap.org. I don't want to contact wheelmap.org directly since I don't think I can represent osm.

Cheers,
Andy
