[talk-au] Our work in last two weeks

[Martijn van Exel]

It sounds like one of those things where opinions are going to vary. Personally I would split them, but I don’t think it’s a big deal to do it one way or the other, and it doesn’t affect the map either way.

Mapping to make some random QA tool happy doesn’t sound tenable to me. Horea (my colleague) shared the OSMCha links mainly because that tool makes it easy to show all changesets of a group of mappers in one place. I think it’s a bit too opinionated when it comes to identifying ‘errors’. But hey, it’s open source software..:)

I’m happy that our work is being scrutinized. Please keep watching our work, we need your feedback to make sure we’re doing everything according to local best practices.

As an example, have a look at https://www.openstreetmap.org/relation/1284045 <https://www.openstreetmap.org/relation/1284045> - ways https://www.openstreetmap.org/way/175260353 <https://www.openstreetmap.org/way/175260353> and https://www.openstreetmap.org/way/175260354 <https://www.openstreetmap.org/way/175260354> are the respective forward members for each direction of travel. (Probably easier to see in the relation editor in JOSM)
