[Osmf-talk] [OSM-talk] Way to delete buildings added by specific user, or help reverting?

[joost schouppe]

Haven't looked at the data itself, but from the comments here, I'd say
convert them to nodes. Since in this case the mapper clearly didn't put
very much effort in it, I wouldn't mind if the history of the first object
is lost. I reckon later you want to identify "empty areas" to be able to
complete the map with a certain level of quality. That is still easy to
achieve if you disregard node-buildings or in fact the buildings returned
by the very query described above.

However do keep in mind that we always build upon the work of others. We
might start with a single building outline of a row of houses with bad
geometry because we had poor imagery. Then we split them up into individual
houses. Then we might improve their geometry with better imagery or open
data. And next, we might split them up into building parts to model the
different levels.

Don't be surprised if the mapper working on the next level is calling
-your- work crap if you throw around those kinds of words too lightly now.

Even if some of your community have very high quality thresholds, remember
that we always want to accomodate "the amateur". They might mess things up,
but they are the eyes on the ground we need. And we should aim to help them
grow, not scare them away. Maybe in this  case, it would be actually better
to scare that particular mapper away. But sometimes you'd be surprised, if
you give them a chance.

While I do understand an occasional flash of rage (we care about this
project, and it's hard to see it suffer), don't forget that your flash of
rage will be forever associated with the OSM data. Please try to avoid it.
And if it does happen, please apologize about it -  not necesarily to the
mapper, rather to anyone who sees it. In the long run, being a welcoming
community, even in the face of "bad mapping" is doing the project a better
service than making a map considered perfect by a few people who think they
know how it's done (even if they're probably right).

All the best,
Joost
