Hi Matthias,

As you are aware, your questions are not easy to answer. I hope others
will contribute more detailed answers.

My short answer would be that the collective "wiseness" about this is
likely emerging in the collective tools, like the OSM database itself,
the wiki page (
), and maybe this mailing list. Even looking at the wiki history is a
way to get a glance at this on-going discussion.

Probably, the best collective intelligence emerges when each contributor
tries his best, given his or her knowledge and skills, to contribute to it.

Thank you for doing it in on your own way (and underlining the need for
clearer guidelines).

Regarding imagery, from what I have heard, other images, with relatively
high resolution and likely more extended coverage "should" become
available "soon".

A petition that might make sense to me could to Google, to ask them to
allow OSM to trace from their imagery that they already make available
online, at least in major humanitarian crises, and like they temporarily
did for Haiti last year. But that's a big subject...

Best wishes,
