“whether a road is within a built-up area or not”

That’s the major issue around here (CZ): “source:maxspeed” alleviates this somewhat, but that’s even less frequent than maxspeed itself. OTOH, when this is determined, using the defaults is useful - maxspeed with source:maxspeed=sign/zone shows local variations.

“This has even been a relevant consideration for the otherwise ordinary residences of very famous people.” - are you referring to the Streisand effect? ( https://en.wikipedia.org/wiki/Streisand_effect - TL;DR: attempts to censor one photo of an otherwise uninteresting house, out of many such photos, did have an exactly opposite effect)

@alexkemp: Actually, it doesn’t even need accurate time to begin with - that’s just a helper for obtaining a GPS fix faster. Without, the fix is still usable, but a) more satellites are needed and/or b) time to fix is increased. Old GPS receivers had no RTC clock, the GPS fix has 4 coordinates (X,Y,Z,time).

Yup, that’s exactly what Humanitarian OpenStreetMap Team does: https://www.hotosm.org/

Perhaps the houses can be tagged with osm.wiki/Key:building:min_level and …level?

There’s “Labels and filters” - https://github.com/MichaelVL/osm-analytic-tracker

I do agree that it’s not entirely user-friendly to set up, and if you only ever need one simple filter, setting it up would be a hassle. Anything more, and in my experience the overhead of tuning a custom script becomes significant.

Interesting - why not OSMAT? osm.org/user/Cascafico/diary/42317

I would say that you’re reaching the limits of iD, the in-browser editor. Mind you, the editor is great (also thanks to recent improvements), but is better suited for smaller edits (zooming in could help?). Try JOSM: it has feature filtering, amongst other things (and can cope with a large number of objects more efficiently than going through the extra abstractions inherent in a webpage). Requires Java though, and has a steeper learning curve.

Interesting and useful - but you want to revoke your token ASAP. Pixellated block of ~8 letters of the [a-f0-9] set is just as good as posting it in plaintext: http://dheera.net/projects/blur

Yup. And reverted in short order - constant vigilance and whatnot. https://blog.openstreetmap.org/2018/08/30/osm-condemns-vandalism/
