invalid label (stale or from an external source)

[matkoniecz]

• What did you see?

label "Nowy Miasto" that appears to not be present in current OSM data

• I tried searching for it by Nominatim - http://www.openstreetmap.org/search?query=Nowy+Miasto,%20Krak%C3%B3w#map=18/50.06645/19.94610
• and overpass http://overpass-turbo.eu/s/swb
• again, even more inclusive overpass http://overpass-turbo.eu/s/swc

• What did you expect to see?

nothing

• What map location are you having problems with? City and country are helpful, as well as tile coordinates or latitude / longitude.
• Screenshot? Props for animated gifs.

There are two problems with it - "Nowe Miasto" (described at https://pl.wikipedia.org/wiki/Nowe_Miasto_w_Krakowie ) is name for (partially/mostly/almost completely failed) urban project, I am not aware of anybody using this name as an orientation point/area of city (though I may be wrong - but given that it is missing from OSM despite good coverage of names at least indicates that I am not an outlier).

And certainly "Nowy Miasto" is ungrammatical, if anything it should be "Nowe Miasto".

In general, place names in Poland are rather well mapped and language is tricky so I am unsure about use of third-party data.

Thanks for pointing that out!

You're right; that label doesn't come from OSM. We take neighbourhood (and macrohood, microhood) labels from Who's On First, and they should be given a property source: whosonfirst.mapzen.com to recognise this in the output GeoJSON, TopoJSON or MVT.

I've submitted an issue about this datum on the main tracker. So hopefully will be fixed soon!

I missed source field, thanks for pointing this out!

I added

, not: {source: [whosonfirst.mapzen.com]}

to nix this value and future wrong values. I also fixed duplicates that I wanted to investigate for some time.

@matkoniecz Can you tell us more about the duplicates, please? We have bandwidth to fix them if you provide some direction.

Hiding all source: [whosonfirst.mapzen.com] will hide most neighbourhood labels on the map – unless the ones in OSM are tagged something other than neighbourhood.

whosonfirst-data/whosonfirst-data#1022 - but I am unsure of

given what I see at https://github.com/whosonfirst-data/whosonfirst-data/pulls?page=2&q=is%3Apr+is%3Aopen

I will report more after issue that I just created is fixed and already produced PRs are processed.

Hiding all source: [whosonfirst.mapzen.com] will hide most neighbourhood labels on the map – unless the ones in OSM are tagged something other than neighbourhood.

So OSM labels for neighbourhoods are discarded to make space for data from whosonfirst? At least in Kraków in my experience whosonfirst labels are quite low quality and using OSM data would be better.

And clear duplicate reported at #1418

@matkoniecz FYI Who's On First PRs are back near "Inbox 0" levels.
