Thank you. Great tool! It makes an inconsistency visible to people to
make a final decision.
It is probably like in chess. It is not a man alone, neither a
supercomputer, but a team of strong human players with usual computers
who win no-holds-barred championship.

As I see there is a tool for detect distance differences :
*OpenStreetMap - Wikidata Validator*
Each circle is an OpenStreetMap feature with a Wikidata tag.
Circle size and color are based on the distance in kilometers
between OpenStreetMap feature and Wikidata coordinates.
Large red circles mean the distance is greater than 10 kilometers,
which indicates a higher error rate.

Certainly a tool to check and correct obviously broken or
duplicate wikipedia=*, wikimedia_commons=*, wikidata=* links from
the OSM map would be very useful.
However, I've met inconsistencies which could be noticed only by a
knowledgeable human on the ground. For example, this coordinates
correction
<https://fr.wikipedia.org/w/index.php?title=Chapelle_Notre-Dame-des-Voirons_de_Bo%C3%ABge&diff=121789421&oldid=121556970>
for the chapel Chapelle Notre-Dame-des-Voirons de Boëge
<https://fr.wikipedia.org/wiki/Chapelle_Notre-Dame-des-Voirons_de_Bo%C3%ABge>
. Before this correction it had wrong coordinates placing it
erroneously on absolutely another mountain. I could correct it
reliably only after actually visiting this chapel for making some
photos for its article.
The comprehensive solution would be to have a dedicated Wikipedia
layer on the OpenStreetMap. Now we have Standard, Cycle,
Transport, and Humanitarian layers. Why not Wikipedia layer
similar to this
<http://ausleuchtung.ch/geo_wiki/?lat=46.18824490036672&lng=6.177406311035156&zm=14&lang=en&ds=wiki&rd=10>
, so that a user can select Wikipedia language and see the
geo-markers corresponding to Wikipedia articles on the map. Or see
clickable geo-markers corresponding to wikipedia=*,
wikimedia_commons=*, wikidata=* tags.
This tool is using MediaWIki API and Overpass API, but for the OSM
Wikipedia layer the data could be pre-calculated and synchronized
periodically in order not to overload the APIs.
In fact, I am using the OSM map mostly with Wikipedia markers. For
example, I was recently on a short holiday trip to Stockholm and
the first thing I do I look what Wikipedia articles exist for the
city
<http://ausleuchtung.ch/geo_wiki/?lat=59.324472209890146&lng=18.0710506439209&zm=16&lang=en&ds=wiki&rd=10>
to select places to visit and to read about. So in my opinion,
such a Wikipedia layer would be kind of synergy, - the creation of
a whole that is greater than the simple sum of its parts.
Best regards,
Oleksiy

Hi Yurik,
Nice work.
I'm interested in make such validation a service, to identify and
fix any inconsistencies between OpenStreetMap and
Wikipedia/Wikidata.
I'll be working on that on the next days.
Regards,
J. Gustavo

I have been steadily cleaning up some (many) broken Wikipedia and
Wikidata tags, and would like to solicit some help :)
To my knowledge, there is no site where one could add a set of
OSM IDs
that need attention (something like a bug tracker lite, where
one could
come and randomly pick a few IDs to fix), so I made a few tables:
List of Wikipedia tags that do not resolve to Wikidata tags.
Most of the
time, the WP tag is incorrect, sometimes it was deleted, and
very rarely
there is no matching Wikidata item (needs to be created by hand).
