Hi Mark
I was wondering in the future if street names etc. could be derived from
Mapillary (attribution source=Mapillary) where images exist?
Cheers

So, a few months ago I stumbled upon a note
(https://www.openstreetmap.org/note/2158104#map=19/51.49829/-0.32762)
that StreetComplete left saying, that the street couldn't be given a
name because there's none shown.
Back then, I used streetmap.co.uk
(https://www.streetmap.co.uk/map.srf?X=516161&Y=179063&A=Y&Z=106) in
hopes to finding something - but only got "FAI RD." which - to me -
makes no sense.
Also, using https://os.openstreetmap.org/ makes it look like that's just
an access path to houses around it, which is (IMHO) not entirely true as
the way directly linking Southdown Av. and Boston Rd. clearly is
publicly accessible.
Now, using the above mentioned map
(https://osm.mathmos.net/addresses/uprn/#19/51.4983/-0.3279) I now know,
that this street has the UPRN ID 12145988.
That may not be the UPRN of the path or street. It may be the UPRN of
the open space that the path runs through. The path is more likely to
have a USRN (unique street reference number) than a UPRN.
To find the USRN of the path, you need to use the lookup tables
supplied by OS. Doing that, we find that the associated USRN is 20602512.
Now, there's no open data source which will directly tell you the name
of a USRN (at least, not until we start putting them into OSM). The
long way of doing so is to find the matching LineString in OS OpenMap
Local, and see what name it has there.
However, it can be done directly via a non-open source. If you go to
https://www.findmystreet.co.uk/map and zoom in on the location, then
click the street to bring up the USRN details, it will give the name
(and also confirm that the USRN from the OS lookup table is correct).
Or use the search box and search for USRN 20602512.
From an OSM point of view, that would normally be a dead end. Even if
you can view the information on a non-open source, you can't
incorporate it into OSM. However, in this case, we already have an
abbreviated name from an open source. So all we are learning from the
closed source is the full text of the abbreviation. Whether that makes
it acceptable to include the full name into OSM is a matter of debate.
I'll leave that decision up to others, but, for reference, the name of
the street is Fairfield Road.
Mark
