[OSM-talk] copying numbering (ref)

[Mario Frasca]

Hi everybody

in Panama I've been looking for official sources of information about 
road numbering, and could only find out that the 'Panamericana' is road 
#1.  (road signs all over the place tell you this).  for the rest, I've 
interviewed an employee of the MOP (Ministerio Obras Públicas), who 
alleged that they don't really use numbers for roads except internally, 
and that in this case the road number starts with a leading digit 
identifying the province, luckily it's 9 provinces in Panama.

now a couple of concrete examples of data in our database.

road #33, in Veraguas.  that's province #9.

roads #12, 18, 47, 48, 110, all in Chiriquí, that's province #4 ('Ch' 
goes as one letter, so it follow Coclé and Colón).  (the ones with the 
leading 4 agree with my MOP source).

so far so good.  the curious part is that all these numbers are also in 
Google Maps, included the suspicious ones.

I've placed questions in the corresponding changesets, and I have 
received replies, but quite non factual.

road #28 (according to Google) is road #91 according to us.  it's 
Veraguas, so the leading 9 might be correct.  here it's curious that it 
was created as #28 also in OSM 
(https://www.openstreetmap.org/changeset/35351526) then changed to 91 
(https://www.openstreetmap.org/changeset/63256732).

what would you do?
