Re: [talk-au] When is a Road a Track

[David Bannon]

Do you mean without seeing them yourself Warren ?  I personally think 
that you should only correct another mapper's work if you have 
personally seen something that needs correction. I am sure there are 
some exceptions. But here, in particular, you seem to have "negative" 
information.


Its also worth remembering that highway= indicates the purpose of the 
road or track, a number of other tags indicate its condition. In theory

Do I leave them alone or change the classification to highway:track?

I don't think it should be a hard rule that you must follow what the Main
Roads data says (if someone wanted authoritive data they would use it
directly) because they can be exceptions to this where on the ground
doesn't match up with that particular dataset.

That said, determining if it should be highway=unclassified or
highway=track isn't easy. I think it's more important to have other tags
like surface, track_type, etc than the correct highway tag (you can use
track_type on highway=unclassified).

I agree Eon4wd, my interest in OSM originated from my interest in 
bushwalking.  Often we can make an educated guess of tracktype from an 
aerial image and knowledge of the general area.  I suggest that if it is 
not clear you leave out the tracktype field, this implies unknown.


My point was really:

Do we accept the Main Roads Western Australia data as a list of 
officially recognised Roads ( highway = primary, residential, etc not = 
track or = path)?


I accept the point that highway = unclassified could be appropriate for 
a road that does not appear on the data base.

Re: [talk-au] When is a Road a Track

[Warin]

Does the Main roads Department show residential roads?
If not then I would also assume that the unclassified roads would not 
necessarily be displayed either.


On their website .. 
https://www.mainroads.wa.gov.au/OurRoads/Facts/Pages/StateRoadNetworkMaps.aspx


they say
"In the future, this may also be extended to include Department of 
Environment and Conservation roads."

"
Public roads not part of the State Road Network are generally local 
roads managed by Local Government or minor roads managed by other State 
Government agencies, such as national park roads managed by the 
Department of Environment and Conservation.  "


So I would not be confident that they show all the roads.

If you want to get more information on the individual roads then you 
should try contacting the original mapper.
