[talk-ph] changes of road types

Fri Jan 22 12:22:19 GMT 2010

Maybe we should describe unclassified roads in the Philippine context as roads within verified and/or urban areas that are of mixed use (commercial, retail, industrial, residential, farmland), while the residential roads can be described as a "road in either urban or rural areas that are within areas that are classified as mostly residential". The road tag can be used for roads that have no actual road types, as proposed/planned.

Tony Montana: Me, I want what's coming to me.
Manny Ribera: Oh, well what's coming to you?
Tony Montana: The world, chico, and everything in it.

Hi,

With the advent of more sat images outside Metro Manila I would like
to re-visit this discussion regarding road classes in rural areas.
As Eugene discussed below, rural roads are different.  I think we
should use the track and tracktype tags for most rural roads.

http://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrack
http://wiki.openstreetmap.org/wiki/Key:tracktype

As for highway=unclassified, I don't see this of much use in the
Philippines.  Unclassified is a legal UK road type and not some road
we don't know the proper class.

Unclassified
"No administrative classification. Unclassified roads typically form
the lowest form of the interconnecting grid network.
Note: This is not a marker for roads where we still need to choose a
highway tag (see highway=road for roads that require classification).
"

For people tracing from sat images but are unsure of the actual road
type please use highway=road

For comments.

cheers,
maning
