[Talk-ko] Highway labeling

[Robert Helvie]

Hi folks,

My understanding is that for most places (usually a country) on OSM there
are generally two ways to tag things- either by its physical nature or by
its use. Usually one or the other is adopted just out of initiative. I think
for the most part Korea is of the second nature, tagged by use.

Just to add my take on things ...

1. Motorway- all the expressways (ie. toll roads)

2. Trunk- If there is a need for this in Korea, I would put large multi-lane
main highways here. Highways that serve the same purpose as toll roads,
regional travel.

3. Primary- For the most part, I tag the largest, widest, most traveled
roads through a city as primary. After all they are the primary roads of the
city. If you want to put a description on it I would say divided or
non--divided with at least 3 lanes in each direction. But then again a road
with two lanes in each direction I 'might' tag as pimary if the city is
small or if the traffic is usually heavy on it. I would also suggest that
perhaps the trunk roads could be primary if they may not be that large. (I
generally don't map trunk or motorway roads unless I am correcting existing
data. I collect data by bike. I do occasionally ride the larger non-toll
roads though, and this is one of the reasons I might suggest they could be
primary, though I can see the argument for trunk. [Waffles anyone?])

4. Secondary- roads with two lanes each direction. Or roads with more lanes
each direction that as of yet do not have significant traffic (ie. when city
planners have the foresight to create wider roads though they don't actually
have the need for them yet. These could later be changed to primary in
time.)

5. Tertiary- I agree with Andrew on this one. If it has a yellow center
line, it is probably important enough to be at least a tertiary road.

6. Residential- Again I am in agreement. Though I would suggest that roads
within larger apartment complexes should be labeled 'service' rather than
residential. And roads that obviously go through an apartment complex could
be a residential or tertiary based on the use doctrine.

7 & 8 is where I respectfully disagree with Andrew, mostly because this is a
lot of what I like to ride. The other roads just get me out of the city.
;-)

I do not use unclassified.

If a blacktop (asphalt) roads leads off a tertiary eventually leading to
some houses or even 1 house, I tag it as residential. The asphalt roads,
even small ones, will usually have at least one white line along one side
(usually both sides), and this is my clue that it was laid down by the
city/provincial government, for the houses, thus residential.

If a road, off a residential or tertiary, just leads off out into the fields
or up into the mountains I tag it as a "Track | Grade1" either paved or
concrete (usually the latter). If it fits and I remember to do it, I add an
agricultural designation. If the road is unpaved it is a "Track | Grade2"
gravel or ground. I would also tag ridable mountain walking trails with
track if it is wide enough. Other wise it is path or hiking with bicycle:yes
tag. If it is a really crappy track which makes me want to get off the bike
and walk, I might tag it a Grade3. The muddy riverside road would be a track
for me too.

For service and footway I am in agreement with Andrew.

Again, I think for the most part, Korean roads are tagged by use. A lot of
the initial roads and tagging were most likely done by westerners, but I
think we should remember that our model, UK, USA, EU does
not necessarily fit well with the Korean system. Also, if you look at the
different maps available, Naver, Daum, Google KR, Yahoo KR, Paran, and
print, even they don't agree on what is primary, secondary,circle, or
square.

Adding my 2 cents to the total.
Jama rek,

Robert
