Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

I'm not quite there.
What I saw in Unpaved Track Pictures I would classify as Unmaintained Track Road with Smoothness Level https://wiki.openstreetmap.org/wiki/Key:smoothness of (specialized_off_road_wheels) tractor, ATV
The Unpaved Unclassified I would classify as Unmaintained Track Road with Smoothness Level (robust_wheels) trekking bike, normal cars.  The reason for this is that they are very narrow and the trees will leave marks in the paint job and they are not smooth enough for low riding cars as well. So anyone with a nice car will not risk the damage.  You can clearly see these are narrow one lane and the tire tracks some with grass in the middle are clearly visible.
The Unpaved Tertiary pictures I would classify as Unclassified Roads bumping them up where appropriate. For example https://www.openstreetmap.org/#map=15/49.0947/-54.8278 I have reduced to a Tertiary Road the Salmon Pond Forest Resource Road. I kept this above Unclassified because you could technically argue that it connects The Towns of Glenwood, Birchy Bay and Clarkes Head.  Although no one will actually use these woods roads for that purpose as there are perfectly good well maintained paved highways connecting these communities.
This sums up our dispute as GnasherNF bumps all forest resource roads up above unclassified, and had huge numbers of these roads https://www.openstreetmap.org/#map=15/49.1429/-55.6524 up as Secondary and Primary.
I'll only give a tertiary rating to a woods road that would link small communities and I'm not fond of that when there are paved highways linking these communities.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

When I started mapping, there were not many unpaved roads mapped in Newfoundland. Most roads that were mapped were tagged as secondary and tertiary roads, so I used them as the example to follow and made most of my roads either secondary or tertiary. The last link listed above is an excellent example as those roads were added in 2012 (not by me) as all secondary. I have actually been downgrading these roads, NOT upgrading them as stated. Feel free to examine the history of these ways to verify.

I only realized there was an issue with tagging these roads as secondary/tertiary when I noticed all the roads I was adding were being changed to highway=track with no tracktype applied. I am willing to admit my mistakes and change the way I tag. I already have, and will continue to remain open to change as it comes up.

Let me clearly state - I want these road networks to be accurate. That is why I add them. I do not want them to be inaccurate.

Traffic patterns on the unpaved roads in Newfoundland are similar to roads in a city. In a city, residential roads lead to tertiary roads, which lead to secondary roads, which lead to primary roads, and then to trunk roads, each carrying more traffic. In the rural areas, tracks lead to roads, which sometimes lead to tertiary roads which cover or link larger areas, which then lead to the paved road network. If you are navigating the woods (why else use a map?), a tertiary road will get you out, and are generally wider and better maintained.

Here are some examples of unpaved roads I tag as tertiary:
1. https://www.openstreetmap.org/way/146628702 - starts here and continues west, only broken by bridges. Over 60km long and links paved highways, and connects all of the roads and buildings in between to the paved network.
2. https://www.openstreetmap.org/way/146236518 - starts here and continues east. Over 90 km long and only broken by bridges. Again, links all roads and tracks and buildings in between to the paved road network on both ends.
3. https://www.openstreetmap.org/way/146220394 - stretches east and west along the south side of Red Indian Lake. Over 70km long and links to the paved road network and the nearest town of Millertown to the east. There are a lot of side roads along this route and it is very easy to get lost in unmapped, dead-end roads.
4. https://www.openstreetmap.org/way/146307435 - connects the TCH in the south to the paved Botwood highway in the east. All other roads and tracks and buildings in this area connect to the paved network through these tertiary roads.

It is important that these unpaved roads are tagged as unpaved. If a mapper has worries about people accidentally getting routed onto these roads (which OSM isn't responsible for) then note that routing software gives priority to paved networks and most times will only route onto unpaved roads if paved roads are not available.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

Like hadw said, it's hard to determine whether tertiary is appropriate for the first batch without knowing if they're used by locals for driving between towns or not. I suspect that they probably aren't, in which case unclassified would be more appropriate.

As for the ones you consider unclassified, those appear to me to be clearly tracks with one of the higher track_type values (grade1 to 3). The ones you consider tracks can be left as such, but should be given the lower track_type values (grade3 to 5).

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

The 4 examples really don't meet the Tertiary definition.  To move from unclassified to Tertiary "A road linking small settlements, or the local centres of a large town or city." 
While I think Unclassified may be better I usually won't bother to change a road 1 level unless something really is out of sorts.  It is why I do pay more attention to the difference between Unmaintained Track Road (not suitable for all cars and vehicles,,,,) and unclassified (which is the level most any vehicle can drive without worry about damaging a vehicle.

Paved or unpaved really does not matter moving beyond unclassified although most higher level roads are paved that should not be a primary factor in making the decision.

Getting out of the woods is not a factor in determining if a road is a Tertiary Road, an unclassified road is a good quality road that will get you in or out.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

I understand it can be frustrating when trying to communicate ideas to others across the internet. I apologize to the other readers of this thread, but when I try to contact the original poster directly, he keeps referring back to this thread instead, so I will address the issues here.

I agree with this point of view, and yet you change all unclassified roads I tag to track, including ones that are maintained year round and including ones I drive on with a Prius with barely any ground clearance.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

I have and will continue to ignore who made a previous edit when I look at or edit anything.
I map in grids or sections at a time.
I refer you back to the forums to see how others look at the issues and keep this conversation in one place.
You revert back to personal attacks when talk about the edits do not go your way.
As previously stated when you get more people agreeing in this forum with you, I will change, as long as people are agreeing along the same lines as the way I edit then I will not change.
I refer you back to a full page from the wiki not just the lines I like with the hopes you read the whole page and try and get the full picture not just the parts of a sentence you like.
Moving forward I will only reply to others in this forum and will now ignore you completely.
Goodbye.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

Just referring to references that I am following him around specifically or intentionally, tossing a phrase like vandalism when talking about my edits.  Or quoting parts of my sentences try to rephrase or twist what I am saying or talking about having tagging wars.

The topic is when does a Track Road become unclassified and when does a road become Tertiary. GnasherNF is creating towns and city streets in the forest where there are only unmaintained woods roads.  Yes the logging companies keep them up for 5 years or so at a time then they are abandoned for 20 or 30 or whatever length it takes for the new trees to reach a harvest height. No city or govenment looks after them therefore they are unmaintained track roads.

The pictures that GnasherNF posted as Tertiary are the only ones that should be unclassified from my view.

From the pictures and the links to the areas in question I'd like to see what way others a leaning.

There is not much point in myself and GnasherNF continuing to debate this because we clearly have different views and are not going to convince ourselves that the other person is right.  I just edited the last couple of sentences because my previous wording seemed like I wanted the thread to be ended but I'd still like to hear from others.

I'm not sure what benefit there would be to continuing this discussion when the two primary contributors aren't interested in having a good-faith discussion of the issues. GnasherNF doesn't seem to be interested in addressing any of the points raised by any of the other contributors in this discussion and will seemingly continue to map as they always have. You - knowing full-well that a discussion of the matter is underway - continue to change highway classifications and give flimsy excuses like "well, I didn't look at who made the edit," rather than hold off on making any such changes until the discussion ran its course. Face it, you knew that there was a good chance that you were changing GnasherNF's contributions and chose to inflame the situation anyway.

If you both decide that you're ready and willing to actually discuss this issue, then maybe we can have a healthy discussion about highway tagging guidelines in Canada. Otherwise, I'll just sit back here on the opposite side of the country and rest easy knowing that I won't have to deal with the mess that is the OSM road network in Newfoundland.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

I do agree with you, both of us are too stubborn.  Which again is why I started this thread.  The concept was to see what way the community is leaning.

Unfortunately it looks like the few that posted are also split.

I never said or never meant that I did not know I would be changing edits made by GnasherNF, I meant that I am not going to sit down review the history of every edit to avoid his.  Both of us do thousands of edits, I can't begin to count how many times some one has changed an edit I made and since I was actually mapping in this area several years before GnasherNF I'd be will to bet that there are plenty of the roads that he is complaining about that were originally edited by me, but again I haven't looked for that either.

As for mess?  Roads are being mapped and improved. The primary and secondary highways are be taken out of the woods.  So there is only the distinction of when to use Tertiary, and when to use track or unclassified.  So the maps are improving, we just are not in agreement on a few types.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

(Been away for a while; missed a lot of discussion for a topic that's important to me...)

This matches my understanding perfectly.  An understanding gleaned from studying the wiki at various levels, studying common practice, and simply what seems to make sense to me.

As I think I'd mentioned, tertiary is for roads more "significant" than run-of-the-mill unclassifieds; suitable for going longer distances, and/or to multiple destinations.  In another post, I think GnasherNF gave examples essentially backing this up.  Note that in many areas, there are no "settlements", thus no roads needed to connect them, but that doesn't mean there are no tertiary-suitable roads.  There may be gas plants, pulp mills, significant bridges, etc.  A road crossing a rarely-bridged river easily qualifies as tertiary to me.  A road with a nice curve instead of a corner, built for more traffic, again likely tertiary.  It's a judgement call.

Trying to push toward closure...  I'd wholeheartedly support updating the wikis with these images as examples.  How do we make decisions here?  Here's my vote.

I concur that the first batch might be unclassified or tertiary but you can't tell from the photo alone: If the road carries through traffic then probably tertiary but otherwise probably unclassified. Just because it is wide enough for two lanes of traffic and is maintained does not mean that it can't be unclassified.

The photos in the group labeled unclassified I'd mark as track as they look to be only wide enough for a single vehicle. I might tag them as service if they are short and are obviously used to access a building, etc. But I am tagging things that look like that as track in my area.

Some of the photos grouped under "unpaved track" look too narrow for even an ATV, I might consider tagging those as a path rather than a track.

As for 1 or 2 lane all bridges on all the roads in these pictures are 1 lane.  The logging companies don't spend the resources making them 2 lane.

I don't see why a "through road" can't be one lane at times.  I can think of some examples in my area.  A long road providing access to many unclassified roads, yet with one-lane bridges.  It's a more significant road than the ones that branch off from it, hence tertiary.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

Here is a current example, trying to make use of most of the tagging suggestions made so far. Zoom in and take a look around. https://www.openstreetmap.org/way/14623 … 4/-55.9194

Tertiary: An unclassified road carrying through traffic.
Unclassified: An unpaved road that can carry regular automobile traffic (usually 2 lanes but sometimes 1 with shoulder).
Track, tracktype=grade1: Not applicable, as paved tracks are not found in these areas.
Track, tracktype=grade2: Prepared roadbed. Can carry most automobile traffic without major issues. May shows sign of vegetation.
Track, tracktype=grade3: Prepared roadbed, mainly dry and hard, but overgrown or in the process of. Can carry automobile traffic.
Track, tracktype=grade4: Prepared roadbed, mainly soft or wet. Can carry automobile traffic but not recommended.
Track, tracktype=grade5: Roadbed same as surrounding terrain. Does not support automobile traffic, but can support ATVs.
Service: Roads leading to quarries or small groups of buildings (usually 1 lane with no shoulder).

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

That all looks fine, your Tertiary definition should be what is on the Wiki https://wiki.openstreetmap.org/wiki/Tag … y=tertiary
Bumping Forest Resource roads up to Tertiary should be limited as they seldom can be interpreted as meeting the definition.

Here is a current example, trying to make use of most of the tagging suggestions made so far. Zoom in and take a look around. https://www.openstreetmap.org/way/14623 … 4/-55.9194

Tertiary: An unclassified road carrying through traffic.
Unclassified: An unpaved road that can carry regular automobile traffic (usually 2 lanes but sometimes 1 with shoulder).
Track, tracktype=grade1: Not applicable, as paved tracks are not found in these areas.
Track, tracktype=grade2: Prepared roadbed. Can carry most automobile traffic without major issues. May shows sign of vegetation.
Track, tracktype=grade3: Prepared roadbed, mainly dry and hard, but overgrown or in the process of. Can carry automobile traffic.
Track, tracktype=grade4: Prepared roadbed, mainly soft or wet. Can carry automobile traffic but not recommended.

Re: When to use track roads or tertiary roads etc. Newfoundland, Canada

GnasherNF, I think your latest post and the example map looks pretty good. I'm not Canadian, but I grew up in the Northwest of the USA in an area with lots of forestry roads, and so I've become familiar with the different uses of track/unclassified/etc.
I'd probably keep most of those "tertiary" roads as "unclassified", unless they have significant traffic due to settlements or other destinations, or if they have a number of highway=unclassified branching off of them. You mentioned a 60km long road; that might be a good example. I would think that a Tertiary road in Canada should be maintained annually by the local governement, or the local private forestry company or private land owners should officially maintain it. Perhaps this could be discussed with other Canadian mappers to find out if there is a more official way to determine when a road can qualify as Tertiary?

I would not think that winter snow clearance is a necessary characteristic of "maintenance". In Portland, Oregon, even secondary highway will be unplowed during the rare snowstorms, and tertiary highways in Oregon and Washington are often impassable due to snow during the winter. Fortunately there are tags for seasonal closures, so an unclassified or tertiary road may be the correct tagging, even if it is only open during the summer, if the road sees significant public traffic during that season.

As far as highway=unclassified vs highway=track, I think it should be remembered that the highway classification system on OSM is primarily about road usage, not the quality of the road surface. So a badly-maintained road that is the only access for a set of residences or businesses should be highway=service if it is privately owned, even if it is surface=dirt, smoothness=very_bad and tracktype=grade3, and 3 meters wide. Clearly the residents and guests will need to use 4WD vehicles or ATVs of some kind for access.

But a gravel road with a relatively smooth surface and good drainage may be a track, if it is only used for logging/forestry vehicles or agricultural vehicles, and does not access residences, businesses or tourism destinations and is not maintained for the public.

I do think that in a developed country like Canada, a highway=unclassified should be passable by most passenger motor vehicles, however. Perhaps not sports cars or subcompacts with very low clearance, but regular cars should be able to get though, even if only at 10 km/h. And I would expect signs of maintenance: the road should not be 2 tracks or rutted out or have lots of vegetation growing between the wheel tracks, but should be regraded and maintained occasionally, since it is meant for public access. While minor roads in developing countries can be expected to be passable for 4WD/high clearance vehicles only, I would not expect this in North America.

I agree with your comments, except this part (quoted), but it boils down to how strictly we interpret the wiki.  I've seen some major forest roads, wide and in exceptional condition built for heavy traffic, that would qualify as "track" by the criteria above, because they're maintained for industry, not the public.  (Public are tolerated as indirect landowners; common signage about "private road" refers to industrial users who are expected to contribute to upkeep.)

In my mind, if you can see two parallel tire tracks/ruts/grooves, it's a "track".  If it's smooth, even roughly smooth (but it sees a grader occasionally) - that wouldn't be a track.  But the wiki doesn't make this distinction.  Maybe it should?
