Rationale

Provide a classification scheme for hiking trails.

  • Especially for mountain trails, it is crucial to know wether a trail can be done in sneakers or wether you need ice axe and climbing irons.
  • Since Google Maps and the like are pretty unusable for hiking (because they denote only very few trails), this is a region where OSM can be of great value soon and for a long time.
  • Many mountaineers already utilize GPSs. It would be great to win as many of them as possible as contributers to OSM.

As far as I know, there is no internationally standardized classification schema. Thus, I propose to incorporate the classification of the Swiss Alpine Club (source in german). Not because I am from Switzerland (I am not), but because in my humble opinion this one is easy to understand and well defined. Scale of difficulty for hiking trails (english, french, italiano, german abstract).

The following table constitutes a 1:1 translation of the SAC scale. Please see the tables further below for the actual tagging proposal.

SAC Scale Trail Terrain Requirements
T1 "Hiking" Trail well cleared Area flat or slightly sloped, no fall hazard None, orientation unproblematic, no map required
T2 "Mountain Hiking" Trail with continuous line and balanced ascent Terrain partially steep, fall hazard possible
  • Hiking shoes recommended
  • Basic sense of direction
  • Some sure footedness
T3 "Demanding Mountain Hiking" Track mostly visible, exposed sites may be secured with ropes or chains, possible need to use hands for balance Partly exposed sites with fall hazard, scree, pathless jagged rocks
  • Well sure-footed
  • Good hiking shoes
  • Medium sense of direction
  • Basic alpine experience
T4 "Alpine Hiking" Path sometimes invisible, route partly pathless, sometimes need for hand use to get ahead Terrain quite exposed, precarious grassy acclivities, jagged rocks, facile snow-free glaciers
  • Familiarity with exposed terrain
  • Solid trekking boots
  • Some ability for terrain assessment and good orientation
  • Alpine experience
T5 "Demanding alpine hiking" Often pathless, single plainly climbing up to second grade Exposed, demanding terrain, jagged rocks, few dangerous glacier and névé
  • Mountaineering boots
  • Reliable assessment of terrain and very good orientation
  • Profound alpine experience
  • Elementary knowledge of handling with ice axe and rope
T6 "Difficult alpine hiking" Mostly pathless, climbing up to second grade Often very exposed, precarious jagged rocks, glacier with danger to slip and fall
  • Excellent orientation
  • Mature alpine experience
  • Familiarity with the handling of technical alpine equipment

Applies to

highway=path

AND

highway=footway

Usage, Tags and Values

Inspired by some comment on the discussion page, I decided to extract all properties that deal with trail visibility and orientation from the SAC scale and put them into a separate tag "trail_visibility". IMHO, both tags are clearly separated and totally independent from each other. There is no reason to mangle these properties together.

Tag SAC Scale Trail Terrain Requirements
sac_scale="hiking" T1 Trail well cleared Area flat or slightly sloped, no fall hazard None
sac_scale="mountain_hiking" T2 Trail with continuous line and balanced ascent Terrain partially steep, fall hazard possible
  • Hiking shoes recommended
  • Some sure footedness
sac_scale="demanding_mountain_hiking" T3 exposed sites may be secured with ropes or chains, possible need to use hands for balance Partly exposed sites with fall hazard, scree, pathless jagged rocks
  • Well sure-footed
  • Good hiking shoes
  • Basic alpine experience
sac_scale="alpine_hiking" T4 sometimes need for hand use to get ahead Terrain quite exposed, precarious grassy acclivities, jagged rocks, facile snow-free glaciers
  • Familiarity with exposed terrain
  • Solid trekking boots
  • Some ability for terrain assessment
  • Alpine experience
sac_scale="demanding_alpine_hiking" T5 single plainly climbing up to second grade Exposed, demanding terrain, jagged rocks, few dangerous glacier and névé
  • Mountaineering boots
  • Reliable assessment of terrain
  • Profound alpine experience
  • Elementary knowledge of handling with ice axe and rope
sac_scale="difficult_alpine_hiking" T6 climbing up to second grade Often very exposed, precarious jagged rocks, glacier with danger to slip and fall
  • Mature alpine experience
  • Familiarity with the handling of technical alpine equipment


Tag Trail Requirements
trail_visibility=excellent Unambiguous path or markers everywhere None, orientation unproblematic, no map required
trail_visibility=good Next marker always visible, but sometimes has to be searched for. Basic sense of direction, map recommended
trail_visibility=intermediate Track mostly visible Good sense of direction, map required
trail_visibility=bad Path sometimes invisible, route partly pathless Basic skills in orientation
trail_visibility=horrible Often pathless Advanced orientational skills
trail_visibility=no Mostly pathless Excellent orientational skills

Deprecates

nothing

Rendering

Generally, I think tag proposals do not necessarily need rendering definitions at all. First, there are many different renderers (Mapnik, Osmarender, Mkgmap) with different abilities in terms of colors and patterns. Second, this decision is independent of the tag schema. Comments on the discussion page agreed that categories above T3 should NOT be mapped similar to normal footways for the safety considerations.

Voting

If you oppose this proposal, please indicate wether you approve a version with a different key (see discussion page) or a version based on a 1:1 translation of the SAC scale (without separating the trail_visibility).

  • I approve this proposal I approve this proposal. I like the fact that the trail visability is a seperate key as this can be applied to other types of trails (such as cycling, ATV/Quad, snowshoe, etc.) --Mungewell 23:32, 2 June 2008 (UTC)

  • I approve this proposal I approve this proposal. because we realy need it, but am I the only one to think there are still too much levels ? Sletuffe 14:17, 3 June 2008 (UTC)
  • I approve this proposal I approve this proposal. Excellent idea. I live in Norway, so it is an appropriate classification scheme for my locality. There are certainly not too many levels - the locals here (like UK fellrunners) happily jog up and down T3 paths in training shoes. --alastairj 23:18, 3 June 2008 (UTC)
  • I oppose this proposal I oppose this proposal. Nothing wrong with the proposal, it's the process that's flawed see https://www.openstreetmap.org/user/bruce89/diary/1835 -- Nic 08:52, 7 June 2008 (UTC)
