CAI - Club Alpino Italiano (Italian Alpine Club) path classification scale
Status: Draft (under way)
Proposed by: AlfredoSP
Tagging: cai_scale=T,E,EE,etc
Drafted on: 2016-06-03

Proposal

The idea is to introduce a tagging localization in Italy for path difficulty classification. Same meaning of sac_scale=* but based on the local alpine club classification (CAI - Club Alpino Italiano)

Rationale

Italian hikers are used to the italian classification.

Foreign hikers could find it useful since it's widely diffused on the Italian maps and corresponds to indication on the ground.

sac_scale mainly refers to mountain trails while in other places of the world (Italy is an example) there are a lot of trails in flat areas or hills areas that cannot be classified properly with it.

Trails classified with sac_scale=demanding_alpine_hiking or more, in Italy can be split in 2 categories:

  1. protected trails (so called "vie ferrate") that are protected with chains, ropes, bolts, etc
  2. alpine routes that have a different classification and very often are unmapped.

It's not meant to replace sac_scale nor to duplicate it, it's rather a proposal of integration and gaps filling limited to the Italian territory.

Ideally the mappers who are familiar with it should encode both and cai_scale tag should be added as much as possible from the official classification found on the signs.

Moreover it's a way to involve more actively the CAI itself to become a more active contributor to OSM.

Examples

Tag CAI Scale Description Requirements Gap Illustration
cai_scale=T T Touristic. Tipically these paths (often tracks) are flat with no dangers, might be thematic or storic and do not require particular efforts Hiking shoes, enough water, snacks, proper clothes Although this can be classified with sac_scale=hiking is in reality a step below therefore it represent a gap
Thumb
cai_scale=E E For hikers. These are typically paths (often with signs). Besides hiking shoes, proper clothes, etc it's required some orientering capabilities and enough training This can be classified with sac_scale=hiking therefore it represent the first step of sac_scale
Thumb
cai_scale=EE EE For expert hikers. Paths can be signed but may be on slippery grass, jagged rocks, some not difficult passages with snow Beside the standard adequate equipment mentined above, it's required training and knowledge of the alpine environment This covers sac_scale=mountain_hiking and sac_scale=demanding_mountain_hiking
Thumb
cai_scale=EAI EAI For expert hikers with mountain (snow) equipment. Paths can be partially protected with chains, ropes, bolts, etc. It's required harness, daisy chain, ropes, axes, crampons, etc This covers (or in between) sac_scale=demanding_mountain_hiking and sac_scale=alpine_hiking
cai_scale=EEA:F EEA:F Trail surely protected with chains, ropes, bolts, etc.
Difficulty:easy
Not very exposed and with long portions of hiking
It's required helmet, harness, daisy chain, ropes, etc These are all protected trails that may fall in a a range between sac_scale=demanding_alpine_hiking and sac_scale=difficult_alpine_hiking but in reality there is no easy relation
Thumb
cai_scale=EEA:PD EEA:PD Trail surely protected with chains, ropes, bolts, etc.
Difficulty:medium
Long and exposed but not very challenging
It's required helmet, harness, daisy chain, ropes, and a good training These are all protected trails that may fall in a a range between sac_scale=demanding_alpine_hiking and sac_scale=difficult_alpine_hiking but in reality there is no easy relation
cai_scale=EEA:D EEA:D Trail surely protected with chains, ropes, bolts, etc.
Difficulty:difficult
Athletic passages, some overhanging passages
It's required helmet, harness, daisy chain, ropes, good training, strength These are all protected trails that may fall in a a range between sac_scale=demanding_alpine_hiking and sac_scale=difficult_alpine_hiking but in reality there is no easy relation
cai_scale=EEA:MD EEA:MD Trail surely protected with chains, ropes, bolts, etc.
Difficulty:very difficult
Acrobatic passages, overhanging passages, challenging
It's required helmet, harness, daisy chain, ropes, excellent training, strength, resistance These are all protected trails that may fall in a a range between sac_scale=demanding_alpine_hiking and sac_scale=difficult_alpine_hiking but in reality there is no easy relation
cai_scale=EEA:E EEA:E Trail surely protected with chains, ropes, bolts, etc.
Difficulty:extremely difficult
Acrobatic passages, overhanging passages, challenging, some dangerous passages
It's required helmet, harness, daisy chain, ropes, excellent training, strength, resistance These are all protected trails that may fall in a a range between sac_scale=demanding_alpine_hiking and sac_scale=difficult_alpine_hiking but in reality there is no easy relation

Tagging

Applies to

After various discussions it appeared logical to apply this tag to the relation because it represents a judgement of the itinerary as a whole. Applying to the single ways is not forbidden but it should not be missing from the relation.

Rendering

The CAI has already some guidelines on how the paths should be rendered based on the difficulty that could be easily applied if the relations are tagged accordingly.
