Hi!

We have taken a few days of discussion with key *«Obstacle»* (it derives
from «Difficult_Passability»... I have tried to answer all questions and I
have been added the proposals. I apologize if in any case it has not been:

http://wiki.openstreetmap.org/wiki/Proposed_features/Obstacle

Do you think that something isn't right or need more revisions? There are
some inconsistencies? More suggestions or doubts?
I think that the page needs to be cleaned, but all seems me important...
Any suggestions?

Thanks a lot! (and thanks for the comments received)

ALBERT

>    - obstacle=hole
>          - obstacle:bicycle=heap
>          - hazard_prone=yes
>          - hazard_type=landslide
>          - (optionally) obstacle_description: Landslide with heaps and
>          holes, and more landslides risk.
>       2. Other option (not the best) would be use two nodes (In this
>    example, I use the generic «obstacle», that represents impediment for
>    pedestrians). The nodes must be over the highway, therefore one will be
>    first and the other last:
>       - 1st NODE with tags:
>          - obstacle=hole
>       - 2n NODE with tags:
>          - obstacle=heap
>       - Chunk of way affected:
>          - hazard_prone=yes
>          - hazard_type=landslide
>       3. Other option (the bad, for me) could be:
>       - NODE or WAY with tags:
>          - obstacle=yes
>          - obstacle_description= Landslide with heaps and holes, and more
>          landslides risk.
>          - hazard_prone=yes
>          - hazard_type=landslide
>
> If there isn't risk of more landslides, you must omit the «hazard» tags.
>
> If only there is risk of landslide that not occured, there aren't
> objective obstacles in the trail, only a warning. In this case, I propose

>
>    - NODE or WAY with the tags:
>       - hazard_prone=yes
>       - hazard_type=landslide
>
> I hope I have answered your question ;)
