Re: [Tagging] Feature Proposal - RFC - natural=bare_rock
2011/1/28 Johan Jönsson joha...@goteborg.cc: My opinion is that natural=bare_rock should be used for solid rock and not for fields of stone/stony ground. The visible bedrock, even if it could be splintered and jagged. Okay, so this natural=bare_rock RFC should be used where there is one very large stone/rock surface in the ground, even when jagged, and not for loose rocks. I support this proposal then. The first proposal intended to span all kinds of stone surfaces, I changed that. I took a look at [[IOFmapping#Rock_and_boulders]] and got convinced to separate the solid bare_rock. In the discussion it was argued that natural=scree could be used for rough stony grounds, that maybe not the case as scree have a limited definition meaning a certain mountain slope filled with rubble, [[http://en.wikipedia.org/wiki/Scree Scree on wikipedia]]. There is a definition on [http://etc-lusi.eionet.europa.eu/CLC2000/classes/Pictures?CLCcategory=3/3.3/3.3.2CLCtitle=Bare%20rocks European Topic Centre on Land Use and Spatial Information] that is like the first proposal, encompassing all kinds of areas with visible rock. /Johan Jönsson I also think it makes sense to separate the solid bare_rock.

Sorry for diverting the thread if this is getting too off topic, feel free to reply using a different subject-- I saw scree on the wiki, your explanation helps. The kind of rocks I'm thinking about are on the coastline, not on a slope, and are not really at the base of a cliff. They are mostly stable rocks, but usually enough to walk on if you are careful, but can move. What tag should I use for this? I think it is different to scree.

OK, so IMHO this would be right to remain in natural: it is more about the geographical situation then about the material (or better: it is not only about the material, but it is a type of landscape-feature). Opposed to this, loose_rock would be a landcover-feature (and probably implied by scree).

Yes, IMHO (I'm not an English native) this is not scree.
