Proposal

A key for tagging areas made principally or mostly of solid rock.

It is supposed to map the landscape type or the surface characteristics in areas where the bedrock is mostly uncovered leaving large areas of bare rock in big slabs or as a featureless area. It could be smooth or rugged with cracks and crevasses and do not imply any special class of passability. It could be plain or leaning, when it gets too steep consider natural=cliff instead.

The area should have little or no vegetation (sparsely vegetated areas where 90 % of the land surface is covered by rocks).

Pictures

A coastal area of bare_rock

Here are some examples of coastal areas that could be tagged with natural=bare_rock: Limestone field, Point Lobos, USA, A small skerry.

Some examples of monolithic mountains Cerros_de_Mavecure (http://www.openstreetmap.org/?lat=3.46842&lon=-67.97034&zoom=15&layers=M on OSM] where it is obvious that there are parts that not are steep enough to use natural=cliff as an area.

Not to be confused with

  • natural=scree - debris fields or other areas of loose rock.
  • natural=stone - natural boulder or rock fragment that is not attached to the underlying terrain.
  • natural=cliff - steep slopes and precipices

Tagging

Rendering

A light grey area. With alpha, so you can still see the hillshading

History of the proposal

  • 2009. Originally proposed as natural=rock by user:Cade. It was meant as a quick way to tag areas of mostly rock. Discussion acc.to talk page showed that the word rock could mean many things.
  • 2010 It led to a rewriting of the proposal to natural=bare_rock.
  • 2011 January, RFC sent to tagging maillist. Discussion on landcover=bare_rock instead and how to tag loose rock that is not scree.
  • 2012 July, RFC sent to tagging maillist because fo the tag already beeing in use.

  • I approve this proposal I approve this proposal. Ceyockey 02:34, 26 July 2012 (BST) — good formalism for de facto tagging standard.
  • I approve this proposal I approve this proposal. Except for the note on cliffs. I don't consider natural=bare_rock and natural=cliff mutually exclusive. bare_rock is an areal feature, while cliff is a linear feature, specifying a line where you can fall down. If a cliff is a closed line, it is still not an area, but just a cliff that goes around. --Fkv 14:21, 30 July 2012 (BST)
