|Tools for this tag|
An area of bare rock is sparsely vegetated or not vegetated at all, so that the solid bedrock becomes visible.
Areas to tag could be
- high altitude mountain areas where the rock lays bare, like summits, aretes and rock faces, but not scree, shingle or moraines.
- rocky coasts
- rocky areas in uplands, desert and polar regions
- outcrops like open pit mines or road cuts
- monolithic mountains like Uluru (Ayers Rock).
How to map
To map an area of bare rock you can just draw a line closing on itself, marking the area as bare rock. To map larger or more complex areas you can use Relation:multipolygon with the same tag.
It can be mapped as a node (if there is no way to map it as a geometry), especially when someone wants to map name or some other additional properties. But mapping as an area is strictly preferable.
- natural=cliff - steep natural drop in terrain topography
- natural=scree - loose angular rock fragments formed by rockfall and weathering from adjacent rockfaces
- natural=shingle - rounded rock fragments on a beach or riverbed, deposited and shaped by movement of water
- natural=stone - large boulders (glacial erratics or rock fall) not attached to the bedrock, mainly single node element
- natural=rock - isolated, notable rock features connected to the bedrock, mainly single node element
- natural=glacier - glacier areas
