Proposed features/surface unification
|Definition:||description of road surface and its usability|
|Rendered as:||various road types|
This proposal should improve the current usage of the surface=*-key.
It is needed because surface is currently a mix of fastness and material types.
The fastness should go to surface:paved=* and the materials should go to surface:material=*.
With surface:condition=* we are trying to describe the status of the surface with less subjective values than smoothness=* does.
It should extract the best of Proposed_features/surface_values and Proposed_features/more_surface_values.
If it gets widely used by the community it could later replace things like Proposed_features/Smoothness and Proposed_features/grade1-5.
See the already used keys surface_material and surface_state on tagwatch!
- surface=* values are very inaccurate!
- tracktype=* has hard to distinguish values!
- smoothness=* is often misleading and emotional! See Proposed_features/usability!
To be added
- ways (roads)
- areas (places i.e. pedestrian)
- relations (type=route)

Values for surface:paved=*:
Values for surface:condition=*:
Values for surface:material=*:
|asphalt||everything made of bitumen or tar||AKA bitumen, tar, tarmac (tarmacadam), asphalt_concrete, asphalt_cement|
|concrete||Concrete based roads||Would also allow you to tag reinforced_concrete, giving the tank drivers amongst us some useful routing information.|
|cobblestone||Cobblestones and other similar surfaces||?|
|plank||planks and/or logs||Most commonly in bridges or similar strictures, but also found in some roads where the need to anchor the surface or increase ground force of the vehicle to prevent it from sinking into the ground. Also boardwalks, wooden piers, elevated footways through nature preserves.|
|dirt||Dirt, small stones||This would be the obvious candidate for transferring surface:paved=no to|
|sand||Sand, or fine surface dirt||?|
|grass||Assumes the grass length is still short enough to be navigable|
|bulldust||very, very fine sand (think talcum powder)||Very different from sand, bulldust can be difficult to drive through, as the vehicle tends to sink into the harder surface 6-12 inches below, without any idea what is below the surface. This is a fairly explicit Australian tag requirement|
|ice||road made only from ice with no underlaying structure||for normal roads with ice on them use surface:iced=yes|
|plant||gras, grain, flowers||?|
|soil||generic value for dirt, sand, bulldust, ...||?|
|user defined||materials not listed here||?||none|
