The sidewalk:both=* key is similar to sidewalk=*, but always express values for both sidewalks (or their absence) of a street.
sidewalk:both: is also a prefix for a set of tags that describe attributes of both sidewalks of a street. See the additional tags section of sidewalk=* for examples of tags such as sidewalk:both:surface=*.
It has seen considerable usage as sidewalk:both=separate.
Values
| Value | Description |
|---|---|
| no | There is no sidewalk on either side of the road. |
| yes | There are sidewalks on both sides of the road, and these are not mapped as separate ways. |
| separate | There are sidewalks on both sides of the road, and both are mapped using separate ways. |
Rationale
This key's most common value sidewalk:both=separate may express its intent more clearly — i.e., making explicit that a separate highway=footway is mapped on both sides of the street, whereas sidewalk=separate may be seen as covering both this as well as the case where a separate sidewalk is mapped on only one side without specifying which side.
Concerns for data consumers
sidewalk:both=* overrides any value set by sidewalk=*, but is in turn overridden by the more specific sidewalk:left=* and sidewalk:right=*; although mixing these is discouraged.
