Key:visibility

visibility=* is used for publicly visible devices or objects or features to evaluate the scope of their visibility.

Values

Values denoting visibility of an element

• visibility=house: Visible from the pavement, or up to 10 meters (around), or to indicate that the device is targeted mostly for pedestrians.
• visibility=street: Visible from the current street, or from between 10 m and 50 m (around), or to indicate that the device is targeted to passers-by moving with vehicles going slowly.
• visibility=area: Visible from several directions, or from more than 50 m (around), or to indicate that the device is targeted to passers-by moving with vehicles going fast.

Values denoting visibility along a way

Commonly prefixed with the kind of path the visibility relates to, such as trail, track, path, trailblazed.

Tag	Trail	Requirements	Example
*:visibility=excellent	Unambiguous path or markers everywhere	None, orientation unproblematic, no map required	Thumb Thumb
*:visibility=good	Next marker always visible, but sometimes has to be searched for.	Basic sense of direction, map recommended	Thumb Thumb
*:visibility=intermediate	Track mostly visible	Good sense of direction, map required
*:visibility=bad	Path sometimes invisible, route partly pathless	Basic skills in orientation
*:visibility=horrible	Often pathless	Advanced orientational skills	Thumb
*:visibility=no	Mostly pathless	Excellent orientational skills	Thumb

Common combinations

• advertising=* For advertising devices, setting a 'visibility' value helps define the impact of the advertising unit on the passers-by.
• amenity=clock From which distance can you read a publicly visible clock? E.g.: the value 'area' can be used for a church clock.
