Rationale
Provide a simple boolean property to classify a trail as being marked, wikipedia:Trail_blazing. This is to provide a simple tagging scheme, not competing with the symbol, colour attributes to Relation:route.
We need a simple tagging scheme, as several trails may not necessarily be part of a given route. Some regions may have a standard convention for marked hiking trails that may or may not be part of a route network, but not a specific route itself.
The proposal intends to replace the simple uses of Proposed features/Marked trail, but not to describe route specific trailblazing of routes, as these can be covered by Relation:route where colour=* and symbol=* can be used to describe route specific trail blazes.
Such simplified tagging will make implementation of consistent looking hiking maps easier.
Applies to
Any road, but especially relevant for highway=path and highway=track.
Usage, Tags and Values
Add trailblazed=yes to indicate that a way is marked using trail blazes.
Marked trails are often indicated on maps with various visual methods:
- Red lines or blue dots (conventions used in Norway).
- Colored lines - Purple markings == purple line on map (convention in USA)
Relevant mentions
Rationale
- marked_trail=* or any other tagging scheme is not established or widely used.
- implementation of marked_trail=* and relation:route:colour is combersome.
- maps implementing the actual colours and shapes may be noisy, and not generic.
- marked_trail="colourname" are insufficient in occurences where specialized trail blazes are made for a given route, which are more suitably mapped as a relation.
