type navaid
name Foobar (Optional if object does not carry a name or you map
multiple different location)
source <object to reach> (Multiple ones sharing the same transport destination)
car <node to go to>
bicyle <node to go to>
foot <node to go to>
Just as the rough first version. You want to keep this to a minimum for
cases where an algorithm cant choose the right solution or is making
wrong decisions based on correct geometries.
A mall with parking south and north would get 2 navaid relations
name "Mall foo - North"
name "Mall foo - South"
With their parking lot entries as the nodes to go to by car
and their entrance for foot. Currently you might be lucky
that your Nav Software does a full text search and somebody
named the parking lots with the complete name although
they should only carry a ref=North/South.
So a navigation preprocessor would not try to find a node on the
routable network by algorithm but by hinting in case it finds
this relation.
It currently works by accident and because people tweak
the data to get their result. Either geometries, additional tags
or additional name tags on unrelated objects.
People start mapping for the router/nav software. A relation like this
could help solve the need of hinting the software without abusing
other tags, tag move, geometry tweaking.
