Subject: [OSM-talk] Routing across parks
For example let's use parks. Both of the foot routers won't cross
the
park unless there's a specific path way. However, as users can
wander
about anywhere they like there are no marked paths, not even worn
ground. (I would post an example but OSM has just gone down)
If I understand correctly that you want routing to cross a park as
long as the way in and the way out are connected to the perimeter of
the park. This is only correct in parks where you are free to walk
anywhere. Most parks in continental Europe do not work this way.
Typically, but not always, you have to stay on the paths.
To solve this, one needs possibly a new (?) tag for parks like
stay_on_path=yes|no
Isn't it better to tag areas where you are allowed to walk with foot=yes
(when it is not already tagged as highway)? I don't know how routers
handle leisure=park or landuse=grass combined with foot=yes.
Are there routers that do shortest-path routing across areas? I do not
have an example of an area without additional roads ready.
