i am mapping walking tracks in new zealand, and have recently added
'te araroa' - the walking track from the top of the north island to
the bottom of the south.
it is made up at parts of the way of other walking tracks, such as the
'coast to coast' walking track in the auckland region.
problem is, i can't get my head round how to relate the two in a relation
any suggestions? i'm using potlatch to do my editing, so examples
using that would be good
cheers
I don't know if it is possible with Potlatch to put relations as members
of a relation. It is quite easy on JOSM.
The schema of a relation type=route including relations type=route is
widely used on this program :
http://wiki.openstreetmap.org/wiki/WikiProject_Europe/Long-distance_paths
It is a way to split a very long route into several parts as for
http://www.openstreetmap.org/browse/relation/138227
If only parts of other routes must be included, the ways can be members
of several relations.
Some use a type=superroute for the main relations, but it is not an
existing type and it is not necessary for the route is simply a route
even if members are relations.
There is a good map showing the routes and rendering the osmc:symbol :
