[Strategic] Fw: Routing on OSM

[Milo van der Linden]

It is my personal opinion that routing should not be something the
foundation will facilitate. Why? Because it will ask a lot of the hardware
and it is not part of the OpenStreetMap foundation mission statement.

There are a lot of routing initiatives with openstreetmap, some are
commercial, some are opensource, some are considering to one day become
open. Besides that, pgrouting, the postgresql/postgis routing engine is
picking up speed and as opposed to gosmore, pgrouting is ready for
turn-by-turn navigation, but it also can handle travelingsalesman, A* and
other advanced routing techniques. I often asked myself, why are there so
many routing initiatives and why aren't they joining forces to create one or
two kick-ass routing systems? I cannot figure it out.

A role the OSMF might take is see if there are sponsors particularly
interested in providing funds for routing, then facilitate in bringing
developers together and let them work something out with only one real
demand: That the routing-engine is completely opensource. But as I said
before it doesn't fit the OpenStreetMap foundation mission statement in my
opinion.

Last time I dug into the gosmore fileformat, I noticed that it doesn't
maintain reference to openstreetmap way id's, this makes it impossible to
look up streetnames that could generate output like "go straight on 5th av
for 3 miles, turn left on central square, go straight for 1 mile on 12th
street, turn right on main". gosmore simply generated one linestring. But
this was 6 months ago and things might have changed.

Anyway, my answer would be no, and I would prefer if we can look into
getting strategic up to steam on more foundation related matters first.

Kind regards,

Milo van der Linden
