[OSM-talk] YOURS now supports route using only cycleroutes -Update

[Nic Roets]

AFAIK, ORS is not FOSS. Neither has Lambertus published his source, although
I believe it will eventually be done.

The gosmore / YOURS API is quite simple. Input is basically the permalink
URL and the output is a list of coordinates in CSV format. It includes info
about the segments such as way names and junction types e.g. traffic_signals
/ mini_roundabout. So YOURS has enough info to generate verbose English
output, but it's just not implemented.

Currently gosmore does not allow it's routing parameters to be changed
between queries. It is a feature that's easy to implement that Lambertus has
asked me for. It will allow different YOURS users to have different
preferences, which will be pretty cool, but I may not get time to implement
it before 2009.

If YOURS can allow users to manage many different markers, it will be easier
to tweak routes. For example forcing the route from A to Z to visit B and
see how much of a detour it is. It sound like basic OpenLayers stuff, but
neither Lambertus nor I are experienced enough with it.
