[Talk-ca] Bus maps for Ottawa

[Pierre Béland]

Mike,
Waterloo license is based  UK Government's Open Government Licence and is considered as a true OpenData license. It is not the case for all canadian cities and governments. For my city, Saint-Jean-sur-Richelieu, the data is available but the license is to restrictive. I will have to negociate with the city before using it.

Talking of quality, I was thinking about the coordinates precision wich may be, for some databases, very approximative depending on the method used. It is best evaluating before we use these.

Buses routes essentially consist of ways describing the route and nodes describing the stops.  The tags may describes specific platforms or route. In the relation, it is also important to indicate the role for ways and nodes.

wiki page http://wiki.openstreetmap.org/wiki/Buses describes the node tags and relations. As it is said, we have a relation for one direction only.
wiki page http://wiki.openstreetmap.org/wiki/Relation:route provides also valuable information.

For each city, it also links to a wiki page describing this city route relations. There are numerous examples that help to understand the process. I suggest you should add your city when the work is finished.

There are various ways to document. A nice example is city of Toulouse in France were routes are grouped by various type (ie. metro, bus, etc.).

I've heard that the shape data RoW provides may not be of great quality, so I suspect it might take me some time to do this properly.

>>>I was looking at Helsinki for solutions to a lane mapping problem (how
 to map left turn lanes), and noticed they have bus routes specified as relations on the road segments. This put me in mind of Ottawa. My first thought was to check on copyright issues. I learned that Ottawa has an open data policy (catalogue at http://www.ottawa.ca/en/city_hall/statisticsdata/opendata/info/index.htm). Talk about an embarrassment of riches! Now I just have to put the tools together to do bulk mapping to OSM.
