Nick,<br><br>The problem you describe can be caused without the use of yahoo imagery or out of copyright maps. If someone surveyed a street in 2006 and it has since been made oneway, it will not be updated unless someone is keeping a close eye on changes made by local councils. If a country road is bitumenised, or a road is blocked for traffic management, or speed humps are installed, etc. etc.<br>
<br>Ideally all data would be derived from surveys and regularly re-surveyed, but until such time as OSM has amassed such a huge amount of manpower, old data is better than no data (to an extent.)<br><br>I think you should reconsider your notion of a street being "complete." Perhaps instead of "has a name" we should define it as "has a name and has source=survey and has been updated in the past 6 months". Currently there is a large emphasis on naming streets (as shown by the noname layer, maplint, etc.) but once all streets have names, the focus will shift. Currently I do not know of any tools to highlight streets which do not have source=survey, but I imagine it would not be difficult to do so. <br>

</div><div>HI Darren,</div>
<div> </div>
<div>Please excuse me for taking your quote a bit out of context but....</div>
<div> </div>
<div>My concern is if someone traces a road from Yahoo, and then it gets tagged from a source other than the street signs</div>
<div>then the road is complete but has never been surveyed.</div>
<div> </div>
<div>Yahoo hi-res imagery is sometime over two years out of date and roads that seem to be there are non existant.</div>
<div>Also these old directories don't appear to have any of the one way streets in central Adelaide marked as such.</div>
<div> </div>
<div>Therefore once they are traced and tagged, thats it, they will remain incorrect until someone using the Garmin</div>
<div>routable maps is directed up the wrong way. Then either that person will sign up to OSM, just to fix this road or</div>
<div>more likely will just say, Well OSM's worse than Sensis or PSMA and go back to the better maps.</div>
<div> </div>
<div>Morialta Street (near Victoria Square) appears to have already suffered this fate. There are no public gps tracks</div>
<div>so I can only assume it has been traced. Google street view, google maps and sensis mapping all indicate that</div>
<div>it is a one way road but to use this to add a oneway tag would unfortunately be copyright infringement.</div>
<div> </div>
<div>It will be interesting to see what happens to its neighbour "Trades Hall Lane".</div>
<div> </div>
<div>If necessary I'll try to survey all the one way streets in central Adelaide, but I won't be able to do it till</div>
<div>Christmas,</div>
<div> </div>
<div>Gawler Place is marked as one way for part of its length but google street view seems to indicate that it should</div>
<div>be one way right through to Grenfell rather than just Pirie. Next door Wyatt is missing its oneway tag.</div>
<div> </div>
<div>I appears that I'm going to be busy this december, but hey, it was the lack of marked one way streets (in Monterey California- Teleatlas mapping)</div>
<div>than really got me motivated to contribute to OSM so I'm more than happy to drive down the very smallest one way roads that </div>
<div>I can find. (Gotta find a hire car with a really good turning circle !!)</div>
<div> </div>
