Found an instance where OSM spelling doesn't agree with NRN spelling, but does with other map vendors, submitted by the above person. In Valemount, BC, NRN has a road in triangular shape called Beavan Crescent, while 8th Avenue terminates at Ash Street. The above person got the correct triangular shape, but misspelled the road as Bevan Crescent. Interestingly, all of Google, Bing, Yahoo and Mapquest agree with the user's spelling and conflict with NRN spelling, but they all conflict with NRN/user's geometry.<br>

<br>Meanwhile, Whitepages confirms the NRN spelling of the road.<br><br><a href="http://www.whitepages.com/search/FindNeighbors?street=830+beavan+crescent&where=Valemount%2C+BC">http://www.whitepages.com/search/FindNeighbors?street=830+beavan+crescent&where=Valemount%2C+BC</a><br>
<br>It's hard to say who's correct in this situation. Would be nice to have more mappers on the ground who can go to the road and look at the street sign. Perhaps a misspell in the sign led to the mapping companies differing from NRN?<br>

it's within 10meters, then it's still acceptable (as thats the GPS standard,
when no other sources are available).<br><br>Since GeoBase roads just has the
basic linework is available. The solution would be to also convert the
GeoBaseNRN data for Manitoba, then have the .osm files open in JOSM & adjust
the OSM data to fit the GeoBase road network geometry.<br>And the other solution
is to be copying directly from the NRCan paper map sheets (available as
PDFfiles). they just need to be alligned with some identifing points (the
sheets have corner coordinates on it) and matched to JOSM points. (i used
Garmin MapSource to make a waypoint at the exact corners of the sheet to get it
lined up) <br><br>A manual process, but if it's done by local people while
adding more details, it shouldn't be that
hard.<br><br>Cheers,<br>Sam<br> </div>

one of these streets, Drobot<br>>

winnipeg), Google has
either<br>>

OSM makes the same mistake as<br>>
Google, which

beileve that the street and<br>>

someone please
