is to be copying directly from the NRCan paper map sheets (available as

So I just got a job that<BR>>
involves entering addresses<BR>>
into Google
Maps (don't ask),<BR>>
one of these streets, Drobot<BR>>
Place (all address in<BR>>
winnipeg), Google has
either<BR>>
deliberately or accidentally<BR>>
named Drobol Place (here,<BR>>
compare Yahoo, Bing, City of<BR>>
Winnipeg
Assesment, Google<BR>>
Street View (Needs Flash)).<BR>>
OSM makes the same mistake as<BR>>
Google, which
leads me to<BR>>
beileve that the street and<BR>>
others were copied from<BR>>
Google. I really hate
telling<BR>>
people that I caught them<BR>>
"cheating." (I'm sure it was<BR>>
an honest mistake) Could<BR>>
someone please
contact the<BR>>
editor responsible (you can<BR>>
look him/her up, I don't want<BR>>

be<BR>>
willing to help with any<BR>>
followup and cleanup, and you<BR>>
can give them my
username<BR>>
(sammuell) if you wish, I just<BR>>
can't bring myself to send a<BR>>
