>From the dates, it looks like most of those are from the Haiti earthquake tracing, when Google allowed OSM to use its imagery for tracing.

I have discovered a lot of data in OSM that appears to have been<br>
copied from Google Maps. See<br>
<a href="http://taginfo.openstreetmap.org/keys/source#values" target="_blank">http://taginfo.openstreetmap.org/keys/source#values</a> and type "google"<br>
into the search box. There appear to be over 30000 objects in the OSM<br>
database copied from Google. Anyone willing to help delete data and<br>
warn users? (It is a LOT of work to do this myself). Please beware<br>
that some of these objects may have been modified by innocent users<br>
afterward, please check the history to see which user originally added<br>
it.<br>
