Ok these guys have worked it out. I love stories of social media hijacking channels for their own purpose. 
The story:
Proposal 2.0
Michael Weiss-Malik, a Google employee, deserves a lot of credit for this one. What better way to show the world your love than displaying it on Google Maps? Weiss-Malik got his buddies on the Street View team to give him a heads-up on the next time the Street View car was coming out to take pictures. And when that day came, he was well-prepared, holding a banner that read “Proposal 2.0: Marry me Leslie!!” (see above) After that, all he had to was lure Leslie into loading Google Maps and zooming in on the precise coordinates of his romantic stunt.
Now, that’s clever.
The street view team are the guys taking photos and matching it to the mapping software so you can see actual photos of the place, not just 2D maps.
