Along with fresh, sharper imagery, you’ll now be able to look upward as […]

As you can see from the pics, it’s not perfect, but it does a reasonable job.

“Is that two light poles, or two columns sticking out from the building?”

I agree with your last statement — if anyone can do it large scale, it’s Google.

In the example 3D model I linked, the system strips out all the foreground clutter, and then fills in the holes in the building façade by interpolation.
No question that doing this kind of reconstruction on a large scale is a really hard problem. But it has been done for pretty large examples by the research group at Berkeley, and if anyone can make it work on the large scale, it’s Google.

I don’t have enough knowledge about the laser systems to be able to give a qualified answer. If I find out how that works, I’ll be sure to post it.
