Eye in the sky

6 Oct 2004

I guess I’ve known about aerial imagery available on the web for a while now, but recently I came across a surprisingly clear photo of Dupont Circle, linked from a post on Michael’s site, that suddenly made me aware of the quantity and quality of land images out there.

I’ve been playing around with the USGS “Urban Area” data set on TerraServer, and here is a quite recent photo (Feb. 27, 2004) of San Francisco International Airport at 4-meter resolution. (Each pixel represents four meters.) So there you have the parking garage in the middle, surrounded by the terminals. Almost kind of artsy, don’t you think?

And here at 0.25-meter resolution is the open hub of the parking garage. Ooh, taxis!

Cool.

Check out this ultra-cool overlay of a street map on an aerial photo of London (I was going to Dude it, but Dude seems to be down at the moment).
