NETR Online has put together a nifty site to view several decades worth of aerial imagery across the US. The link was sent to me by our good friends at LizardTech to show the power of their Express Server which is used to deliver over 60 TB of data on this site.
On the left of the page you’ll see some points of interest links. Las Vegas has to be the coolest before and after imagery, albeit mostly black and white. You can also check out Manhattan and see before and after imagery of the World Trade Center buildings.
