I stumbled into this reading a Jane's email on Pictometry system ~ http://en.wikipedia.org/wiki/Pictometry for military use, measuring tactical details from satellite imagery. Taking oblique measurements is not something I've heard about before.
interesting bits:
"... Where satellite imaging and orthophotography show the world only from directly overhead, making everything appear flat, the Pictometry system shows the world at an oblique angle, providing perspective. And they include an overhead shot. ... Images are accurate to 1/100th of an inch and evaluators can measure lot lines within the system. ..."
"We do all the R&D ourselves, which really gives us the leg up on everyone," said Dante Pennacchia, Pictometry's chief marketing officer. "If you can manage your own software, find out what the customer needs and create the solution to it, you're always going to be in great shape."
This idea mirrors the startup mantra: "make things that users want" in software.

Another article mentions the resolution at about 3" per pixel with the ability to 1" per pixel. This is enough to ID faces (if they look up) at the time of capture. ~ http://www.signonsandiego.com/uniontrib/20061008/news_mz1h08...
