Wow: ESA Image of the week (http://www.esa.int/esaEO/SEMHS2MVGJE_index_0.html). Sorry if it's been 'ToSeeked' already but this angle from a satellite? i'm impressed!:cool:

How in the world did they manage that?

I'm still not sure, I keep reading the article!

I'd guess they built a 3D model of the shape (in a computer) since they are able to gather altitude data. Then they skinned that 3D model with a 2D image of the area, and then mathematically tilted their 3D model to get an oblique perspective view for display.

Any idea what the resolution is on that pic?

I believe the technical term to describe that picture is "SWEEEEEEEEEEEET!!"

I think 0110101 is real close to the mark on how it was assembled. On the other hand, if that's an unmanipulated image, that is about the most awesome shot I've ever seen from a satellite (makes you wonder what the boys and girls at Vint Hill get to play with).

Its possible a perspective like that could be done on a lateral shot, as opposed to directly overhead, but that would be a neat trick.

Yeah! What 01101001 said. It's similar to what ESA has done to Mars. Amazing somebody thought to do that to Earth! And the article said this was its first image. I can't wait till this thing has been around for a year.

01101001 is generally correct. ALOS includes a stereo imager. That sensor allowed a digtial elevation surface to be constructed and then "draped" with the high resolution imagery.
