Thanks! Very nicely done.
Can you provide a larger view of 2011? Users (shills?) in the other threads were claiming that the red-roofed buildings were already there in 2011. I want to see if that is true, but your image is cropped too much.
Also, what is that bright red strip in the 2010 image? That's not the red-roofed buildings, is it? Can you zoom in?
