I got this through a friend and thought it to be somewhat important to this thread. For those of you like myself that have to E&E from urban areas.
All:
Very interesting technology.
Exercise one: If you look at the picture and figure that you are part of a survey team, you will look up high on the balcony. Amongst those watching the crowd, find the two Sikh gentlemen. One with a purple turban and the other with a black turban. They are not doing anything wrong, just enjoying the view along with some of their co workers.
Now click View All so that it takes you back out again.
Exercise two: Look down at the lower right corner and find the male bike rider wearing a bright red jersey. Look at all of the shenanigans around him. Torsos without heads. Jeans with nothing above them.
Exercise three: Look in the windows in the nearest building to the right. Find the "Solidarity" poster. OpSec. Remember your computer screen angles and window angles onto your desk top computer, etc...
This picture was taken with a 70,000 x 30,000 pixel camera (2100 Mega Pixels.) These cameras are not sold to the public and are being installed in strategic locations. The camera can identify a face among a multitude of people. Place your computer's cursor in the mass of people and double-click a couple times (or 'finger-spread' on a device.) Scary sharp!!

Once you get to the link above you can move around and zoom (super zoom) or zoom out. In one spot down low to the left of the bicycle rider you can also find a guy holding a smartphone. I'd say if you are watching realtime you could see him dial a number just using thumb movements on a known device.
Have fun! Orwell would not approve.
