Let's look into others' perceived privacy from a viewpoint several km away.

you have no expectation of privacy in a public place, even when you're NOT in China.

Being IN China (should be clear from comment history, don't understand that capitalisation of 'NOT'), I do indeed get the idea a public space is a public space, a Public Security place. And there's lots of observation, indeed, though mainly passive.

Buying a high-rise apartment includes many incentives, not just the colour of the plaster of the wall and compound security, which many of these Shanghai high-rises over on Bund side have, but, for many friends and colleagues that purchase one, that is is indeed a private space that should not have someone's camera pointed at them.

Anecdote is anecdote though. As is assumption.

By looking at the river you can notice a moiré pattern with lines both horizontal and vertical to the camera, although the vertical lines are more apparent. I figure these would be either artifacts from the stitching process, or limitations of the lens itself. The effect also correlates in size and shape with out of focus areas, which can likewise be found in the river, signaling that it is indeed an artifact caused…

When you clear the cache or visit the site for the first time and zoom in, you can see the tiles load. These lines are at the stiching borders, and coming from the stiching algorithm.

Lens/sensor limit moire looks very different when compared to this.

Earlier quoted context omitted.

Why would that be manual and not an artifact of movement between snapshots? If it were manual effort,why wouldn't they erase a duplicate?

Look at the barges I mentioned ( https://imgur.com/a/ZNaLCuO ). Clearly this specific case isn't an automatic stitching of photos. We must agree that there is only one barge and, though not copied, one instance of the boat has been moved out of line from the other. It would look ugly otherwise. > Why wouldn't they erase a duplicate? This I don't have a good reason for, which is why i thought this was curious

> Why wouldn't they erase a duplicate?

IMHO to make the scene look more dynamic.

These gigapixel images are an extreme kind of landscape photography. None of these people are directly targeted in this photography.

Even street photography doesn't target people as-is. They become objects, they are stripped from their identity. They are part of the picture only.
