Currently the highest clarity civilian satellite camera can take pictures of the surface of earth with a resolution that takes 5 centimeters. (2 inches) per pixel.

So you won't be reading the text on a piece of paper. But you can loosely distinguish the piece of paper.

When Trump leaked those DOD images of the Iranian launch site people said it was evidence that the military had satellites that could produce images of .5 cm per pixel. Less than a quarter of an once.

Meaning they can read header fonts. But not quite yet normal typeface 12pt text.

That was 3 years ago.

I'm well aware Google Earth is its own thing. But back when this whole issue was super present in the news media. They did a whole news program on satellite images. And so long as the BBC wasn't lying. They showed a cat video as their main example of the best sat image to date.
