Gfad, I'm inclined to think that those repeating shapes are the after effect of image editing.
Whenever you use a program such as photoshop to edit an image, say, if I was editing a picture of a model's face to remove a pimple, I couldn't just
paint over that pimple with "flesh" color - that would be instantly obvious, since the texture wouldn't match. What I *would* do, would be to clone
an area of the image that is roughly the same in hue. When you do this, with a "magic wand" type tool, you select a starter point, and then you
start to paint, and the two brushes move in parallel, magically erasing the pimple with skin-toned and textured pixels that *isn't* obvious. Later
versions of photoshop etc have perfected this tool so it works even better.
But say, for example, when doing this I picked an area of her face that had a mole on it. The mole would be repeated over and over in the small area I
was painting, a common mistake if you're a new user.
See, if you look at the image you posted, not only are the shapes repeated, but there are shapes near them that are also repeated.. Classic mistake..
You've accidentally re-cloned some artifact from your original "clean" area of the image..
It's something I've done many times by accident, and had to fix, when editing an image. (Photoshopping things is a hobby)
The greenland one is weird.. measures about 2 miles by 25 miles..
What would cover that sort of an area? Only thing I can think of is something like a runway?
