“Objects about 25 centimeters across are resolved on this image spanning about one kilometer”
I hate when they use these measurements because I have no idea what they mean. I cannot get any idea of the size I am looking at.
And their explanation, although I’m sure correct, does not seem correct. The dark stains appear to be standing freely in the air and do not look at all as if they are sliding down a sand dune.
Useless to me.
Interpreting overhead photographs requires a rather long school in the US military.
Lots of pitfalls and tricks to it. What you think you see might not be reality on the ground.
