That's nice binary, but if dots are zeros then it is an OFF-by-one error.
Should be:
. . . = 0
. . | = 1
. | . = 2
. | | = 3
| . . = 4
| . | = 5
| | . = 6
| | | = 7
Which would then give you quadrant numbers:
2 . . . 3
4 . . . 1
[edit] not my pic.
just pointing out the off by one error.
using count zero binary, as I have, gives you a 1 to 4 labeling of the quadrants.
My theory is that this is a sequence of things that have to be done or found:
quad 1 has a line to the center. Perhaps a sub surface structure.
quad 2 has an arc above the surface maybe a ring or the blue landable indicator.
quad 3 looks like it's getting scanned
quad 4 has two structures coming out from the surface.
