I’m interesting in following this to see if anyone posts anything interesting, because I only know 2 so far:
The Nazca Lines in Ica, Peru:
14 deg., 42 min., 2.97 sec. S and 75 deg., 8 min., 25.74 sec. W
Weird lattice lines in Gansu, China:
40 deg., 27 min., 27.71 sec. N and 93 deg., 23 min., 0.41 sec. E
There’s more weird stuff in that same area around:
40 deg., 29 min., 16.57 sec. N and 93 deg., 29 min., 26.51 sec. E
Also in Gansu, there’s more bright white lines:
40 deg., 27 min., 9.5 sec. N and 93 deg., 44 min., 34.41 sec. E
I use DMS, by the way, obviously.
