(Added detail: One of the major methodologies in high-resolution radar mapping produces an image which reflects details over a line which is near the equator, so the result is not a flawless hemispheric image, but an image which shows the north and south hemispheres ambiguously overlapped, so that you can say with confidence that each feature so detected is either in the northern OR southern hemisphere, but you can't be sure which! This ambiguity can be eliminated with repeat observations, with slightly changed geometry, which will cause the overlapping to happen at a different angle, revealing which hemisphere a feature is really in. I'm not sure if this final step has yet been performed, but the conference abstracts describing the work do not mention the ambiguity problem.)
I imagine that optical data could help - in other words, if there is a bright feature with rays extending from it in one hemisphere, and there is clearly a well defined, young looking (not overlapped by anything) impact crater in one hemisphere or the other, the optical data could help resolve the situation. -------------------- |
