I'm pondering the discrepancy between Ron Li's position for the rover and the positions shown on the JPL route maps. The problem is the difficulty of getting an unambiguous feature match between the two very different sets of images, surface and orbital. The JPL maps are basically done by a sort of 'dead reckoning' approach which can be put off the mark by wheel slipping etc. They need to be corrected from time to time by the OSU work.
Well, this forum would be no fun if we couldn't occasionally take a chance on a wild unsupportable statement... so I have somehow drifted to the conclusion that Ron Li is right, or almost right. I might be a short distance above (north of) his position. So I predict that the JPL map will be redrawn shortly to correct for this. And what about that new view? Amazing! This armchair Mars exploration is way better than real life. Phil -------------------- ... because the Solar System ain't gonna map itself.
