That small crater we were talking about to the east on sol 3369? That's crater "Charlie Brown" apparently. They did a drive-by of it on sol 3371.

Sol 3374 complete panoramic :
 We can see a lot of features like Cape York, far away, to the left, Cape Tribulation which became visible due to the drive estward, and of course Solander Point.

Finally! A full panorama. Here's a circular version of it.

Nice! FWIW, this drive was about 50m SSE.
Map update soon... Edit: Even with this 360º mosaic I'm finding really difficult to correlate it with the HiRISE background. No clue.

Right - we've never had such a difficult place to work with.

True. I still remember how easy it was while travelling by the dune seas.

Yes, see what you've been missing on vacation?
That is, mostly eyestrain.Here's my guess on the color map. |

Yeah, this may be the toughest site to localize yet.
In extreme situations like this, I wonder how hard it would be to turn the 360 navcam mosaic into some kind of equal-area-ish projection to be able to compare more directly with the hirise view. Of course it would only be approximate, due to the surface being not exactly flat. Also, you'd have to estimate the scale based on the height of navcam and angle of view below horizon. Even with the inevitable distortions, shadowing effects, and scale error, it might still allow you to pinpoint the location by blinking between the navcam and orbital views and shifting one until you find good agreement. The distortions would be worse farther away, but maybe you'd only need to go out 30 metres or so to get a good match. |

That is what the professionals do. Best results, of course, if the reprojection is controlled by a stereo model from the Navcam stereo pan.

Ah, yes, that's much more convincing. I've updated my position to match Phil's.

Yes, I think that's it. And in this case this position fits quite well with the one calculated by the rover itself.

The rocks are layered like so many we've seen before, but they look like very coarse-grained, gritty layers here. Phil -------------------- ... because the Solar System ain't gonna map itself.
