To answer Ustrax's querries from the other thread, I think we can now see more of the
The leftmost (Endeavour north rim) and middle (far rim) features look similar. But it looks like we can see more stuff on the right, which is Endeavour south rim and Iazu. The view we had a few sols ago (2133) of Iazu was still partly obscured by dunes, so it makes sense that we can see more now. I can't see Bopolu in the navcams, though it could be there and buried in the jpeg noise... |

Yeah I'm troubled by the lack of visibility around the marker point too. My gut feeling is that this is all coming down to the underlying HRSC DEM, which is 75 m/px. This is probably too coarse to do a viewshed at the scale that we're interested in. But I've got to admit that this is the first real time that I've played around with this method so I'm still learning the ins and outs. Now if someone had a CTX DEM of round here...
So I'm going to have a bit of a play around and see how things change as the marker moves around. I've got a feeling that I might be 'overinterpreting the data' as they say (ie making it up!). But the idea of moving around and averaging is interesting, and if I come up with anything then I'll put it up. I might even try a little bit of MOLA as well, see if that improves things, as that's what Tim Parker's LPSC contour map used I think. Pete |
