Just for fun - but scale is correct - a couple of simulated HiRISE views of what Oppy would look like if she continued to head north, stopping at some scenic points along the way...

Nice post about the current mapping strategy at Lenda's blog.
Also some new maps, which split Shoemaker ridge into "A" and "B" (we're currently near B ). |

Neat. Does anyone know a public source for the topo map in Matt Lenda's late blog entry?

Neat. Does anyone know a public source for the topo map in Matt Lenda's late blog entry?... Bill: I, too would like to find a source for that topo. We sometimes see some versions of that map at the Where are the Rovers now link at the JPL rover site. The OSU site is not very helpful in this regard.-------------------- ...Tom

QUOTE Here — context image! Take it! You'll need it! Matt: If you are going to post an image supporting a discussion about the need to find north facing slopes, you should either put a north arrow on your map, or you should follow the convention of making maps which have north at the top. Just a suggestion to make it easier for the rest us us to follow your line of reasoning. -------------------- ...Tom

I wasn't able to find an "OSU" on the Web. The entity OSU is apparently a loose university consortium of photogrammetric genuises and GIS geeks and not a physical brick-and-mortar organization with a receptionist and front office. I suspect that they develop maps and charts on an as-needed contract basis.
But this is standard photogrammetric work, developing topo maps from stereo pairs. The hard part is making the grid of elevations from the aerials, but this work is done with the contours provided on the map. I'm retired but can probably call in favors on powerful gridding software-- once the elevations and map control points are entered into an autocad-like file it would be trivial to generate one's own topo maps. This can be a lot of work, but do-able as a hobby and I may try it for grins and giggles some day. Thanks to Matt for sharing this with us, and I surely wish we had a similar topo map of the adjacent area to the NE... --Bill -------------------- |

OSU - Ohio State University, where Dr. Ron Li and his group have been involved in rover location finding and mapping since the start of the mission!

Yes, I saw Li's CV and know what OSU is and later found http://shoreline.eng.ohio-state.edu/ and even found this:

It looks like we're continuing our slope survey with another good drive NE on 2744. Although judging from this hazcam:
http://qt.exploratorium.edu/mars/opportuni...0M1.JPG?sol2744 you could be forgiven for thinking we've been transported back to the smooth terrain around Victoria! |

63m NNE, actually.
And, well, I think this navcam gives the same impression too: http://qt.exploratorium.edu/mars/opportuni...JMP0613L0M1.JPG |

Interesting feature coming into view for Oppy now...
And stretched... At first I thought that might be the more northerly parts of CY, but looking at Google Mars I'm now wondering if that dark tongue of material is actually darker ground sloping into Endeavour on the northern side of Artemis Crater..? -------------------- |

I'm thinking (tentatively, I've been turned around a lot lately) that the line of dark rocks in the upper right of this Navcam marks the near rim of the "summit crater" and that crater extends off to the left.
Sol-2744 Navcam: http://qt.exploratorium.edu/mars/opportuni...JMP0613L0M1.JPG That being the case, we are in the middle of the CRISM clay area. The soil at our wheels is quite different and remarkable, as seen in the Pan-, Nav- and Hazcams. T'would be a perfect opportunity for a "systematic foreground" image... --Bill -------------------- |
