Having a bit of time free I have embarked on a new global photomosaic map of asteroid 25143 Itokawa. Follow its construction here as I go. I'm hoping it won't take more than 4 to 6 weeks as other duties call. The mosaic will eventually go into PDS.
This follows the work I did on a map made from rendered images derived from Bob Gaskell's shape model. That had to be the first step because the control I'm using is derived from published lat-long grids superimposed on his rendered images. Now each individual image will be reprojected to fit that map. The large local relief will make it impossible to make all seams invisible, however. First step: the north polar area. The outer edge is at 40 N, with 90 N at the middle and 0 longitude at the top. Phil -------------------- ... because the Solar System ain't gonna map itself.

Yaaaay Phil! I can't wait to see this come together. After I assembled Chuck Clark's cut-and-assemble model, I tried to identify the named features on it but made almost no headway at all; it was too hard to figure out what was being named on the photo map, even using the stuff from the USGS nomenclature page and map. I hope it'll be easier to figure things out with your maps. The large smooth area on this image is Sagamihara regio, right?

Emily, is the lack of lat long lines on the pictures the root of your problem? I've got lat longs drawn on my plastic model, so -- as I'll be popping Phil's new mosaic onto the foldable map -- I should be able to locate all those features at the same time. Didn't know you've had trouble; speak up next time. Let me tell ya, drawing the lat longs onto the plastic model was a J O B! Things get verry complicated around the neck and chin. But now, it's fairly routine to locate a feature on the plastic model and then find it on a map, cylindrical or other-style. One question -- what happened to Woomera Regio? Did that become Arcoona Regio? Phil, if it's not too much trouble when you finish, please post (or send me directly) a larger-size file. Otherwise I'll again pixellate in those areas where your image greatly enlarges when it transforms to my constant scale natural boundary format -- the chin and neck particularly. |
