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.

That's exactly right, Chuck.

That's exactly right, Chuck.
Phil Good. Thank you. Seeing no gap between the two pairs was confusing me. My architectural eyes were trying to imagine four orthographic (boxlike) views. Now, (Sorry not to have put the whole idea in one post), it looks like the contact spot of two (paired) ellipses is a point common to both hemispheres. Can you nudge the two ellipses together, creating a little overlap, a shared, central region? Seems like this might work for a distance of, say, the middle third. If not the middle half. Not that I don't like them this way! They're fun to cut out and fold together into elliptical Itokawa "coins." |
