Here is a constant-scale natural boundary map of Ida that folds to a decent replica of the asteroid. Map edges are Ida's major ridges.[attachment=16299:Ida_MaxRidge_post.jpg]
[EDIT] Here it is again with the photomosaic properly credited; apologies to M. Nyrtsov for my oversight. |

OK, I corralled a photographer, (S. Adkins) to take a pic of the folded map.
Here (on the left, courtesy of T. Oner)) is a digital image of Ida; and (on the right) the Adkins photo, taken from approximately the same point of view as the digital image. On the other hand, I think jumpjack is best to wait and hope that Tayfun will make a slices-infill. Two reasons: 1) IN GENERAL: These are experimental maps; folding up to make a convenient, holdable model is a nice property, but the maps are far from perfect (the technology at the moment uses -- to make outlines and graticles -- the very latest of Renaissance graphical techniques, and Photoshop to add the photomosaics). 2) IN SPECIFICS: With the exception of a few crania I mapped a while back, Ida is the most complicated form yet attempted in constant-scale natural boundary mapping, certainly the most extravagantly shaped asteroid. Something (on the back side of this view!) is a little amiss -- to kinked or cramped -- around point "n.". It's easy for the geometry to slip a bit, and the edge get a little out of alignment or true constant-scale; this is probably the problem. Printers can also be a bit out of relative proportional accuracy. So best to take this all with a grain of salt. |
