Two things.. 1. Phil - YAY - bundle adjusted references for all the sites in the top two txt files!!! And 2. Um....what does one do with those Bin's. Damn I wish I could code...if anyone knows a means to get that lot into any sort of appropriate 3D format they win the UMSF 'special cookie' award Just for fun - I bunged the XY data of MERB into Excel. It's not 'square' i.e. it's not accurate - but I think I'll go for something accurate in Photoshop Also - Z axis against Sol for Spirit...I've seen that graph somewhere else...but making it ones self from data is always much more fun - you can clearly see Bonneville, Missoula, West Spur and the return to Larrys Lookout.

Obviously there are artifacts in the Endurance DEM - so I've used a mesh density half that of the actual DEM to help cull some of that - after all there is a disclaimer on the page saying that once they get a chance to sit down and catch their breath they'll get these tidied up etc. Who knows...we might end up with one of the Southern Basin, or Victoria Crater
I think probably the most appropriate 'res' for something like this lies between the two densities...something like 1 million points is essentially 'plenty' Doug |

I'll try again tomorrow with something a bit more capable than Perl::GD. I'm still a bit confused about the big endian \ little endian thing though doesn't make much sense. |
