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.

I've begun to make some progress - it's getting quite interesting Some piccies of Endurance later perhaps
Doug
Something definitely odd - the file labelled Motorola FP32 (Eagle) is actually littlendian and the Intel FP32 (Enfurance) is bigendian. Maybe it was just a test. Anyway as "grayscale" images - got to work out how to output the data with better depth resolution (these are true color pngs just using gray values so there's really only 8 bits of depth) which is about 1cm for Eagle and 10cm for Endurance. The data for Endurance isn't quite square but the error is only about 0.07% so it amounts to less than half a pixel over the full image so it's not noticable.
Endurance:
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
Nice work with that last one, Doug. I need to refresh my skills with this grid plotting software, as I didn't create anything as pretty as your view. I'm working with the ASCII files, since they are easily accepted by my software. I can see that there is quite a bit of detail in the data; now to learn to bring it out as you have. I tried a shaded relief map of Endurance, but it was difficult to make it look well, and it appears to have a strange network of artifacts. I wonder if that is some of what they hope to eventually clean up.
I found it curious that the ASCII file for Eagle was huge...60+ MB, while that for Endurance was relatively small.
I used the Ascii files with Surfer, but then 3dem with the bin files to generate a Terragen mesh from which I made a Tif which I used as a displacement map
There's what, 250k points on the End one, 7.29 million in the Eag one - so it's 30 times more data than the End one...not suprising it's a bit big.
I wondering if perhaps, just perhaps this little easter egg of data is in response to the email I sent to Prof Li a few months ago asking if he could do elev maps for us nutters
Attached - the dem at the best res I've got it into 3ds, and the res I actually use it at

6.6 Megish...

Not happy with the compression though - I'll try a H264 Mov at 720p and half 720p later
Doug
Beautifull work -- particularly nice with the overlay.
-- Pertinax
Very nice maps. The artifacts in the Endurance map must be caused by the interpolation routine they use to grid the data.
Phil
Great piece of work, Doug. In the video, it really becomes clear that the rocks from Escher to Wopmay are part of a slump feature. And it's possible to follow the contact between the Upper and Middle Units of the Burns Formation. Really cool!
