I knew you were not going to sent the MER team "only" a postcard for the 3rd anniversary...
Very dramatic and beuatifull indeed, thanks. -------------------- |

Great animation djellison. I really like it a lot.
I never knew about the hi-res topography data on USGS, so I decided to download some of it for myself to play around with. I went and downloaded Victoria crater and it has everything in a .tif format (as well as the .cub files) and it all works except for the DEM .tif file. When I load it up in photoshop it's all black. I went and downloaded GDAL and loaded up the DEM .cub file and it shows up in there. I exported it as a .tif from there, but it still does not show in photoshop. Does anyone know what I'm missing here? |

I haven't tried to work with the DEM data at all, so this is a shot in the dark, but my first question would be: is the file 16-bit, and if so, is all the data down in the first 12 bits? That's one reason things can look black in Photoshop. Check Image > Adjust > Levels and see if the histogram shows anything at all.

The file is 16-bit. And the histogram seems to be blank.

Well that's pretty much all my ideas. Guess you'll have to wait for the Sun to rise on the UK

This is the only way I know - so far - and it's very long, convoluted, and I'm SURE there is a better way to do it - but it works.
1) Install ISIS 3 - instructions here http://isis.astrogeology.usgs.gov/document...uide/index.html 2) While letting that happen - grab one of Randy's DEM's - I'm using the Victoria Crater bundle as an example 3) Find DEM_1m_VictoriaCrater.cub.gz (it's in the ISIS_EQUI360_OC folder ) and expand it 4) Run isis2raw 5) In the 'FROM' window - point to the .cub 6) Copy and paste the path and filename into 'TO' - but change the extension to .dem or something simiar 7) U16BIT data type ( screenshot attached) 8) Hit Run.... if this bit doesn't work - it's almost certainly your ISIS3 installation that needs looking at, make sure you got all the Base Data. 9) Find the .cub and open in text edit and find this part... /* Core description */ CORE_ITEMS = (1278,1694,1) 10) Open Photoshop, and open the .dem.raw that ISIS3 produced 11) Width is the first of those three figure under CORE_ITEMS. Height is the second. Depth should be 16 bits, Byte Order as IBM PC, Header as size 0 12) Hit OK 13) Save out as 16 bit PNG, celebrate, have lunch, dump into your favourite animation package. I'm hoping to figure out a workflow that involved just ImageJ or Photoshop without ISIS3 (as it's a hell of an install, and a pain in the butt to get running for a temperamental artists like me ) |

Nancy talked about it on Universe Today, Emily did the same on planetary.org/blog
Has it shown up anywhere else? It'd be cool to know. I HAVE noticed that it's jumped to 9000 views on Youtube. I beat the 5000+ Helen got for her world record Thriller dance routine |

Has it shown up anywhere else? It'd be cool to know. Doug, I get an email newsletter called "Good Morning Silicon Valley," and I think it has fairly wide circulation. It's pretty pithy and as far as email newsletters go, entertaining. You were "Off Topic" for September 28th. Sorry I didn't mention it until now, but I thought you might know! Guess youtube does let you know the referrers. I noticed a twitter post of yours from awhile back. http://blogs.siliconvalley.com/gmsv/2009/0...-topic-344.html That probably got some clicks outside the usual enthusiasts. |

NASA Ames is working on a stereo pipeline for automated DEM generation: http://ti.arc.nasa.gov/project/ngt/stereo/
Their documentation has instructions for HiRISE. MOC and CTX are in there as well, although I will point out that their camera model for CTX is incorrect so any CTX DEMs created with this software are inaccurate. -------------------- Twitter: @tanyaofmars
