Late last week I stumbled upon a few HiRISE derived DEM's (Randy Kirk works his magic once again!)
http://webgis.wr.usgs.gov/ftphirise/index.jsp (URL now down) I'm working on both Vic Crater and the Columbia Hills. Fortunately, now I've got a Mac, I can use ISIS. I've figured out a fairly simple flow ( isis2raw as 16 bit unsigned, and then imported into Photoshop ) to take DEM CUB's and make 16 bit PNG's Just to demo how important that is for me as an animator - sliced comparisons of 8bit vs 16 bit. A busy week unfortunately, but animations of various sorts are in the pipeline. |

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

Care to elaborate on what is wrong with the CTX models? It might be an easy fix to send to the ISIS developers as our camera models are their camera models. |

I don't know what it is that's off, I was just told by the software folks at MSSS that there was an issue. Trent Hare is getting in touch with them to figure out what the problem is. -------------------- Twitter: @tanyaofmars
