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. |

When I first popped the pathfinder pan back over the pathfinder dem.... I swore quite loudly.
"**** off, no WAY is it going to match that well" And it did. I'm trying to improve it with an HRSC or CTX image as a virtual table-cloth under the place-mat that is the HiRISE dem. Sadly - the HRSC DEM of that site isn't available ( as far as I can tell. There were two observations on that orbit. 3147_0000 and 3147_0001 gues which one's pathfinder. Now guess which one's got a DEM available on ESA's PSA... yup - the OTHER one) |
