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. |

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? |
