This one (attached - Arsinoes Chaos ) and a very long-noodle of Olympus Mons rendering now.
These things usually have an ND image of 12.5-50m/pixel, 4 colour images of 100-250m/pixel and an elevation image, usually of about the same res as the colour, perhaps slightly lower. Most of the time I drape the colour over the ND to super-res it. With the Ol. Mons one, I thought "Do I drop the colour over the higher res ND filter?" Then I discovered the ND is 17568x144800 - That's a full HiRISE image sort of filesize, and the HRSC to Tif convertor has to load the whole image into ram. So that's a no for now On the upside, I should be on 8 gig of ram by the end of the week (dropping 4 more in) I want to do Elysium Mons, but the DTM is so soft it's a bit dull really. Doug |
