Hoping someone can help.
I am trying to uncompress the FMAP .img files which are part of magellans images of venus so I can use a converter program to convert them from sinusodal to cylindrical mapping. Things I do know is that I can just rename .img to .raw and open in photosho however the converter program newmap.exe which is an old dos program that is provided with the FMAP images requires I think the uncompressed .img files in order to convert sinusodal to cylindrical. I know the .raw didnt work. And I get error saying my .img files are compressed so it wont work. I know .img files are not cd or dvd image file or so I think becuase I could not open them in MagicISO If they were CD images I would think MagicISO would work but I may be wrong though. Anyone familiar with what I am trying to do. Any image processing guys out their do this with the magellan FMAPS? I figure the experts would be here. thanks |

early on i liked pds-map-a-planet
for the simple reason that i had NO CLUE what to do with a .img, or .imq or .pds and on Windows at the time ( pre 2004 ) the software was very limited , still is. at the time i as just switching from the photo darkroom to the computer so i had a bit of knowledge of digital images now years later ( and still "learning" ISIS3 /IDL / other programs ) -- it is like the game "go" 10 min to learn and a lifetime to master . --- now it is much easier to import ( say fl73n003new.img) into isis3 and make a map file and remap |
