View 10GB .bin picture (in Matlab?)

  1. May 12, 2006 #1
    So I downloaded a NASA Blue Marble topografical image of Earth (2.4GB when I downed it, I decompressed and... wtf, 10GB+). Now I have no idea how to view the resulting .bin picture. I tried to somehow import the data to Matlab, because I heard that program can somehow do the trick, but it went 'hahaha, you seriously think this comp has enough memory?' or something (512 RAM, plenty of HD space).
    Searched the net for hours, still nothing.
    Maybe one of you has experience in the matter. Thx already for eventual replies.

    If you don't have PS, you can always try the GIMP, according to the File Menu it can open raw files too.

    The GIMP is a free download.

    I may come out as a fool here and forgive me for being so very ignorant, but am I reading this correctly - a 2.4 GB picture file? What format is this file in? And what resolution? PS I dont know a anything about MATLAB (u must have probably guessed that by now)

    Thank you for your efforts, none of the proposed solutions seemed to do it, I'm affraid.
    My search has lead me to some amazing software, NASA World Wind (check it out at www.worldwindcentral.com ), it's kinda like Google Earth, but you can download serious cache packs for offline availability. And the plugins are yummie (like they have data for other planets and stuff, or you can have links to the CIA fact files from every country pop up, too much to mention).

    Indeed man, a 2.4GB picture (.gz compressed, I understand that to be some super-zip or something) decompressed it is 86400 (pixels longitude) x 43200 (pxls lat.) x 24 bit colour depth amounting to over 10GB providing a picture of the world with just under 500m resolution. To get it, do a search for NASA Blue Marble, I suspect that will lead you the way.

    Still no luck viewing it :frown:

    .bin is an executable file, from what I know. Gotta ./ it

    .bin is a image file (CD DVD images that is) also...
  9. Jun 14, 2006 #8
    That's right too, but doesn't image .bin need also another file .cue to work?
  10. Jun 14, 2006 #9
    AFAIK no it doesnt, the cue will tell you where the tracks are on a CD for example but if it is just data u dont need it, the .bin holds the data the .cue contains track layout info

    I tried it a while ago, mounted it as a virtual disc (with deamon tools) (had to convert it to some other format first, that went ok). But when I clicked the drive... 'format not supported'
    I'll try renaming it to .exe (or ./ lol) but I'm not getting my hopes up with that, as it has a filesize that matches the # of pixels x colour depth, matches it to the byte; so I'm guessing it's raw data, with nothing else.
    I'd better wait a couple of years, till they have computers (that I can afford) with 16GB of RAM.

    by ./ I meant you gotta execute it, either by linux emulator or on any linux/or like systems.

    Antimatter, can you please post a links of a website with that file you've downloaded? I think that'd do half a job.
