Never mind. Nasa separated the huge scans into eight hi-res jpegs that fit together to form the whole Earth. Page ten of this pdf: http://veimages.gsfc.nasa.gov/7102/bmng.pdf explains and shows the graph. Hahah! Never mind.

This is all fine and nice as long as the image fits in memory, but once the image is bigger then that you need smart software. Photoshop has handled this issue from day 1. It only loads squares that you have on screen, and when you zoom out it only gets the scaled part into memory. Ofcourse at some size point the pixel no longer has a unique address. For 32 bits machines this is 4294967296 pixels, that's a 40000 x 50000 pixel RGBA image. I guess.

Time and again when trying to view these high-res scans in Blender or Photoshop, all i can view is part of the lower tip of Africa, some ocean around it and then Antarctica below. This really SUCKS! I'm beginning to think that Nasa is saving these high-res pictures in a faulty way. I am very frustrated with the failure of the larger resolution images to display correctly.

I spent an overnight downloading the July dataset only to discover that the GIMP crashes when you try to open a enormous images like this! I had to open it in Photoshop on my father's computer:(. I guess that it is due to the GIMP's idology of catering more to web design rather than digital photography (where 10000x10000+ images are not all that big). We can only hope that they will fix the problem. However, I have not found the really high resolution Blue Marble data to be too useful anyway. It is fun to look at, but it is really too big to be used as a texture for a planet, but it isn't high-quality enough to be used for any close-ups. For close-ups, I have actually found that Yahoo maps, amazingly, has the best data. They have 1m color resolution satellite data for the whole US (I think). Unfortunately, it is a bit hard to get... @DukeAndrey, I can sympathize fully.

Hmm I recall seeing some vid from Siggraph 2005 where they showed a movie.. Is this similar? Hmm is this about a sequence of images?

But oh what that person would be missing out on if they skipped this post! (I almost did, then I remembered I'm obsessed :D ) Anyhow, the length of time that the project has been going on has totally sweetened the deal. I've got a machine that can handle these images, and maybe I could make an animated movie where the maps blend from one month to the next! How sweet would THAT be!? It's definately not something I could have done when this project started since there was only one "month" to choose from. Thanks, Blender Nation!

Every program that I use crashes when I try to load such a HUMONGO image. Blender, IE, Opera, GIMP, Preview, all crash in a matter of seconds. Great post, but one little problem.
