Hi there,

Pat has some great maps there and I really found them useful, however I recently found some maps from NASA's Blue MArble Project and I must say, they're INCREDIBLE! The resolution even comes down to 1km per pixel! Anyways, those are some of the basemaps that I'm using now so if anyone wants the links, check it out

You'll want to find the download page and download the maps some are bigger than 32mb tho. Took me about 20 minutes to import it into DA with a subsynoptic zoom.

Just out of curiosity, which blue marble did you import? 20 minutes seems a very long time..and I doubt we are dealing with the full resolution map in said 20 minutes....43200X21600 pixels is a bit much for most pcs to handle, to say nothing about seaming the two hemispheres together to make the whole map!

I think a great deal of the work America's NASA did myself regarding the Blue Marble Project...I've mentioned the work a couple of times on this very forum. Although others have produced higher quality maps based on the imagery than NASA.

Glad you found my maps useful!


For those interested in a direct download link to the Blue Marble imagery mentioned above, here is the link:

Hi, sorry for the late reply. I don't remember which one I imported but I can assure you it was over 128 MB! I only have 756 MB of RAM so I was quite surprised myself!

I didn't expect a reply to be honest. Anyway, you didn't import the full resolution map! The half resolution map uses ~670 mbs of RAM (the 173.5 mb download), and there are import issues with maps above 20,000 pixels.

So I still have no idea what you imported from NASA!

In any event, I don't care.
