Earth as Art
bravehamster writes "There's a new exhibit at the Library of Congress displaying images taken of earth by the Landsat satellites. The exhibit displays satellite photos that have an intrinsic aesthetic quality, showing the beauty of Earth as seen from really far away. There's an article about it on MSNBC here, and don't forget to check out those fjords!"
Neat pictures, but the screen saver is 16bit and doesn't run on the systems noted. I hope someone updates this.
It's really nice that they are providing poster size prints for download...r eenland_hires.jpg k patok_hires.jpg (I wonder what the red stuff in this one is?)r aq_hires.jpg
Most other places would give you a small thumbnail and ask you to pay for the full size version.
These one's are pretty cool:

Don't forget the exhibition Earth from above by Yann Arthus-Bertrand! Yes, I admit it's in another league - the photos in EFA are taken from planes, but there are some really nice gems in there.
You have reached this page because your web browser is not equipped to view the Earth from Above website.
To enjoy the 'Earth from Above on the web' you will need to download the latest versions of:
Netscape 4+ or Internet Explorer 4+
(NOTE: Netscape 6 is not supported)
IE 4??? Netscape 6 isn't supported?
I would bet a few dollars that a current mozilla release (or opera, konqueror, galeon, pheonix, etc. etc.) just might be a little bit more functional than IE 4.
you can get something like this in print for free

As for the red stuff, I think I came across one photo with red that indicated vegetation of sort. But I doubt that colors always mean the same thing.
The article makes note that some colors [are] "assigned arbitrarily to represent data -- such as levels of heat -- not visible to the human eye."
Earth From The Air
It is the same photograhper but the exhibition is on in London. I highly recommend it. The photos are absolutly mind blowing. The prints are about 12ft x 6ft.

Perhaps you need historical ones? ;-)
Greenland is governed by Denmark which makes it part of Europe.

The colours are artificial. Landsat doesn't take photographs.
This contains load of images taken by the space shuttle. Well worth a look... Earth From Space
The bavarian TV station BR is broadcasting a similiar programme on a nightly basis. They call ist "Space-Night". Hours of beautiful earth views with a funky soundtrack. Since they are doing this, I always go to bed with the TV running. You can order the DVDs at the online shop. German only. You'll have to ask the fish.

Whoa!! Your crazy way of thinking seems so new and revolutionary to me.
Seriously, though, fjords can be approximated by fractals. To show this, all one needs to do is implement a fractal box counting algorithm to the image in question. Fractal box counting will show that the fjords have a boundary that is approximately 1.4 dimensions (rather than the typical 1-dimensional boundary of a circle or square) and thus, can not be measured with a finite 1-dimensional measure such as length. Thus the coastline length can be approximated by infinity. Everybody knows that anything remotely close to infinity is still infinity (e.g. \infty - 1,000,000,000 is still infinity), thus the coastline is infinitely long, at least in 1-D.
This message is a queue for all of the Dynamical Systems Mathematicians to step in and correct me (although I think I am correct).

The colors are not 'artificial'. Landsat 7 takes data in 7 wavebands of light, only 3 of which are the red, blue, green we can see with human vision. In the Parana River scene, we used band 4 for green. That's our 'vegetation' band, and anything with chlorophyll shows up very bright in that band, thus looking very green in that image.
So the colors are not artificial, they're just using frequencies of light that you normally can't see.
