I tried using some of the more exotic camera types for earth surface
renders and came up with this.  It is a view from above onto the surface
using a fisheye camera (viewing angle just above 180 deg. so the sky is
well visible.

Location is 36.5 deg. north, 111.8 deg. west - you can see the Grand
Canyon on the lower left and Lake Powell on the upper right.  The image
looks probably better when rotated 90 deg. to the right but i wanted to
keep the north=up orientation.

That look fantastic.

Have you done the fly-through of the Grand Canyon on Google Earth?

Fantastic work. Is it just me or does the landscape look inverted? Or s 
this an effect created by the camera? For example the river in the lower 
right looks to be raised up and casts long shadows on the landscape.

Last time i checked Google Earth was a Windows-only program...

Short answer: it is just you. ;-)

Long answer: we are quite used to the light coming from the upper left 
in such images - therefore satellite images from the northern hemisphere 
  commonly appear inverted.  You can either try to get used to it and 
mentally 'reinvert' it or simply rotate the image 90 deg. to the right 
as i suggested.

Wow. Now it is for MacOS X too. That doesn't alter the root issue...

I haven't been to Lake Powell in years.  So THAT'S what it looks like from
above.

Is the "air glow" part of the satellite image?  Or did you add that?

Ken

You mean the bright sky near the sun direction?  That's scattering media.
