If you have photoshop 7 or CS its quite easy to do. I made one here.. scroll down to page bottom.

It is done like this:
Your image is 2:1 for example: 1600 px wide and 800 px high.
Next open your image in Photoshop
Invert the image so that the ground is at the top of the image. Means the image is upside down
then FILTER | DISTORT | POLAR Coordinates
This will convert your rectangle image to a circle.
The ground will become the sphere.. and the sky will wrap all around the sphere.
THEN if the new transformed image is a bit elongated
Duplicate Background layer
EDIT | FREE TRANSFORM | and drag the right side of the image until it becomes a perfect circle.
Then delete the background and Flatten the image and save as your file format.
Do I have a name for it? No but I am sure someone has already.
Hope this helps
