IRIS Videoglobe Imagery - Making Spherical Images with ImageMagick

How to wrap these realtime earthquake maps into spheres for animation.

To make a series of images of today.jpg, suitable for animation, try this: First roll the today image, wrapping left edge of rectangle around onto right, like:

   convert -roll +0+0   today.jpg today.rolled0.jpg 
   convert -roll +50+0  today.jpg today.rolled50.jpg 
   convert -roll +100+0 today.jpg today.rolled100.jpg 
   convert -roll +150+0 today.jpg today.rolled150.jpg 
   etc. 

   The roll amounts are pixels, not degrees!

   Then use Fred Weinhaus' spherize script (according to his usage req's), like:

   spherize.sh  -b none -s  today.rolled0.jpg   today.rolled0.sphere.jpg   
   spherize.sh  -b none -s  today.rolled50.jpg  today.rolled50.sphere.jpg   
   spherize.sh  -b none -s  today.rolled100.jpg today.rolled100.sphere.jpg   
   spherize.sh  -b none -s  today.rolled150.jpg today.rolled150.sphere.jpg   
   etc.

You can make images like these:
