[aspect-devel] Localizing processes on spherical shell models

Internally, everything in ASPECT works in an x-y-z coordinate system. This is, 
of course, not very convenient if you try to match external lat-long-depth 
data to the ASPECT coordinate system. But there are functions in ASPECT that 
allow you to convert between coordinate systems. I think you should take a 
look at the GPlates plugin, for example, to see how it's done there. In 
general, take a look at plugins that do something similar to what you want to 
do (as well as, of course, the existing cookbooks).
