[R-sig-Geo] flow visualization in lat/lon space

[Thomas Adams]

Markus,

It's *possible* something like the Grid Analysis and Display System 
(GrADS) (http://www.iges.org/grads/) could do the trick if you tweaked 
the data right — but that may be too much of a chore. Look at the image 
here http://www.iges.org/grads/gadoc/tutorial.html down the page a bit.

Regards,
Tom
