Hi, FYI I have half-written a new module called d.barb for GRASS,
it does like the above (GRIB data; partial code reused from
d.rast.arrow) but also allows an option for sparse lagrangian
style at vector points using DB attributes for velo,dir, & an
option to use magnitude-sticks of varying length instead of
barbs.

The technology is well in hand, as always I just need to find
some free time to clean it up.


for now, you might try the zyGrib software.
