[GRASS5] v.to.rastdir

[Helena Mitasova]

Brad,

when you are at it, would you be also able to try out v.to.rast with an 
option to compute the
direction of the lines (e.g. streams)?

It is in
http://skagit.meas.ncsu.edu/~helena/grasswork/grasscontrib/
v.to.rastdir.tar

Jaro has already updated it to GRASS6, so it just needs to be merged 
with any
changes that might have been done since april and try it out. It should 
convert
lines to a raster with cell values representing the aspect (or angle 
measured from north, I believe).
So for streams that are digitized downstream the angle would represent 
flow direction.
There are many applications for this, among them the angle can be used 
in r.sim.water and probably
also in r.flow to prescribe flow direction.

Thank you,

Helena

I updated r.carve to GRASS6 and it seems to work rather well.

Is it okay if I add it to CVS?
