Alexander,
thanks for your script. Out of the office for the entire week, I'll give
it a try a bit later.
My solution was based on a spatialite export of the vector map, then
some sql fiddling with vertices coordinates, and finally re-import
corrdinates and angles as a point vector. As Hamish
Hi grass users;
We traced bird migration by marine radar.
By using graphic analyze of radar monitor capture on PC, we had many line
vectors of bird flight.
I would like to add new columns of the number of node and lenght of line vector,
So;
v.db.addcol line_db columns=num_node int

Hi, all -
I'm TRYING to classify an aerial image via feature extraction.
Problem is, I'm new to grass and can't figure out how to import an image!
I'm doing this via the gui (layer manager) - no time to play with code. :(
I have a projected tif w/ a tfw. It has three bands.

Yasuo -
For length:
v.to.db map=line_db option=length units=k column=length
This would put the length of the line into the column, in kilometers. If
you want some other unit, check v.to.db --help to choose the right
parameter.
Thank you for useful adivece!

Just one question (to more experienced users of this tool): Which is the
best method to use for products such as LAI, NDVI of fPAR? Neares neighbor
or cubic? Thanks

Hi Helena
I'm probably not what we can call an experienced users but the combo :
resampling to higher resolution (g.region) + nearest neighbourgh (r.proj)
+ r.resamp.stats to match the default res works great for me

So the import with the corrected raster is ok, i.e. is of global (-180
to 180 E, -60 to 90 N) extent?

Yes, everything works great. Thanks again.
Ok, good to know. Yeah, the algorithm could be improved I guess. But,
the improvement that I would suggest is supposed to be the -l flag,
right? Just force it to be 180W and 180E... I thought (the -l flag) it
is just a recent addition to GRASS 6.4,
