I'd like to create vector lines from vector or raster point data. I have rasters of x and y wind components and have used r.mapcalc to compute the x and y values of the original raster grid points and the x and y values for displacements points due to the wind speed and direction. I'd like to take these x and y location values in these rasters and create vector lines that connect the original x,y grid points to the displacement points. I can create vector points with these values at the gird points using r.to.vect, but not sure how to create new vector lines with the info.
Thanks, Lee
