[GRASS-user] linking point attribute to raster layer

[Leedal, David]

I would like to achieve the following situation:
set up a set of vector point objects and attribute table; define a raster layer (in this case with values between 0 and 1); have a  value in each vector point's attribute table that is dynamically determined by the pixel it is contained by in the raster overlay.
Any pointers as to where to begin??
kind regards
David
