I have used r.random to generate some UTM points from my raster as well
as make a sites file of some UTM points of interest. I am interested in
the corresponding value associated with the UTM location(raster cell) and
I am having to use d.what.rast to click on the marker on the raster map
to see the value. Is there a better way to determine the attribute value of the
UTM cordinates rather that using d.what.rast. Maybe input the UTM or LL
cordinate and the output will be the corresponding raster value.
Thank you

yes, you might try s.rand/s.sample, from
ftp://pasture.ecn.purdue.edu/pub/mccauley/grass
s.rand is used to create random points.
s.sample will take a sites file as input and
sample a raster map at each site.
Thank you
