You can use r.mapcalc. If mymap is your raster layer and you want to
change the raster cell at coordinates 52deg and 10deg, use
r.mapcalc "mymap = if(x()==52.0 && y()==10.00, 1, mymap)" --replace

Hi,
is there a simple way to set the value of a specific raster cell (e.g.
defined by the coordinate of its cell center). One way could be to
define a point by the coordinates (e.g. v.in.ascii) and then to
convert the point to raster (v.to.rast) and use the mapcalculator to
modify the original raster with the help of this new-point raster...
...But is there a simpler way to "call" the raster-cell directly?
