right; i.e. either with:

  r.shaded.relief + d.shadedmap for two raster maps
    (e.g. DEM and satellite image), or opacity overlay in GUIs
or
  r.shaded.relief + multiple d.vect overlays (shapefiles)
    using opacity slider in the GUIs. (or convert vector maps
    to raster with v.to.rast then with d.shadedmap as above.
or
  nviz elevation=dem color=satellite_image


you can use r.in.wms or more simply the r.in.onearth module
from wiki addons to pull in e.g. LANDSAT imagery from NASA.


some of the examples here give command scripts:
