  The detection of radial and non-radial solar-like oscillations in thousands
of G-K giants with CoRoT and Kepler is paving the road for detailed studies of
stellar populations in the Galaxy. The available average seismic constraints
allow a precise and largely model-independent determination of stellar radii
(hence distances) and masses. We here briefly report on the distance
determination of thousands of giants in the CoRoT and Kepler fields of view.
