  We present the first results of a study where we determine the metallicity
distribution function in the Galactic disks as a function of height above the
Galactic plane. Observations in the Stromgren photometric system enables us to
identify the dwarf stars and derive metallicities for them. The resulting
metallicity distribution functions at 0.5 and 2.0 kpc above the Galactic plane
are significantly broader and more metal-rich than is anticipated from standard
models such as the Besancon model. Our results can be explained by invoking a
smaller scale height and larger local normalisation for the thick disk than is
commonly used in the models. These results are compatible with recent
determinations of the thick disk scale height based e.g. on SDSS data.
  The age of the stellar populations as a function of height above the Galactic
plane is also investigated by studying the turn-off colour and metallicity. We
tentatively find that at 2.0 kpc above the Galactic plane there exist an
intermediate age population.
