  GAIA data will create a precise 3-dimensional map of the Galaxy, providing
positional information, radial velocities, luminosity, temperature and chemical
composition of a representative sample of stars. Here we present a new
implementation of the Padova Galaxy Model, where kinematics simulations are
included. A few examples of application to GAIA science are discussed, in
particular concerning radial velocities determinations of the thin and thick
disk.
