We present a proper motion survey over about 200 square degrees towards the NGP, based on the material used for the construction of the GSC-II, that we are using to study the vertical structure and kinematics of the Galaxy. In particular, we measured the rotation velocity of the halo up to 10 kpc above the galactic plane traced by a sample of RR Lyræ and BHB giants for which radial velocities were used to recover the complete distribution of the spatial velocities. Finally, the impact of astrometric and spectroscopic GAIA observation are discussed.
