The Visible InfraRed (VIR) mapping spectrometer onboard Dawn mission has obtained the spatial distribution of the spectral reflectance of Vesta in the wavelength ranges between 0.25-1.07 micrometers and 0.95-5.1 micrometers. A photometric correction allows to characterize the intrinsic variability of the surface albedo by removing the dependance of the reflectance from the observing geometry. In this work, we present the photometric correction obtained for observations from the Survey, HAMO and HAMO 2 mission phases at Vesta in the whole spectral range investigated by VIR, as well as the surface albedo maps.
