We have computed a global mosaic of all the VIMS data of Titan acquired between July 2004 (T0) and June 2010 (T70) in 256 spectral channels from 0.88 to 5.10 μm, at a resolution of 32 pixels per degree (corresponding to 1.3 km/pixel at the equator). Data have been sorted to use low resolution cubes as background and high resolution cubes ontop of the mosaic. To mitigate the blurring effect of the atmosphere, a series of filters has been created so as to include in the mosaic only the pixels acquired with emission and incidence angles lower than 80°, a phase angle lower than 100°, an airmass (defined by 1/cos i + 1/cos e) lower than 7, and with an exposure time in the range 40-240 ms to avoid both too noisy cubes and saturation effects at short wavelengths. The data were first calibrated to I/F. The illumination geometry has then been normalized by dividing the calibrated data by the cosine of the incidence angle.
