  This paper is the first paper of a series that will present the derivation of
the modal mineralogy of Mars (M3 project) at a global scale from the
near-infrared dataset acquired by the imaging spectrometer OMEGA (Observatoire
pour la Min\'eralogie, l'Eau, les Glaces et l'Activit\'e) on board ESA/Mars
Express. The objective is to create and provide a global 3-D image-cube of Mars
at 32px/{\deg} covering most of Mars surface. This product has several
advantages. First, it can be used to instantaneously extract atmospheric- and
aerosol-corrected near-infrared (NIR) spectra from any location on Mars.
Second, several new data maps can be built as discussed here. That includes new
global mineral distributions, quantitative mineral abundance distributions and
maps of Martian surface chemistry (wt % oxide) detailed in a companion paper
(Riu et al., submitted). Here we present the method to derive the global
hyperspectral cube from several hundred millions of spectra. Global maps of
some mafic minerals are then shown, and compared to previous works.
