This proposal is aimed on obtaining legacy-level observational datasets on the Milky Way Galactic disk. The ultimate goal of the entire project is to have model independent and systematics free measurements of the fluxes in nuclear lines (511 keV annihilation emission 1.8 MeV Al26 and 1.17 MeV and 1.33 MeV Fe60 lines) and a broad band spectrum of the Galactic background emission which at different energies is provided either by cumulative emission of faint Galactic sources or by interaction of low energy cosmic rays with interstellar medium. Taking into account the unique combination of properties of the INTEGRAL instruments - broad band coverage large fields of view and possibilities to eliminate the contribution of discrete sources from the total measured photon flux the proposed strategy is the best possible usage of the valuable INTEGRAL time. Wide mapping of the Milky Way during the campaign of Galactic latitude scans also contributes to the legacy of the INTEGRAL observatory giving the opportunity to study the population of Galactic sources at high latitudes.
