In the next decade our understanding of the Milky Way's dynamics, stellar populations, and structure will be revolutionized, thanks to proposed astrometric, spectroscopic and photometric surveys. We describe the new science this multidimensional view will enable across astrophysics, from constraints on dark matter to insights into galaxy formation.
