Scientific paper

We explore the motivation behind large stellar surveys in Galactic astronomy, in particular, surveys that measure the photometric, phase space and abundance properties of thousands or millions of stars. These observations are essential to unravelling the sequence of events involved in galaxy formation and evolution, although disentangling key signatures from the complexity continues to be very challenging. The new data will require major advances in our understanding of stellar atmospheres, stellar chemistry, the dynamics of the Galaxy and the Local Group.
