The moduli space of flat surfaces is stratified according to the number and multiplicities of zeros. The goal of the talk is to construct a compactification of those strata that is as nice as Deligne-Mumford's compactification of the moduli space of curves. Applications include computation of characteristic quantities of flat surfaces.
