We are carrying out a comprehensive multi-wavelength study of dwarf galaxies in the Local Volume (< 5 Mpc). After our all-sky survey more than doubled the dwarf census we are now measuring structural parameters, integrated properties, and velocities. Our 200-orbit HST snapshot program yields stellar content, star formation history, and TRGB distances. We can thus study the morphology-density relation in galaxy groups in three dimensions, the influence of environment on galaxy evolution, and the universality of the metallicity-surface brightness-luminosity relation.
