Fortunately, the new generation of deep, wide-area (> 1 square degree) extragalactic surveys — designed to study the evolution of galaxies over a wide range in environ- ment — can complement MCAO facilities by both containing suitable asterisms and hav- ing the multi-wavelength coverage needed to obtain photometric redshifts and star for- mation rates for the galaxies in the field. The Spitzer Extragalactic Representative Volume Survey (SERVS; Mauduit et al., 2012) and as- sociated VISTA Deep Extragalactic Observa- tions (VIDEO) survey (Jarvis et al., 2013) pro- vide 12 square degrees of deep near-infrared observations in seven bands from 0.9-4.5 mi- crons (μm), enough area to fin
