The evolution of the properties of galaxies as a function of redshift provides a sensitive probe of the theories of galaxy formation and evolution. At faint magnitudes the standard approach has been to measure these properties (luminosity, color and clustering) as a function of limiting magnitude. Due to the broad width of the redshift distribution, at faint magnitudes, it becomes progressively harder to interpret any evolutionary signal. If, however, we utilize multicolor information to derive photometric-redshifts we can define narrow intervals in redshift over which to measure the statistical nature of the galaxies. In a series of pilot studies we have demonstrated that we can measure the luminosity function, spectral type and clustering of galaxies as a function of photometric-redshift. The limitation with our current data is that we cover only a small (and possibly biased) volume of the Universe. We, therefore, request time to apply these techniques to a statistically fair sample to provide the first definitive measure of galaxy evolution (principally the evolution of the luminosity function, clustering and distribution of galaxy spectral types as a function of photometric-redshift). This proposal represents the completion of a multicolor survey we started in the last semester.
