We built an optimal basis of low resolution templates for galaxies in the wavelength range of 0.2 to 10 microns using a variation of the algorithm presented by Budavari et al. (2000). We used eleven bands of photometry for about 17000 galaxies in the NDWFS Bootes field with spectroscopic redshifts measured by the AGN and Galaxy Evolution Survey. We also developed algorithms to accurately determine photometric redshifts, K corrections and bolometric Luminosities using these optimal spectral templates basis. Our photometric redshifts estimates have an accuracy of dz=0.04(1+z) for the 95% clipped distribution. Finally, we also used this algorithms to study the spectral type distribution of the field and estimate luminosity functions of galaxies as a function of redshift and spectral type.
