We present deep, multicolor CCD photometry for a sample of over 300 field spiral galaxies with V0 < 3000 km/sec. These data are combined with rotational velocities derived from 21-cm line-widths and redshift-independent distances are measured using the luminosity--line-width relation. The velocity field within this region is examined and individual peculiar velocities are computed by subtracting a uniform Hubble expansion field. The relatively dense sampling afforded by these data reveals systematic peculiar motions associated with the non-uniform distribution of matter, particularly with the region within a distance of 10 Mpc. We also find larger-scale systematic flows and characterize these using a simple analytic model. The prospects for a more detailed analysis are briefly discussed.
