We describe the progress of a large optical and near-infrared imaging study of a complete sample of 57 spiral galaxies. We have obtained B, I, K' and Hα imaging to map stellar populations and massive star formation (SF) across the arm and interarm regions, in order to study the distribution of mass and SF in these different and distinct environments. We briefly describe the background to our program, the sample selection, observations, and the reduction procedures. We present a K' image and preliminary radial profiles of the SABcd (SXT6) galaxy NGC 1042. SF appears to induce differences between the arm and interarm profiles, and to enlarge the scale length of the exponential disk of the galaxy.
