The information gained from spatially resolved optical spectroscopy has proven crucial to understanding the complete picture of galaxies and their contents. In order to fully understand the interplay between the processes that govern and regulate star formation and galaxy evolution we are building building a sample of the largest, highest spatial resolution, and widest spectral coverage data cubes ever taken for nearby galaxies: the Las Campanas PrISM Survey.
I will present recent results and ongoing work using our data cubes to map the ionized ISM and its properties at spatial scales of order 10 pc in nearby galaxies such as M83. The high spatial resolution of our data affords us the opportunity to study the characteristics and total contribution of diffuse ionized gas, a less well-understood component of nearby galaxies, as well as metallicties, star formation rates gas kinematics and more. I will also discuss how resolved spectroscopy can help detect, quantify and distinguish between star formation, shocks, diffuse ionized gas and AGN to help better inform larger, less resolved studies of galaxy properties.
