Exploring the New Era of Wide-Field High Spatial Resolution Integral Spectroscopy of Nearby Galaxies // I will provide an overview of the Las Campanas Observatory Typhoon Survey which uses the Progressive Integral Step Method (PrISM) to construct wide-field optical spectral data cubes of nearby galaxies. This method achieves spatial resolution between 6 and 100 pc which is an order of magnitude higher than most current IFS surveys. I will discuss how this resolution has allowed exploration of the azimuthal variation of metallicity in disk galaxies and informs the effects of diffuse ionized gas on radial metallicity gradients as well as starburst-AGN mixing. Finally, I will present the upcoming SDSS-V Local Volume Mapper which takes the wide-field high spatial resolution IFS survey concept to an extreme and exciting new level.
