The study of radial stellar population gradients is an incredibly useful tool for understanding the formation of galaxies, constraining accretion, mergers, and radial migration. These gradients are now typically derived via integral-field unit (IFU) spectroscopy, an innovation which revolutionised the field of ground-based galaxy surveys. Whilst some of these surveys focus on a small number of objects, observed in exquisite detail with a single IFU (e.g. CALIFA, ATLAS3D), others use multi-IFU capabilities to obtain much larger samples, albeit with a reduced spatial coverage (e.g. MaNGA, Hector). In this talk, I will discuss the unique challenges presented by these latter compact IFU surveys, including the effects of atmospheric seeing on the recovery of spatially-resolved properties. I will also present results using the radial stellar population gradients of galaxies drawn from the SAMI Galaxy Survey, including their variation across morphological types and environment.
