  Projected in the sky, galaxies are spatially-resolved objects. To understand
how they formed and evolve it is necessary to study the spatial distribution of
their observables. In this review talk, we briefly describe some scaling
relations used to understand the physical processes that drive galaxy
evolution, in particular for disk-like star-forming galaxies. First, we explore
the relations derived using integrated galactic properties, then we introduce
the scaling relations at kpc scales derived using the technique called Integral
Field Spectroscopy (IFS) for large samples of galaxies in the nearby
Universe.The very existence of scaling relations at kpc scales is a strong
evidence that any physical scenario that explains the observed global scaling
relations must be able to also explain their local counterpart.
