Abstract: The S-PLUS survey, with its unique combinations of 7 narrow + 5 broad band filters, allows one to (among many other things!) map stellar populations and nebular emission in nearby galaxies. This in turn allows one to mimick the kind of work done with integral-field-spectroscopy surveys like CALIFA and MaNGA over the past 10 years, but with advantages in terms of angular coverage (much wider than traditional IFUs). The obvious disadvantage is its limited spectral resolution, but simulations and empirical tests show that S-PLUS photometry, processed through our photo-spectral synthesis tools, allows one to recover stellar and emission line properties with remarkable precision.

The SCUBES project aims to: (1) offer tools to extract 12-bands datacubes from the S-PLUS server and an open database of datacubes for nearby galaxies; (2) explore these data to obtain both 2D maps and radial profiles of properties like mean stellar age, surface stellar mass density, dust extinction, emission line fluxes and equivalent widths. This talk reports on the current status of the project, the difficulties faced and strategies to overcome them, as well as some initial astrophysical results.
