The star formation process shapes galaxies with time and understanding what affects his efficiency as well as our ability to characterize it in details is of great importance in Astronomy. Star-forming regions present a large variety of sizes and shapes and their unquestionable beauty has made them targets of choice for imagers. With observations on nearby galaxies using the CFHT’s imaging Fourrier transform spectrograph SITELLE, we have now access to high-spatial resolution hyperspectral datacube that covers a large field of view (11'x11'), and that provides a tremendous amount of information on the HII regions that populates the various galactic environments (size, gas density, ionization parameter, metallicity, etc). The nature of the young massive stars responsible for the ionization of the gas and the physical conditions in the surrounding interstellar medium are characteristics that we are particularly interested in. In this presentation, I will show the progress made on the determination of these physical quantities and emphasize on the need to have a statistically significant sample to pursue our ultimate goal to understand the impact of galactic environments on star-formation.
