Abstract
Research on two-dimensional (2-D) properties of galaxies is a significant component of the study of galaxy formation and evolution. Through the spatial distribution of physical properties (derived from integrated luminosity and spectroscopy) of galaxies, we are allowed to realize the inner environment and evolution history of each individual galaxy and finally answer how galaxies were assembled. In this paper, with reviewing previous work, we present a proposal for study on 2-D properties of nearby galaxies. In our prospective work, we will make use of multi-wavelength data covering a range from ultraviolet to far-infrared to determine the distributions of properties such as age, metallicity and dust-reddening in nearby galaxies, and try to remove the degeneracy among them. Combining with surface photometry and spectroscopy, we will also analyze the distribution of HII regions and star formation properties in galaxies. In our future plan, the World Space Observatory for Ultraviolet (WSO/UV) will be applied to our research and allow detail diagnosis of nearby galaxies at ultraviolet band.
