Supernova remnants commonly display strong internal inhomogeneities in physical properties; however, most of the observational studies found in the literature are limited to integrated data for extragalactic objects or data from very specific parts of the galactic objects. Thus, important information may be lost. We studied the spatial variation of the electron density and the kinematics of N49, the brightest supernova remnant in the Large Magellanic Cloud, based on spatial resolve observations sampling the whole object.
