| I will present several state-of-the-art panoramic surveys of the outskirts of nearby spiral galaxies (in particular M31, M33, M81, NGC891 and NGC2683). These new photometric and kinematic data are giving us a uniquely detailed view of the structure and dynamics of the closest giant disk galaxies to the Milky Way. We are now able to study the large scale trends of galactic components and detect a plethora of small sub-structures. I will discuss the consequences of these findings for our understanding of the formation of thick disks and stellar halos. |
