Abstract: Gaia is an ESA mission expected to chart a three-dimensional map of our Milky Way galaxy, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will also observe nearby galaxies resolved in stars. The main goal of our project is to obtain the spatial distribution of different stellar components in these galaxies. The Magellanic Clouds, being the nearest neighbours of our Galaxy, are the most important targets with a large number of observed stars. In order to obtain their spatial distribution already existing catalogues are used, which are homogeneous, have a good coverage of the galaxies, and are deep enough, such as The Magellanic Clouds Photometric Survey, 2MASS, SuperCosmos Sky Survey, etc. The spatial distribution of different Magellanic Clouds’ populations is studied using isopleth maps and radial density profiles. Preliminary results are now available. Exponential disk and King profiles seem to fit the spatial distribution of the various stellar populations very well.
