  The SKA will be a state of the art radiotelescope optimized for both large
area surveys as well as for deep pointed observations. In this paper we analyze
the impact that the SKA will have on Galactic studies, starting from the
immense legacy value of the all-sky survey proposed by the continuum SWG but
also presenting some areas of Galactic Science that particularly benefit from
SKA observations both surveys and pointed. The planned all-sky survey will be
characterized by unique spatial resolution, sensitivity and survey speed,
providing us with a wide-field atlas of the Galactic continuum emission.
Synergies with existing, current and planned radio Galactic Plane surveys will
be discussed. SKA will give the opportunity to create a sensitive catalog of
discrete Galactic radio sources, most of them representing the interaction of
stars at various stages of their evolution with the environment: complete
census of all stage of HII regions evolution; complete census of late stages of
stellar evolution such as PNe and SNRs; detection of stellar winds, thermal
jets, Symbiotic systems, Chemically Peculiar and dMe stars, active binary
systems in both flaring and quiescent states. Coherent emission events like
Cyclotron Maser in the magnetospheres of different classes of stars can be
detected. Pointed, deep observations will allow new insights into the physics
of the coronae and plasma processes in active stellar systems and single stars,
enabling the detection of flaring activity in larger stellar population for a
better comprehension of the mechanism of energy release in the atmospheres of
stars with different masses and age.
