  We present a wide-field, high spatial and velocity resolution map of the
entire extended HI distribution of the nearby Local Group dwarf galaxy NGC
6822. The observations were obtained with the Parkes single-dish telescope and
the Australia Telescope Compact Array in mosaicing mode. NGC 6822 has an
extended HI-disk which is shaped by the presence of numerous HI holes and
shells, including a supergiant shell, and the effects of tidal interaction, in
the form of a tidal arm and an infalling or interacting HI complex. These tidal
features are not obvious in lower resolution data, and only the proximity of
NGC 6822 enables us to see them clearly. This suggests that the importance of
minor interactions in dwarf galaxies may be larger than previously assumed.
