They are aerial photos of places in the real Miami, which the producers
drop into the show (usually as a new scene begins) to help create the illusion
that the show is filmed in Miami.
Although
quite a few of the scenes in the early first season were actually shot
in Miami, most of the show (since the 6th episode) has been filmed in Southern
California. And after the first season, they gave up on Miami entirely,
and moved all production to L.A. But they still use these aerial "establishing
shots" to help set the Miami mood.
Below
is a list of many of these establishing shots, listed in the order in which
they appear on the Episode Index page, with
descriptions of what the camera is showing us in these scenes, and links
to Live Local aerial photo-maps
of the actual locations.
