SAR Orbit number: 51858
31 March 2005
This multitemporal radar image of the west coast of Italy
combines data from three SAR radar acquisitions made by ERS-2.
Readily visible is the mountainous formation of Circeo,
the location according to Homeric tradition of the temple of the sorceress Circe,
mid-image, just south of a series of salt-water coastal lakes which today are
the Italian National Park San Felice Circeo. Farther south along the
Gulf of Gaeta lie three
spectacular sites, Terracina, Sperlonga, and Gaeta; Terracina in particular
is the location of ruins of a major Greek temple
of antiquity. Gaeta is situated on a promontory at the tip of the peninsula just
north of the curving blue bay at mid-right; Terracina on a hilltop and along the
shallow bay southwest of the lake of Fondi which is slightly inland, Sperlonga on
the coast between the two cities.
The volcanic islands of Ventotene and Ponza (the largest, which has
served as a place of exile throughout Italian history) can be
seen at the extreme lower left.
The impression that the mountains "lean" toward the radar
is an effect characteristic of side-looking
radars in an ascending pass, where returns from one side of the slope
reach the radar before those from the other side.
This multitemporal image was created by combining acquisitions from
21 March 2005 (red), 1 May 2000 (green), and 17 July 1995 (blue).
