This pair of multitemporal radar
images, using the Synthetic Aperture Radar (SAR) onboard the ERS-1 satellite and
the Advanced Synthetic Aperture Radar (ASAR) onboard Envisat show Rome and the Latium
province surrounding it. The 1993 SAR multitemporal image at right was created from
three acquisitions, in January 1992, April 1993, and June 1993, whereas the 2003
ASAR image, at left, was created acquistions made in November 2002, August 2003,

This Advanced Synthetic Aperture
Radar (ASAR) multitemporal colour composite image shows an area of 100 Km swath width
over the city of Rome, Italy (large bright area centre left) and most of southern
part of the Lazio region. Towards the southeast of Rome the Ciampino International
Airport and the volcanic lakes (Albano and Nemi) of the Albani Hills are visible.
In the upper right corner of the image is the Fucino Basin. The image is made of
three ASAR images acquired on different dates and assigning a colour ( RGB )
to each date ( Red : 10 November 2002, Green : 17 August 2003, Blue
: 4 May 2003). |
