Angkor Wat

January 20, 2006
This SAR image centers over Angkor Wat, a temple complex in Angkor, Cambodia, built by the Khmer people during the 9th century and later abandoned in the 15th century. It is the best preserved example of Khmer architecture, lying less than a mile to the south of the royal city. The words Angkor and Wat mean City Temple. The temple was originally devoted to the worship of Brahma, but in later years to that of Buddha. Sandstone of various colors was the principal material used by the Khmers, however, limonite was also used. The stone was cut into huge blocks which were constructed to fit together with great accuracy without the use of cement. Angkor Wat was placed on the World Heritage List in 1992. The rectangular blue strip evident in the image is a reservoir belonging to the complex. To the right of the rectangle is the outline of a smaller blue square, which is another reservoir surrounding the temple. This SAR interferogram was created by processing two SAR images acquired by the ERS satellites in 1997. The type of processing used produces an Interferomeric Land Use image, in which different colors show different land use: green generally corresponds to heavily vegetated areas (forests), blue to water surfaces, red to rocky terrains and fields and yellow to urban areas.
