For immediate release: November 10, 2003 MDA Measuring Land Motion within Millimetres Using RADARSAT-1 ImageryMacDonald, Dettwiler and Associates Ltd. (TSX: MDA) is delivering information to create products that measure land motion - within millimeters - using RADARSAT-1 data. The information is used to reveal areas prone to land slippage, flooding, subsidence, and volcano or earthquake activity.These products are being delivered to a customer in Italy. The process that makes such remarkable levels of accuracy possible is based on "Interferometric Synthetic Aperture Radar", or InSAR. RADARSAT-1 is the only commercial satellite that can collect data suitable for InSAR applications. Over 2,000 RADARSAT-1 images are being collected over Italy to create an InSAR database of the entire country. The final product can then be used to perform such diverse tasks as monitoring land subsidence in areas of oil extraction, or evaluating the smallest structural movement of buildings and bridges.
