Abstract

In 1978 NASA launched SEASAT which flew its first fine-resolution synoptic spaceborne SAR. The short-lived mission of just 100 days collected valuable data that spanned many disciplines. To date only 15% of this data was processed digitally, as is needed for quantitative assessment, and the data set has been largely unavailable for over 20 years. The objective of this joint effort is to restore and digitally process the entire SEASAT SAR data set for the first time, providing an invaluable opportunity to extend contemporary systematic measurements of surface change to an earlier time period, facilitating retrospective research with spaceborne SAR imagery.

The presentation will give a short history of the SEASAT L-band mission and overview of the restoration project. This collaborative effort will process, catalog, distribute, and demonstrate the scientific value of the SEASAT SAR data. Recent digitally processed examples will be presented from a variety of disciplines.
