The history of sea islands in the Altamaha River delta on the coast of Georgia can be seen in this image. The outlines of long-lost plantation rice fields, canals, dikes and other inlets are clearly defined. Salt marshes are shown in red, while dense cypress and live oak tree canopies are seen in yellow-greens. Image taken by the Airborne Synthetic Aperture Radar (AIRSAR) on March 9, 2001.
