The image above shows a comparison of the Chesapeake Bay as derived from the Landsat 7 satellite (shown in green and tan) and made by Captain John Smith, when he explored this impressive estuary for three months in 1608. Smith's careful surveying resulted in a map that compares remarkably well with the rectified Landsat image (acquired in 2000). Using his detailed survey information, the first known map of the Bay was engraved by William Hole in London and published in 1624.
