Heezen's highlands: People who chart the ocean floor draw up landscapes no one has seen, using machines that send out sound waves and invisible rays

Article Abstract:

The earliest ocean floor charts were made possible by the increasingly high resolution of echo-sounders during the 1950s. A combination of observed measurement, logical extrapolation , approximation and imaginative guesswork was used. Marie Tharp and Bruce Heezen produced the first coherent relief map of the Atlantic in 1952. The maps have been greatly refined in data and technique over the years.

Venus's voyeurs

Article Abstract:

Pictures of distant planets transmitted to Earth by spacecraft allow audiences to see beautiful landscapes but constructing the images involves choices that traditional landscape painters would recognize. The technique involves synthetic aperture radar scanning images which go through a pictorial rendering process that includes adding false colours to the final image.
