Radar Mapping Techniques and Applications

Paula Messina

New York City, Long Island and Vicinity (as imaged during NASA's SIR-C SL1 Mission, April 1994)

At the top is a visible-light photograph of the area, taken by Shuttle astronauts at 3:00am on April 20, 1994. The bottom image is a radar view of the same area taken at 3:00am on April 16, 1994.

Notice how the radar image shows a great amount of surface detail, despite night acquisition. Note, for example: the relief of the terminal moraine on Long Island's North Shore; the surface waves on the Atlantic Ocean; and the flat network of highways around the City.
