    The four near infrared orbital images show the same survey line over time. From left to right the images were taken in 1972, 1986, 1988, and 1992. The zigzag features are the chevron sand features and the different shades correspond to material of different compositions that have different reflectances in the near infrared. The moving of the chevron over time is captured in these remote sensing images.
