The French SPOT satellite data (20-m resolution) were obtained on 28 July 1989 and provides a view of the mapped region from space. The false-color infrared image shows more densely vegetated areas as brighter red tones. When compared with the glacial geology map, the older Sagavanirktok-age glacial landscapes have few lakes and redder tones indicating more dense vegetation, and the younger Itkillik-age glacial surfaces that have more lakes and grayer colors.
This image is at 20-m resolution, and includes SPOT bands 1 (green, 0.50 – 0.59 µm), 2 (red, 0.61 - 0.68 µm), and 3 (near infrared, 0.78 - 0.89 µm).
