Egypt - November 26th, 2009

The fertile Nile River Valley stands out against the surrounding sparsely vegetated Sahara Desert in this FAPAR image of Egypt and the Sinai Peninsula. The Fraction of Absorbed Photosynthetically Active Radiation of such images corresponds to the vegetation index of a given zone.

Most of the Nile River Valley and Delta appears green, ranging between 0.4 and 0.8 on the spectrum of photosynthetic activity,  while the surrounding desert areas show values between 0.0 and 0.2, indicating very low activity. Upon opening the full image, the Nile River can be seen continuing south to Lake Nasser, which shows no signs of vegetation around it.
