Sharq El Owainat, Egypt

  1. Sharq El Owainat, Egypt
Description

The Landsat satellites were designed to detect landscape changes over time. However, sometimes what Landsat needs to see on the Earth’s surface is no change at all.

This is the story of a key Landsat calibration test site that is being retired as a test site because of the extensive land use change taking place in that area.
