Earth Observation taken by the Expedition 29 crew

ISS029-E-037471 (3 Nov. 2011) --- Egypt?Israel borderlands, northern Sinai Peninsula and northern Negev Desert are featured in this image photographed by an Expedition 29 crew member on the International Space Station. A clearly visible line that marks approximately 50 kilometers of the international border between Egypt and Israel?10-60 kilometers from the Mediterranean Sea to the northwest (not shown)?crosses the center of this photograph from left to right. The reason for the color difference is likely the slightly higher level of grazing by the animal herds of Bedouin herdsmen on the Egyptian side of the border. A major highway also follows the border, making the demarcation more prominent in this recent image taken from the space station. A patch of the Gaza Strip appears under scattered cloud at far right. In the arid to semiarid climate of the region illustrated in the image the natural grass vegetation is sparse at best. Irrigated commercial agriculture in Israel nearest the Mediterranean coast appears as a series of large angular patterns and circular center pivot fields, with darker greens indicating growing crops (right). Smaller plot sizes appear on the Egyptian side of the border at upper right. The image shows how the active sand dunes, which dominate most of the landscape in this view, mark the southern limit of the agriculture.
