Egypt, without borders

EOSnap celebrates our 6000th post by focusing on the new “borders” feature of the Chelys Satellite Rapid Response System (SRRS). The feature allows users to download satellite images that show not only a true, traditional view of the terrain below, but also the borders of countries. The feature is particularly useful for seeing the outline of land despite cloudcover. It can also be used to show the location of lakes.

In the main image, the border between Egypt and Sudan is clearly visible as a horizontal line. The contours of Lake Nasser, which would otherwise be invisible except for its southern tip due to heavy cloud cover (see thumbnail image “Egypt, without borders” for a look at the original, borderless image), are easily distinguishable, highlighted in blue. The thumbnail image of Mozambique shows the country’s shoreline despite an area of convection, in this case a potential area of cyclone formation, looming over the coast. The thumbnail image of Bolivia and Peru focuses on Lake Titicaca, and clearly shows where the lake is divided between the two countries. The thumbnail image of southern USA, in addition to sediments from the Mississippi River, shows the border between Louisiana (right) and Texas (left), as well as the Toledo Bend Reservoir, despite the thick clouds covering the upper half of the image.

Plume of Dust Across Ethiopia and Sudan

Ethiopia and Sudan – December 25th, 2012

Visible in the lower right hand corner of this image is Lake Tana, located in Amhara Region in the north-western Ethiopian Highlands. The lake is approximately 84 kilometers long and 66 kilometers wide, with a maximum depth of 15 meters, and an elevation of 1,840 meters. Near the lake is a plume of dust blowing towards the northwest, almost reaching the Nile River, which flows northward across Sudan on the left side of the image.

Contours of Lake Nasser, Egypt and Sudan

Egypt – November 16th, 2012

Lake Nasser is a vast reservoir on the Nile River in southern Egypt and northern Sudan. Strictly, “Lake Nasser” refers only to the much larger portion of the lake that is in Egyptian territory (83% of the total), with the Sudanese preferring to call their smaller body of water Lake Nubia. Here, the Sudanese part appears greenish due to sediments and algae, while the Egyptian part appears dark blue.

It is one of the largest man-made lakes in the world. The lake is some 550 km long and 35 km across at its widest point, which is near the Tropic of Cancer. It covers a total surface area of 5,250 km² and has a storage capacity of some 157 km³ of water. The area of Sudan-administered Wadi Halfa Salient was largely flooded by Lake Nasser. Visible near the left edge are the Toshka Lakes, created by overflow.

Dust Over Red Sea Between Saudi Arabia and Sudan – October 20th, 2012

Red Sea – October 16th, 2012

Dust blows across one of the narrower parts of the Red Sea, near its center, between Saudi Arabia (right) and Sudan (left). The dust appears thickest near the Saudi Arabian coast. In the full image, wavelike patterns caused by air currents can be observed in the dust just off the shoreline.

Thick Dust Over Red Sea

Red Sea – September 1st, 2012

A thick cloud of dust spreads over the Red Sea. The dust appears to originate on the African continent, although dust storms on the Arabian Peninsula are also very common. Here, the dust is thickest off the coast of Sudan (above), although it also blows over the coast of Eritrea and spreads southward towards the Bab-el-Mandeb strait.
