New Borders Feature in Action – January 27th, 2013 – EOSnap Celebrates its 6000th Post!22.5N 31.7E
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.
