Here’s looking at you: remote sensing from space

Those eyes in the sky are seeing plenty. Researchers are finding more and more ways to use that data to solve the world’s great challenges and even save lives. An article in the latest issue of The Scientist detailed several recent projects. Among them: “With funding from NASA, Frank Muller-Karger, director of the Institute for Marine Remote Sensing at the University of South Florida, and his colleagues purchased more than 1,400 Landsat 7 images acquired between 1999 and 2003 in order to outline and classify the world’s shallow-reef ecosystems. Completed in 2007, the Millennium Coral Reef Mapping Project produced the first uniform map of all the coral reefs around the world at a 30-meter-pixel resolution. The United Nations’ World Conservation Monitoring Centre is now refining the map in order to use it for global conservation efforts.” The information the team has gathered is also useful for fish and wildlife managers and others with interests in monitoring ocean water quality.
