Scientists use satellite images to measure household poverty

Scientists use satellite images to measure household poverty

Science
Jan. 7 (UPI) -- To more strategically allocate resources, set agenda priorities and track the progress of economic initiatives in the developing world, the United Nations is turning to satellite imagery. Researchers at Aarhus University in Denmark have developed methods for quantifying economic living conditions at the household level using high resolution satellite images. "Based on high-resolution satellite images, we can very precisely assess the status of poverty at household level in rural areas in developing countries," Jens-Christian Svenning, a professor and researcher at Aarhus, said in a news release. Using satellite images of portions of rural Kenya as a proof-of-concept test, scientists used several factors to estimate economic living conditions on local farms. Researchers ide...

Dec. 8 (UPI) -- Another day, another scrub. United Launch Alliance once again called off the launch of its Delta 4-Heavy rocket, this time with just 7 seconds to go on the countdown. In an update, ULA said they called off the launch due to an "unexpected condition during terminal count." The mission delay marks the second scrubbed launch in as many days. The company's most powerful rocket was originally scheduled to carry a spy satellite into space on Friday, but a communications error forced ULA to delay the liftoff until Saturday evening. ULA hasn't yet announced when attempt three will take place. During Friday's preflight checks, engineers discovered a "redundant communication link between the control center and the launch site," according to a statement released by ULA. The rocket's...
