Hyperspectral Remote Sensor -sensing Disasters From Space Before They Happen

Sunday, October 25, 2009 - 11:49 in Earth & Climate

One small step for mankind, one giant leap for ... averting natural and man-made disasters? A new Tel Aviv University technology combines sensors in orbit with sensors on the ground and in the air to create what they call a "Hyperspectral Remote Sensor" (HRS) which will provide advance warnings about water contamination after a forest fire, alert authorities of a pollution spill long before a red flag is raised on earth - or even tell people in China where a monsoon will strike.  The HRS simultaneously acquires hundreds of optical images, each from a different frequency, that enable a "spectral assessment" from distances high in the air via airplanes and in orbit using satellites. This raw data is then processed to yield sophisticated thematic maps. read more
