A View from Space: Multi-spectral and Hyperspectral Data


The first satellite was launched in 1957 by the Soviets (Sputnik 1), quickly followed by one launched by the Americans (Explorer 1).  And so began a new way to look at the Earth.  Today more than 2,200 satellites orbit the Earth, many providing a steady stream of scientific data. Accurate satellite imagery may be the …

First Look: Hyperspectral Images from Neuquén neoBASIN Project

I thought you might be interested in seeing some early data from our project in Argentina’s Neuquén Basin. Shown below are three side-by-side comparisons of airborne multi-spectral data. The images on the left were taken with a satellite owned and operated by NASA known as ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer). ASTER data is readily …

Satellite Imagery Reveals Unknown Pyramids


Yet another application of airborne multi-spectral imaging. Even with the lower channel counts (and more limited ‘fingerprinting’ capabilities) of satellite-based remote sensing systems, U.S. archeologists were able to use data from NASA and commercial satellites to identify more than 17 pyramids, 1,000 tombs and other buildings dating to the time of the Pharaohs. The infrared …
