Abstract: For over two decades, hyperspectral imaging (HSI) systems have demonstrated the capability to remotely detect subtle spectral features in reflected and emitted energy from the earth’s surface and atmosphere. These features allow detection, identification, and characterization of materials without the need to spatially resolve materials of interest. This capability has proven crucial to a number of remote sensing applications, from natural resource monitoring to detection of military targets.  Northrop Grumman Aerospace Systems (NGAS) has a long history of developing hyperspectral sensors.  These sensors provide high resolution spectral coverage of wavelength ranges spanning the visible and near infrared (VNIR), short-wave infrared (SWIR) and long-wave infrared (LWIR), and the latest developments in this area have led to very compact, modular high-performance systems.  In this talk Dr. Sandor-Leahy will give an overview of hyperspectral imaging – what it is and how it fits in the general category of EO/IR remote sensing. She will discuss space and airborne hyperspectral sensors and describe results of multiple HSI application studies where both large data volumes and high-dimensional data sets present challenges to accurate analysis.   She will also describe some of the latest developments in HSI instruments and future directions for this sensing technology.
