Hyperspectral remote sensing: An imaging spectrometry for exploration of earth’s resources and ecosystem management in regional Development
Author(s): Dr. Madan Mohan
Abstract: Hyperspectral imagery contains of earth’s properties which is assimilated in numerous narrow spectral bands using the visible and infrared spectrum of electro-magnetic radiation. In other words, hyperspectral imagery is comprises by hundreds of spectral bands ranging between 5-10 μ m and form a three-dimensional (x, y, λ) hyperspectral data cube. Furthermore, hyperspectral cubes are generated from airborne sensors or satellites as Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and Earth Observation (EO) systems by means of sensors as HYDICE, AVIRIS, and Hyperion which have been developed by NASA. Hyperspectral remote sensing was originally developed for geosciences or earth’s resources exploration as geology and mining of various minerals, historical exploration of human civilisation and so on. Now, its application have also been widespread into fields of surveillance as well as ecology and environment management for sustainable development.
