Multi- and Hyperspectral Remote Sensing

Multispectral imaging enables the mapping of materials on planetary surfaces with unique spectral features recorded by the sensor’s spectral channels. The added power of a hyperspectral sensor is in being able to uniquely identify materials that have spectrally diagnostic absorption features within the spectral range of the sensor.  Processing approaches that have been developed for multi- and hyperspectral sensors in the solar reflective region of the visible and near-infrared to short-wave infrared (VNIR-SWIR, 0.4 – 2.5 mm) take advantage of the higher spectral dimensionality of these datasets. Where the surface materials in question have diagnostic absorption features these approaches enable the comprehensive mapping of those materials
