Hyperspectral Sensor Optical Sensors divided into 3 basic classes: Panchromatic, Multispectral, and Hyperspectral. Multispectral Sensor typically collects a few, wide (100-200 nm), and possibly noncontiguous spectral bands. Hyperspectral sensors typically collect hundreds of narrow (5-20 nm) contiguous bands. The name hyperspectral implies that the spectral sampling exceeds the spectral detail of the target. In practice, […]

Multispectral Scanner Sensor The Multispectral Scanner System (MSS) Sensor were line scanning devices observing the Earth perpendicular to the orbital track. The cross-track scanning was accomplished by an oscillating mirror; six lines were scanned simultaneously in each of the four spectral bands for each mirror sweep. The forward motion of the satellite provided the along-track

Thematic Mapper Sensor What is Thematic Mapper? The Thematic Mapper (TM) is an advanced multispectral scanning, Earth resources Sensor. Its designed to achieve higher image Resolution, sharper spectral separation, improved geometric fidelity and greater radiometric accuracy and resolution than the MSS Sensor. TM sensor records reflected and emitted electromagnetic energy from the visible, reflective-infrared, middle-infrared,
