GIS & REMOTE SENSING
Remote sensing (RS) is an art and science of obtaining information about physical characteristics of an area by measuring its reflected and emitted radiation at a distance to help of Satellite or Aircraft.

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 Imaging 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
Summary: – The Thematic Mapper (TM) is a multispectral scanning sensor that was introduced aboard the Landsat 4 and Landsat 5 satellites. The TM sensor captures imagery in seven spectral bands, with a spectral and spatial resolution. Thematic Mapper Sensor: Landsat TM The Thematic Mapper (TM) is a powerful imaging sensor that was part of
