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.

OceanSat Oceansat (IRS-P4) satellite is a earth observation satellites, operated by Indian Space Research Organisation (ISRO). It is the first satellite primarily built for Ocean applications. This satellite carries Ocean Colour Monitor (OCM) and a Multi – frequency Scanning Microwave Radiometer (MSMR) for oceanographic studies. Oceansat Satellite Specification Oceansat Satellites Series Designation Launch date, Time […]
ASTER Satellite Sensor ASTER stand for Advanced Spaceborne Thermal Emission and Reflection Radiometer, it is operating on the Terra spacecraft. The Terra satellite launched in December 1999 as part of NASA’s Earth Observing System (EOS), a Sun-synchronous polar orbit. ASTER is a cooperative effort between NASA, Japan’s Ministry of Economy, Trade and Industry (METI), and
Panchromatic Sensor The Panchromatic (PAN) Sensor had 5.8 m spatial resolution, as well as stereo capability. Its swath width is 70 m. Revisit time was every five days, with ± 26° off-nadir viewing. Panchromatic Band Band Wavelenth (µm) pan 0.5 to 0.75 Panchromatic Imagery A panchromatic imagery uses a single band image. This imagery is
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
