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.
In below list of Remote sensing Analysis Tutorial.
Satellite Systems A Satellite system is composed of a scanner with sensors and a satellite platform. Sensors are made up of Detectors. In a satellite system, the total width of the area on the ground covered by the scanner is called swath, or field of view (FOV). Landsat and SPOT satellites are two important date […]
Ideal Remote Sensing System The different acquisition techniques of Remote Sensing (RS) can be distinguished according to the type of the Electromagnetic Radiation used. There are remote sensing systems working with 2 types, (A) Passive Remote Sensing system, and (B) Active Remote Sensing system. Basic components of an ideal Remote Sensing system Passive Remote Sensing
Electromagnetic Radiation (EMR) What is the Electromagnetic Radiation? Electromagnetic Radiation (EMR) or Electromagnetic energy is the energy propagated in the form of an advancing interaction between electric and magnetic fields. It travels with the velocity of light. Visible light, ultraviolet, and infrared rays, heat, radio waves, X-rays all are different forms of electromagnetic energy. EMR
Electromagnetic Spectrum (EMS) What is Electromagnetic Spectrum? Electromagnetic Spectrum is represented by Electromagnetic waves. It’s characterized by their Wavelength or Frequency, linked by the speed of light. The frequency is associated with energy. High frequency is high energy. The Electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 hertz.
Chandrayaan 2 Mission Chandrayaan-2 mission represents a significant technological leap compared to the previous missions of ISRO (Indian Space Research Organisation). It comprised an Orbiter, Lander and Rover to explore the unexplored South Pole of the Moon. The main purpose of this mission study of topography, seismography, mineral identification and distribution, surface chemical composition, thermo-physical
