Remote sensing is the technique of acquiring information about an object or area without direct physical contact. It uses sensors on platforms like satellites or aircraft to detect and measure electromagnetic radiation reflected or emitted from the target.
Remote SensingRemote sensing is a powerful tool in various fields. It involves obtaining data about the Earth's surface, atmosphere, or other objects from a distance.How it works: Specialized sensors are mounted on satellites, aircraft, or drones. These sensors detect different wavelengths of electromagnetic radiation. For example, visible light, infrared, and microwave wavelengths. When the radiation hits an object, some is reflected, absorbed, or emitted. The sensor captures this reflected or emitted radiation and converts it into digital data.Applications:- Environmental monitoring: Tracking changes in land use, deforestation, and water quality.- Agriculture: Assessing crop health, soil moisture, and nutrient levels.- Disaster management: Detecting wildfires, floods, and earthquakes for early warning and response.- Mapping: Creating detailed maps of terrain, cities, and natural resources.Remote sensing has revolutionized the way we understand and interact with our world, providing valuable insights for decision-making and research.
