Remote sensing receives data through various techniques that capture information about the Earth’s surface from a distance. This process primarily involves satellites, aircraft, and drones equipped with sensors. These sensors detect reflected sunlight or emitted radiation from the Earth’s surface, which can include various wavelengths such as visible light, infrared, and microwave. The collected data is then transmitted back to ground stations, where it is processed and analyzed using specialized software. Remote sensing is widely used for monitoring environmental changes, land use, agriculture, and disaster management, providing valuable insights for decision-making and resource management.
