Remote Sensing: A Comprehensive Overview and Its Key Applications
Remote Sensing: A Comprehensive Overview Remote Sensing: A Comprehensive Overview Introduction to Remote Sensing Remote sensing is a powerful and widely used technology that allows for the collection of data and information about the Earth's surface without direct contact. This method relies on sensors to detect and measure electromagnetic radiation reflected or emitted from objects, surfaces, or areas. By using remote sensing, researchers can observe and monitor various features of the Earth, analyze environmental changes, and make informed decisions in multiple fields such as agriculture, meteorology, geology, oceanography, and disaster management. In its broadest sense, remote sensing refers to the practice of acquiring information from a distance, using satellites, aircraft, or ground-based sensors. The technology has evolved significantly over time, particularl
