Remote Sensing
Remote sensing is the science of acquiring information about an object, area, or phenomenon without making physical contact, fundamentally relying on the principles of physics to detect and measure reflected or emitted energy, most commonly electromagnetic radiation. As a field of applied physics, it utilizes sensors aboard platforms such as satellites, aircraft, and drones to collect data from a distance, which is then processed and analyzed to infer characteristics of the Earth's land, oceans, and atmosphere. This interdisciplinary tool is critical for a vast range of applications, including environmental monitoring, weather forecasting, resource management, disaster response, and agriculture.
