Remote sensing is the process of collecting information about an object or area from a distance, typically using satellites or aircraft. This technology captures data through various sensors that detect electromagnetic radiation, such as visible light, infrared, and radar. The information gathered can be used to monitor environmental changes, assess natural resources, and support disaster management. The data obtained through remote sensing can be analyzed to create detailed maps and models of the Earth's surface. Applications include tracking deforestation, urban development, and climate change. Organizations like NASA and NOAA utilize remote sensing to enhance our understanding of the planet and improve decision-making.
