Definition & Meaning of "remote sensing"

What is "remote sensing"?

Remote sensing is the process of collecting information about the Earth's surface from a distance, typically using satellites, aircraft, or drones. This technology captures data through sensors that detect and measure reflected or emitted radiation, such as light or heat, from the Earth's surface. The data collected can be used to create images, maps, and analyses that help scientists and researchers study land use, monitor environmental changes, track weather patterns, and assess natural disasters. Remote sensing is valuable for understanding and managing natural resources, as well as for scientific research and environmental monitoring.
