Satellite Imagery: Principles, Applications, and Future Trends

Definition and Basic Principles Satellite imagery refers to images of Earth (or other planets) collected by orbiting satellites. These images are a form of remote sensing, meaning the data are acquired from a distance without direct contact. Satellites carry sensors that detect electromagnetic radiation reflected or emitted from the Earth’s surface. Most imaging satellites use passive sensors that rely…
