Optical Remote Sensing

Optical remote sensing involves capturing images of Earth's surface using cameras or sensors that detect sunlight reflected from objects. These sensors can be mounted on satellites, airplanes, or drones. They record data in visible, near-infrared, and other wavelengths, enabling us to analyze land use, vegetation health, water bodies, and urban development from afar. This technology provides crucial information for environmental monitoring, agriculture, disaster management, and urban planning, offering a comprehensive view of the Earth's surface without physical contact.
