Satellite imaging is a technology that uses satellites orbiting the Earth to capture images of the planet's surface. These images can show various features, such as land use, vegetation, and urban development. The data collected can be used for purposes like environmental monitoring, agriculture, and disaster management. The images are taken using different types of sensors, which can capture visible light, infrared, and other wavelengths. This allows for detailed analysis of the Earth's surface and helps scientists and researchers understand changes over time, making satellite imaging a valuable tool in fields like geography and climate science.
