Satellite data refers to information collected by satellites orbiting the Earth. These satellites use various sensors to capture images and measurements of the Earth's surface, atmosphere, and oceans. This data is crucial for monitoring weather patterns, tracking environmental changes, and managing natural resources. The information gathered from satellites can be used in various fields, including agriculture, urban planning, and disaster response. For example, remote sensing technology allows scientists to analyze land use and vegetation health, helping farmers make informed decisions. Overall, satellite data plays a vital role in understanding and managing our planet.
