Satellite surveillance refers to the use of satellites in orbit around the Earth to monitor and collect data about various activities and environments. These satellites are equipped with advanced sensors and cameras that can capture images and gather information on land use, weather patterns, and even military movements. This technology is utilized by governments, researchers, and private companies for purposes such as environmental monitoring, disaster response, and national security. By providing a broad and detailed view of the Earth's surface, satellite surveillance plays a crucial role in understanding global changes and making informed decisions.
