Remote sensing is a field of study that involves observing and analyzing the Earth's surface from a distance, using various technologies such as satellites, aircraft, and drones. These technologies capture data about the Earth's features, such as vegetation, land cover, water bodies, and infrastructure, which can then be analyzed to monitor environmental changes, track natural disasters, and support decision-making in areas such as agriculture, urban planning, and resource management. Remote sensing plays a crucial role in studying and understanding the Earth's dynamic processes and can provide valuable insights into environmental and societal issues.
