Aerial reconnaissance is the process of gathering information about an area from the air, typically using aircraft, drones, or satellites. This technique is often used in military operations, environmental monitoring, and urban planning to assess conditions, map terrain, and identify changes over time. The data collected through aerial reconnaissance can include photographs, videos, and sensor readings. This information helps decision-makers understand the landscape, monitor natural disasters, and plan for future developments. Technologies like drones and satellites have significantly enhanced the capabilities and accuracy of aerial reconnaissance in various fields.
