Aerial imagery is the process of capturing photographs or videos of the Earth's surface from an airborne platform, such as satellites, drones, airplanes, or helicopters. This imagery is used for various purposes, such as mapping and surveying, environmental monitoring, urban planning, agriculture, disaster management, and defense and security. Aerial imagery can provide high-resolution and detailed images of landscapes, infrastructure, and natural resources, allowing for analysis and decision-making in a wide range of industries and fields.
