Aerial imagery refers to photographs or images of the Earth's surface that are taken from an elevated perspective, typically from an airplane, helicopter, or drone. These images are often used in various fields such as cartography, urban planning, environmental monitoring, and agriculture. In the context of growth, aerial imagery can be used to monitor changes in land use, vegetation, and infrastructure over time. For example, satellite imagery can be used to track changes in agricultural land, such as the expansion of crops or the clearing of forests. Aerial imagery can also be used to monitor changes in urban areas, such as the growth of buildings, roads, and other infrastructure.
