aerial survey
Overhead terrain assessment
An aerial survey is the collection of data from above ground level, typically using aircraft, drones, or satellites.
The technique captures photographs, measurements, or sensor readings of terrain, structures, or resources: The aerial survey revealed previously unknown archaeological sites.
Used extensively in mapping, agriculture, construction, and environmental monitoring.
