Aerial survey

Typical data collected includes aerial photography, Lidar, remote sensing (using various visible and invisible bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet) and geophysical data (such as aeromagnetic surveys and gravity measurements).

It can also refer to a chart or map made by analyzing a region from the air.

Today, aerial survey is often recognized as a synonym for aerophotogrammetry, a part of photogrammetry where the camera is airborne.

Measurements on aerial images are provided by photogrammetric technologies and methods.

In order to carry out an aerial survey, a sensor needs to be fixed to the interior or exterior of the airborne platform with line-of-sight to the target; it is remotely sensing.
