Aerial surveys can provide information on many things not visible from the ground. Aerial surveying is a method of collecting geometrics or other imagery by using airplanes, helicopters, UAVs, balloons or other aerial methods. Typical types of data collected are aerial photography, LiDAR, remote sensing using various visible and invisible bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet and also geophysical data such as aeromagnetic surveys and gravity. It can also refer to the chart or map made by analyzing a region from the air.
Aerial survey should be distinguished from satellite imagery technologies because of its higher resolution, quality and atmospheric conditions. Today, aerial survey is sometimes recognized as a synonym for aero photogrammetry, part of photogrammetry where the camera is placed in the air. Measurements on aerial images are provided by photogrammetric technologies and methods.
