Aerial survey

Method of collecting geophysical data from high altitude aircraft

Aerial survey is a method of collecting geomatics or other imagery data using airplanes, helicopters, UAVs, balloons, or other aerial methods. Typical data collected includes aerial photography, Lidar, remote sensing and geophysical data. It can also refer to a chart or map made by analyzing a region from the air. Aerial survey should be distinguished from satellite imagery technologies because of its better resolution, quality, and resistance to atmospheric conditions that can negatively impact and obscure satellite observation. 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.
