Aerial survey is a geomatics method of collecting information by using aerial photography, LiDAR or from remote sensing imagery using other bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet. It can also refer to the chart or map made by analysing a region from the air. This is typically done using aeroplanes, helicopters, UAVs such as the InView Unmanned Aircraft System and in history with balloons. Aerial survey should be distinguished by satellite imagery technologies because of its better resolution, quality and atmospheric conditions. Today, aerial survey is often recognized as a synonym for aerophotogrammetry, part of photogrammetry where the camera is placed in the air. Measurements on aerial images are provided by photogrammetric technologies and methods.
Aerial surveys can provide information on many things not visible from the ground.

Famous quotes containing the words aerial and/or survey:
“But with some small portion of real genius and a warm imagination, an author surely may be permitted a little to expand his wings and to wander in the aerial fields of fancy, provided ... that he soar not to such dangerous heights, from whence unplumed he may fall to the ground disgraced, if not disabled from ever rising anymore.”
—Sarah Fielding (1710–1768)
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
