- Aerial survey
Aerial survey is a
geomaticsmethod of collecting information by utilising aerial photographyor from remote sensing imageryusing 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, and in history with balloons. Aerial survey should be distinguished by satelliteimagery technologies because of its better resolution, quality and atmospheric conditions. Today, aerial survey is often recognized as a synonym for aerophotogrammetry, part of photogrammetrywhere the camerais 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.
Aerial surveys are used for:
* Fishery surveys
* Land survey
* Monitoring wildlife and insect populations, called aerial
* Monitoring vegetation and ground cover
Aerial survey uses a measuring camera where the elements of the interior orientation are known, but a camera that has much larger
focal lengthand filmand more lenses are used.
