Aerial survey technicians have expertise in conducting surveys from the air using aerial photography with both still and video cameras. They can also employ remote sensing imagery such as infrared gamma or ultraviolet technology. Most aerial surveys use planes but in some instances surveys may be done from helicopters and hot air balloons.
Aerial surveys are employed when there is a need to collect information on things that are not readily visible from the ground because they are more efficient than those surveys done on the ground. Aerial surveys are used for many purposes including surveys of fisheries land surveys for the purpose of measuring vegetation and ground cover surveys and keeping logs of wildlife and insect populations and in some cases surveys for the purpose of reconnaissance.
Air survey technicians must be able to identify the specific area that will be covered in the survey and prior to the start of the survey they must confirm that weather conditions are amenable to the nature and purpose of the survey. It is vital that they be capable of measuring wind conditions and visibility in the designated area of the survey route. Therefore they must have background and training in weather prediction as well as in the most recent GPS technology to track the position of the aircraft.
