Aerial survey is a method of collecting information by utilising aerial photography or from remote sensing technology 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 satellites, aircraft, balloons, or kites. Aerial surveys can provide information on many things not visible from the ground.
