High density air shooting unit by using gps and ins

The present invention relates to an air photography device which can perform air photography by combining an air ship automatic photography system, which can automatically and rapidly acquire images including information on urban changes of an ever-changing city, with a global position system (GPS). To be more particular, the air photography device: can acquire image data and spatial information by tracking a photography plan course coordinate inputted in a computer without dispatching manpower to a field through the automatic photography system; can acquire clear and accurate photographed images by calculating a photography distance from a subject using an aircraft altitude and a photography angle and regulating a photography rate according to the distance; can allow a user to easily understand the surrounding environment of a specific area because the user can check not only plane images but also side images of the specific area through a numerical map and, in turn, can maximize user convenience of the numerical map; and can release inconvenience of editing the acquired photographed images after taking plane and side photographs of the same geographic feature from the aircraft.
