When the photograph of a feature, or any object, or phenomenon on the earth surface is taken from camera mounted on a Remote Controlled (Rc) Aircraft is called Rc Aerial Photography . Digital cameras are commonly used for Rc Aerial Photography .
Equipments for Rc Aerial Photography:

Radio control system in Rc Aerial Photography :
A transmitter and a receiver together makes the radio control system. A radio command is send by the pilot to the receiver which passes the respond to the servo. The servo while moving itself also moves the surface of the plane to which it is attached. The frequency band most frequently used in a Rc aircraft is 72MHz.A radio cantrol system can handle 2 separate radio functions.
Rc Aerial Photography with the Rc Gliders:
Slope gliders and thermal glidrers are two form of gliders used in Rc Aerial Photography . The slope glider is cast away from the hill.When it is thrown in the air, it starts flying with the wind current. Thermal gliders are flown directly into warm air currents (thermals) as their name indicates. Handlaunch airplanes are thrusted off by hand and flown in a similar way as that of thermal gliders.All kind of gliders needs upwaes rising of wind in order to float.
Use of Rc Aerial Photography :
- Mapping properties for sale or buying
- To find out the stages of development, construction of roads or building,
- Agricultural mapping
- Disaster mapping
- Mapping for advertisement
- Archaeological mapping
- Capturing special events like Olympics
- Website development
Advantages of Rc Aerial Photography:
- Cheap to buy and maintain equipmants
- Less affected by atmospheric abstractness
- Distortion occurs much less
- Travelling to and from airfield is not needed.
Disadvantages of Rc Aerial Photography:
- Since the weight is less, it is affected by speedy wind movements.
- Low lying features may create an obstacle.
Rc Aerial Photography is increasingly used recently because of the advantages associated with it and is hoping to become more popular in near future.
