The Horus Project is a "Do It Yourself" drone project. The drone is used for surveying purposes. An airplane radio controlled model, is automated to fly a route defined by GPS waypoints. On each waypoint of the route, a high resolution picture is taken from the on board digital camera.
The Geographical Information System SavGIS is used for the postprocessing, allowing the orthorectification of the pictures so that they can be placed on a topographical map.
The take off and landing of the drone is done in manually controlled flight. The surveying part of the flight is fully automatic, including the triggering of the camera.

The UAV itself is a modified MovieStar beginner model from Multiplex:

Aerial pictures taken in France during a test flight in April 2006 are integrated in the topographical Map using a
