Land marking device

A land marking device capable of marking a survey point on the ground, said device comprising:

• (a) a housing adapted to be suspended from an aircraft;
• (b) a receptacle inside the housing, the receptacle being adapted to accommodate at least one marker in the form of a rigid elongated member;
• and
• (c) a mechanism cooperating with the receptacle for ejecting the marker from the receptacle towards the survey point, when the housing is positioned above the survey point, the mechanism being capable of applying sufficient force to the rigid elongated marker in the lengthwise direction of the marker as to propel the marker lengthwise toward the survey point with sufficient velocity as to partially penetrate the ground at or near the survey point on the ground whereby the survey point is securely marked.
