Abstract
A system for an aerial land marking and surveying is disclosed. The system comprises an aircraft carrying a GPS receiver and a land marking device capable of physically marking a point on the ground identified by a computer program. A new method of an aerial land marking and surveying and a land-marking device for carrying out the method are also disclosed.
Claims12
An aerial land marking system, the system comprising:
- a) an aircraft capable of hovering above a selected area on the ground;
- b) a land-marking device capable of being suspended from the aircraft, the land-marking device capable of marking a survey point on the ground;
- c) a GPS (global positioning system) receiver capable of being suspended from the aircraft and situated above the land-marking device when thus suspended, the GPS receiver being capable of receiving position data;
- and
- d) a computer communicatively connected to the GPS receiver and the land-marking device for calculating and storing coordinates of the marked survey point.
2 more elements
A method of aerial land marking, said method comprising the steps of:
- flying an aircraft carrying a land-marking device to a position above a location on the ground,
- lowering the land-marking device to a point proximate to the location on the ground,
- securing a marker from the land-marking device at a point on the ground,
- calculating and recording coordinates for the point on the ground.
1 more element
A method of aerial land marking, the method comprising steps of:
- a) positioning a land-marking device and a GPS receiver over a survey area by means of an aircraft;
- b) lowering the land-marking device and the GPS receiver such that the GPS receiver is situated above the land-marking device;
- c) activating the GPS receiver whereby the latter receives position data;
- d) securing a marker at or near a survey point of the survey area by using the land-marking device;
- and
- e) calculating and recording coordinates of the marked survey point.
