Laser Surveying Equipment
The CA has historically owned and been able to loan to member clubs a comprehensive set of equipment for accurately self-surveying croquet courts. A survey at one yard intervals over a whole court (over 1000 measurements) takes three to four hours for a team of three or four people and, after loading the data into a PC, the lawn surface may be seen in 3D.
The computer program is supplied with the equipment and will run on most PCs. it calculates the amount of top dressing required in each yard square to produce a flat (sloping) surface, or (separately) a horizontal surface.
The key instrument, a Robolaser, is self-levelling and transmits a beam that produces a visible spot of light on a target up to 150 feet away (on a dull day). The beam is horizontal to within 1/4 inch in 100 feet and is steered onto the target from either end by means of a remote radio controller. In use, the laser is mounted on a surveyors' tripod and the target (on a pole) is held at a comfortable height.
The equipment usually resides at the CA Office.
At present (February 2019) the equipment is non-operational and the CA is exploring the options available.
All enquires should be made with the CA Office.
