Abstract: A method for measuring physical properties, e.g., firmness, smoothness, trueness, green speed, of a playing surface on a golf course, includes performing measurements via a measurement apparatus. The measurement apparatus includes a spherical sensor, which in turn includes an accelerometer for measuring motion data relating to motion of the spherical sensor, a memory for storing the motion data, and a communication module for wirelessly transmitting the motion data to a computing device.

Abstract: A golf course maintenance system and method which comprises the input of a golf course and its shape, size and parameters into a computer-like system. The course is segmented into teeing grounds, fairways, one or more rough areas, water hazards, bunkers, and putting greens. Each such component of the holes and course is calculated into square foot or square yards surface area. Each such component is then calculated for maintenance purposes based upon cost components for maintenances, namely, cost and quantity of labor and Consumables such as fuel, energy, water, chemicals, fertilizers. The Course Officials can input into a CPU connected to a display screen the approximate configuration, length, width, and location of teeing grounds, fairways, rough, water hazards, bunkers, and putting greens. Each of these Course Components is then associated with a set of Processes to maintain them and each Process is associated with cost factors, e.g., labor, consumables resources such as fuel and water, etc.
