A golf information system which provides for automatic detection of a golf cart position on a golf course by either a golfer on the cart or personnel in a golf course clubhouse. In one embodiment, a differential global positioning satellite receiver (DGPS) is utilized to detect a golf cart position and the detected position is compared with a digital data map where it is further transmitted to a golf cart display as well as to a clubhouse display, either automatically in a timed manner, or upon prompting by a golfer or clubhouse personnel. The system can be further used to send speed of play messages to a golfer from a clubhouse in order to speed up play, and can also be used to send emergency and acknowledgement signals from a golfer to a clubhouse in response to emergencies or messages displayed to the golfer. Furthermore, advertizing messages can be displayed to a golfer from a clubhouse in response to clubhouse initiated signaling. |
