Abstract

An aquatic vegetation harvesting system for clearing aquatic vegetation from bodies of water is disclosed. The system comprises a harvesting device, a receiver on the vessel for receiving position data from a global positioning system satellite, a storage device for storing digital map data representing a predetermined vegetation harvesting plan for the body of water, and a processor for receiving position data and digital map data wherein the processor continuously outputs harvesting signals derived from comparing position data and digital map data to the dispensing system to the harvesting device or to a user display such that the harvesting device may be activated to harvest the vegetation. The system also provides a method in which position data representing a location of the vessel on the body of water are stored in a storage device along with an on-off status indicator for the harvesting device associated with each location such that the harvesting operation performed at each location can be reviewed after the vessel is directed over the body of water.
