A system for measuring the amount of crop material located on a field to be harvested uses a scanning laser device. The scanning laser device has a transmitter fo r emitting electromagnetic radiation, a receiver for receiving reflected radiation from the crop material and providing resolution in terms of location and/or angle from whi ch the reflected radiation was received. The receiver also generates an intensity signal indicating the intensity of the reflected electromagnetic radiation. A controller is in communication with the scanning laser device and determines the amount of th e crop material located on the field on the basis of the crop material location signals and the intensity signals received from the receiver.
