System and method for providing an excavation characteristic associated
with an earthmoving machine. In one embodiment, a radio frequency
identification (RFID) tag associated with an attachment mounted to an
earthmoving machine may be identified. An optical benchmark signal may be
detected, by an optical receiver. The position of the attachment relative
to the earthmoving machine may be determined based, at least in part, on
identification of the RFID tag. The position of the attachment may be
provided to an operator of the earthmoving machine
