With the aid of video cameras, approach and berthing maneuvers were recorded on videotape. Two methods were used to estimate the position of the ferry. In the first method, the remote video method, the ferry is positioned in relation to known landmarks, which are located with the aid of optical surveying methods. Information from videotapes is used in conjunction with the results of the optical surveys to provide a plot of the ferry's path as it approaches the berth. In the second method, the radar image method, the vessel's radar screen is recorded on videotape during the ferry's berthing maneuvers. The information from the image of the radar screen provides a heading of the vessel and a distance from the dock for specific times during the berthing maneuvers. This method also gives the position of the ferry as it approaches the berth. This research was conducted at the Edmonds Ferry Terminal, which is located approximately 16 miles north of Seattle.
