In naval terminology a Plot is a graphic display that shows all collated data from a ship's on-board sensors i.e. radar, sonar and EW systems. They also displayed information from external sources i.e. other vessel or aircraft reports. There are four different types of plot, each with varying capabilities i.e. range, depending on their role;
Air Plot: Used for tracking air contacts i.e. planes and EW information
- Can be used in naval gunfire support missions to plot unidentified contacts and keep track of friendly forces
Sub-Surface Plot: Used for tracking contacts below the surface of the water i.e. submarines
General Operations Plot: Used for tracking shipping on a large scale chart. Was also used to display exercise boundaries, airlanes and other significant features of maritime interest. In the R.A.N. the scale used was generally 5 miles to 1 inch OR 10 miles to 1 inch.
