Surface Plotter

Surface plotters are navigational instruments used for plotting and recording the position of a vessel or aircraft on a chart or map. They are commonly used in marine and aviation industries for navigation and route planning.

Surface plotters typically consist of a transparent base with a grid or scale markings, a movable arm or cursor, and a plotting pencil or pen. The base is placed over a chart or map, and the arm or cursor is used to mark the vessel or aircraft's position by aligning it with the appropriate grid or scale markings. The plotting pencil or pen is then used to mark the position on the chart or map.

These instruments are essential for accurately tracking and recording the movement of a vessel or aircraft, allowing navigators to determine their current position, plan routes, and make informed navigational decisions. They are often used in conjunction with other navigational tools, such as compasses, GPS systems, and radar.

In the supply group "Instruments And Laboratory Equipment," surface plotters are classified under the supply class "Navigational Instruments." This class includes various instruments used for navigation purposes, such as compasses, sextants, nautical charts, and navigational calculators.

Overall, surface plotters are valuable tools for navigators, providing a visual representation of a vessel or aircraft's position on a chart or map, aiding in safe and efficient navigation.
