This Surface Plotting Manual is promulgated for the purpose of setting forth the plotting procedures, symbols, and techniques which will aid in standardizing the portrayal of the surface picture. In accomplishing this purpose you will find the background material, equipment, and aids necessary to the maintenance of the surface plot will be discussed in connection with the true and relative presentation.
The manual is written on the assumption that its readers are entering an entirely unfamiliar field and consequently introduces the necessary material in a sequence which will be most beneficial for this category of individuals. Endeavor has been made to lead the prospective plotter through the logical succession of events and explain in simple language the problems to be met and methods of solution with the following objectives in mind:
To acquaint the reader with the problem of surface plotting.
To explain to the reader how to use the plotting equipment he will be furnished.
To provide the reader with standard methods of plotting.
To acquaint the reader with standard plotting symbols and abbreviations.
To give the reader practice in laying out and completely labeling the tracks in order to present a clear understandable plot that will accurately portray the events that take place in the area within radar range of the ship.
To provide the guides for sufficient practice in the above procedure to establish proficiency.
