Chart Projections, Plotting and Global Time Keeping
Assignment Sheet No. 4.2.1A
The purpose of this assignment sheet is to familiarize the student with chart projections
and plotting techniques. It is also necessary for navigation and coordination purposes that
time be expressed in a standardized form. To achieve this, an understanding of the global
timekeeping system is required.
