They’re made to be identified in the distance, as well as the colours, shapes, markers, lights, and sounds of the numerous aids deliver key navigational info. Aids to Navigation comprise, among other items, lighthouses, nun and many buoys, and daymarks; every kind has its own symbol on graphs.

To plot your path on a newspaper, simply spend the latitude and longitude coordinates from the GPS. Locate the corresponding coordinates onto the borders of the chart.

Normally, the longitude coordinates are around the top and bottom borders, and latitude coordinates are all on the left and right borders; a few graph novels have graph perspectives organized at other angles for clarity or space purposes. With a straightedge, create a light pencil mark in which the lines intersect.
