How is True North depicted in a Declination diagram?

True North is depicted in a declination diagram as a line with a star on the end of it. This symbol is used to indicate the direction of True North in relation to magnetic north and provides essential information for navigation. The star represents the geographic North Pole, helping users understand their orientation on topographic maps. When using these diagrams, recognizing this marking aids in accurately aligning maps with the Earth's coordinates, which is crucial for successful navigation. Understanding the representation of True North is fundamental for ensuring that navigational calculations are precise, particularly in environments where magnetic variation occurs.
