What is terestrial navigation?

Terrestrial navigation is the process of determining one's position on the Earth's surface using landmarks, maps, and various navigational tools. It relies on visual references, such as identifiable geographical features, as well as techniques like dead reckoning and triangulation. This method has been traditionally used by sailors, pilots, and hikers before the advent of modern technology like GPS. It emphasizes the importance of understanding the environment and the ability to interpret physical cues for accurate navigation.
