What is one technique used for land navigation that involves using a prominent feature?

The technique involving the use of a prominent feature for land navigation is known as a handrail. This method relies on identifiable landmarks along a route to guide navigation and helps individuals stay oriented in their environment. By following a natural or manmade feature, such as a road, fence line, river, or ridge, a navigator can maintain their course while using the landmark as a reference point.

Handrails are beneficial because they are often visible from a distance and provide a reliable means of ensuring that you are moving in the desired direction. This method reduces the cognitive load of constantly checking a map and allows for a more intuitive approach to navigation, making it particularly useful in unfamiliar terrain.

Other methods such as coordinate navigation and triangulation focus more on the mathematical or theoretical aspects of determining positions rather than emphasizing the practical use of visible landmarks, while map overlay refers to the process of using different map layers together to analyze geographic information, not a direct method of navigation in the field. Thus, handrail navigation stands out as a practical and effective technique in land navigation.
