Quick Answer
Elevation plays a critical role in survival navigation by providing a means to associate terrain features with a map and to estimate one's location. It also aids in understanding the weather patterns and potential hazards. Proper use of elevation information can significantly enhance one's ability to navigate.
Understanding Elevation and Terrain Features
When navigating, it is essential to associate terrain features with a map. Elevation helps in identifying key features such as ridges, valleys, and mountains. By understanding the relief of the terrain, you can estimate your location by associating the features on the map with those on the ground. For example, if you see a prominent mountain on the map, you can use its elevation to help estimate your position if you can see the mountain from your location.
Using Elevation to Estimate Location
To estimate your location using elevation, you need to know the elevation of your current position and the elevation of a feature on the map. Use a barometer or an altimeter to measure your current elevation and consult a map to find the elevation of the feature. Subtract your current elevation from the elevation of the feature to estimate the distance to the feature. This technique is called “dead reckoning” and is a basic navigation method.
Avoiding Hazards with Elevation Information
Elevation also aids in understanding weather patterns and potential hazards. Higher elevations often experience more severe weather conditions, and it is essential to be aware of these conditions when navigating. By using elevation information, you can estimate the likelihood of encountering hazards such as snowstorms, avalanches, or strong winds. This information will help you make informed decisions about your route and ensure a safer journey.
