What are dangers of relying solely on digital mapping?

Inaccurate Representation of Terrain

Digital maps often lack the level of detail and nuance found in traditional topographic maps and contour lines. While digital maps can show elevation changes, they may not accurately represent the terrain’s complexity, such as steep slopes, cliffs, or ravines. This can lead to incorrect assumptions about the route’s difficulty and potential hazards.

Signal Loss and GPS Malfunction

Relying solely on digital mapping can also put you at risk if your device’s GPS signal is lost or blocked. This can happen in areas with heavy tree cover, dense urban environments, or when navigating through canyons or valleys. In such situations, you may become disoriented and unable to access critical navigation information.

The Importance of Contour Lines

Traditional topographic maps remain essential for navigation, particularly when traversing rugged terrain. Contour lines, which represent elevation changes, allow you to visualize the landscape and make informed decisions about route selection. By understanding contour lines, you can identify potential hazards, such as steep drop-offs or fast-moving water, and plan your route accordingly.
