Quick Answer
To use topographic maps during a survival scenario, locate your position, identify nearby landmarks, and determine the best route to your destination. Study the map's contour lines, elevation, and water sources to navigate effectively.
Reading Contour Lines
When using a topographic map, focus on contour lines to understand the terrain’s shape and elevation. Contour lines are typically spaced at 20-50 foot intervals, with closer spacing indicating steeper slopes. To read contour lines, follow the direction of the lines to identify hills, valleys, and ridges. Look for areas with dense contour lines to locate steep terrain or obstacles.
Locating Water Sources
Topographic maps can help you identify potential water sources, such as streams, rivers, and lakes. Look for areas with low-lying terrain, as these are often prone to water accumulation. Also, check for contour lines that form a circular or oval pattern, which may indicate a lake or pond. If you’re unable to find a visible water source, use the map to locate areas with dense vegetation or a consistent moisture pattern.
Using the Map’s Legend and Symbols
The legend and symbols on a topographic map provide valuable information to aid your navigation. Familiarize yourself with the map’s legend to understand the symbols and colors used to represent different features, such as roads, buildings, and vegetation. Pay attention to symbols indicating water sources, trails, and obstacles, as these can greatly impact your route and survival. Use the map to plan a safe and efficient route to your destination, and stay aware of potential hazards along the way.
