How to read and use a topographic map in a survival situation - Wilderness Arena Survival
Topographic maps describe the shape of the land and can be used to help you locate natural and man-made features like woodlands, waterways, important buildings, and bridges. The information derived from a topographic map can help you locate sources for water and even if a clearly-defined water resource is not visible on the map, you can use the topographic map, which illustrates the elevation of the land, to locate low-lying areas where water may collect. Topographic maps can also help you locate the most appropriate shelter for your particular survival situation or plan potential escape routes when needed.
