Waypoints are specific geographic locations used in navigation to help guide travelers along a route. They can be defined by coordinates, such as latitude and longitude, and are often marked on maps or GPS devices. Waypoints serve as reference points, making it easier for hikers, pilots, and drivers to track their progress and ensure they stay on course. In outdoor activities like hiking or sailing, waypoints can indicate important features, such as water sources, campsites, or landmarks. They are also commonly used in aviation and maritime navigation to assist pilots and sailors in reaching their destinations safely and efficiently.
