Waypoints are specific locations or points of interest that are used in navigation and mapping. They help travelers, hikers, and pilots mark important spots along their route, making it easier to plan and follow a journey. Waypoints can be defined by coordinates, such as latitude and longitude, and are often used in GPS devices and mapping software. In outdoor activities, waypoints can indicate landmarks, campsites, or water sources. They are essential for ensuring safety and efficiency, allowing users to track their progress and make informed decisions about their route. Waypoints can also be shared among users, enhancing collaboration in activities like geocaching or orienteering.
