Online maps are digital representations of geographic areas that can be accessed through the internet. They provide users with detailed information about locations, routes, and landmarks. Popular services like Google Maps and Apple Maps allow users to search for addresses, view satellite imagery, and get directions for driving, walking, or public transportation. These maps often include features such as real-time traffic updates, street views, and user-generated content like reviews and photos. Online maps are widely used for navigation, planning trips, and exploring new places, making them essential tools for both everyday travel and adventure planning.
