Topo Maps US
This text provides information about a mobile application that allows users to download and view topographic maps of the United States. The maps are useful for various recreational activities such as hiking, canoeing, camping, fishing, mountain biking, Geocaching , and exploration. Users can choose from two map sources: USGS standard topographic or USGS hybrid topographic. The maps can be downloaded for offline use, allowing users to view them even without an internet connection or when they don't want to use cellular data. The application also offers location tracking, allowing users to see their current location on the map, their elevation, and the accuracy of the GPS signal. Flags can be added to the map to mark locations, such as the user's current position or other points of interest. Flags can be imported from other sources and organized by color. Trails are also included with the map downloads and can be imported from GPX files or recorded by the user. Trails can be shared with others and organized by color. The application also provides navigation features, allowing users to navigate to a specific flag by following a direction arrow that uses their compass heading. Other features include the ability to measure distances between points on the map and view elevation profiles of recorded trails. However, it is important to note that continuous use of GPS in the background may significantly decrease battery life.
