I am working on the concept of a project that will display a zoomable satellite view of a rectangle of 70km by 30km. A number of waypoints will be displayed that show information when the waypoint icon is touched. It sounds very much like a simple Google Maps project of defined bounds but the only problem is that it must function WITHOUT internet connection.
Previous experience with Google Maps shows that data for a particular zoom level that has been already viewed is cached and remains available offline, however this is unreliable as the cache is at the mercy of the OS and totally unpredictable.
Is there a method of hard-cacheing a limited area to guarantee availability offline ?
........If not any suggestions ?
