Abstract: Systems and methods are provided for displaying a portion of a map on a mobile device of a user while the user is traveling along a route. The mobile device can use a selected route and a current location of the device to load map tiles for parts of the map that are upcoming along the route. In this manner, the user can have quick access to the portions of the map that the user likely will want to view. For example, the map tiles can be loaded for the next 50 Km, and then when the stored tiles reaches only 25 Km ahead, another 25 Km of tiles can be retrieved. The amount of tiles loaded (e.g., minimum and maximum amounts) can vary based on a variety of factors, such as network state, distance traveled along the route, and whether the mobile device is charging.

Abstract: Some embodiments provide a mapping application that, at first and second instances in time, determines corresponding first and second positions of a virtual camera in the 3D map. The virtual camera identifies a particular position in the 3D from which to render a view of the 3D map and includes several reference points. The mapping application also identifies first and second groups of locations of the reference points at the first and second positions of the virtual camera. The mapping application further determines several paths in the 3D map based on the first and second groups of the locations of the references points. The mapping application also moves the virtual camera along the several paths by maintaining the virtual camera's several reference points on the corresponding several paths in the 3D map while rendering views of the 3D map in order to provide an animated view of the 3D map.
